  • Wireless Carbon Monoxide Detection with Sensorfi

    As you are likely aware, Carbon Monoxide detection is crucial being this a toxic gas that you cannot see or smell.

    According to the CDC - (Centers for Disease Control & Prevention) CO is given off whenever fuel or other carbon-based materials are burned. CO usually comes from sources in or near your home that are not properly maintained or vented.
    You may be exposed to unsafe levels of CO by:

    Using poorly maintained or unvented heating equipment;
    Improperly vented natural gas appliances like stoves or water heaters;
    Running vehicles in garages or other enclosed spaces;
    Using a gas stove, grill, or oven to heat the home;
    house or building fires;
    Clogged chimneys or blocked heating exhaust vents;
    Running generators or gas-powered tools indoors or outside near windows, doors, or vents;
    Cooking with a charcoal or gas grill inside the home or other enclosure;
    Using a propane camp stove, heater, or light inside a tent; and
    being near boat engine exhaust outlets.

    Visit the the CDC website for more information here.

    With winter approaching and more furnaces running, I thought it necessary to share how easy it is to create a wireless sensor network to detect CO at home or in the workplace.

    Wireless Carbon Monoxide Sensors Create a simple wireless sensor network to detect Carbon Monoxide

    Sensorfi makes it easy to use many of these sensors without the use of wires, perfect for a commercial building, office space or home.

    These sensors have a range of 0-1000 PPM and will notify you immediately on a mobile device or computer if CO is detected.

  • Wireless Temperature Sensors for Server Rooms

    Wireless sensors for server rooms
    Server rooms, some are maintained well, others …. Not so much.Server Room Disaster
    Most IT professionals are aware of the damaging effects that can take place in a server room with poor management, basically you run the risk of destroying servers and losing important data.

    Managing temperature in a server room is typically the number one priority when it comes to creating a good environment for servers.

    This is why most well maintained server rooms are equipped with its own cooling system separate from the rest of the facility.

    But what if this cooling system malfunctions?

    Unfortunately servers themselves create their own heat, and if not properly cooled there is a good chance that the server will be destroyed.

    Sensorfi has an easy solution to remotely monitor the temperature, and to receive notifications when something goes wrong.

    Wireless temperature sensors placed throughout the room will ensure the server room temperature is where it needs to be at all times.Temperature Sensors for Server Tooms

    This is a great start to developing a simple wireless sensor network at your facility.

    Sensorfi also has a solution for monitoring for water leaks, open or closed doors, motion and power consumption in server rooms.

    The possibilities with these wireless sensors are endless.

    Check out our page illustrating what sensors are typically used for managing server rooms.Server room temperature monitoring

  • How to Prevent my Basement from Flooding

    How to prevent my basement from flooding

    It is that time of year again when the winter snow is melting, and rain is likely in the forecast.

    Rain is great, but when it rains too much it could be a problem for a homeowner with a basement, especially if the basement is finished with carpet and sheet rock walls.

    This is why it is important to have a Sump Pump located in the basement, outside of the house, or even both.

    In the Spring of 2011, the community where I live in Northwest Iowa, experienced excessive amounts of rain.

    It seemed like everyone in the community had water in their basement!

    This was due to a few reasons, but the majority of the reasons were sump pumps in these homes were either not keeping up with the rain, not functioning, or because the power went out during a storm.

    That year sump pump sales in our community were skyrocketing to say the least!

    My house has a basement, and it is finished with carpet, has sheet rock walls, and furniture, so every spring I make sure my sump pumps are in working order.

    I have a sump pump in my basement as well as out in our front yard. I even have drain tile piping around the foundation directing the water to a deep pit with the sump pump at the bottom.

    …. So there should be no reason why I get water in my basement from rain right?


    I remember waking up after a night of downpouring rain to find a small amount of water on the carpet, and I thought, well that isn’t so bad, I mean it could have been worse.
    So I thought I was in the clear, and went to work. Then I got a phone call from my wife about an hour later telling me our basement is flooded with over an inch of water everywhere!

    I didn’t even believe her at first, because it had stopped raining and I saw the small amount of water just hours before. So I came home from work and found that the pit outside of my house was full of water, and it filled up the tile piping up with water. The soil around the foundation of my house was saturated!

    All because my Sump Pump quit working.

    I had to rip out all of my carpet, take out the furniture, and fix walls, etc.

    If I just would have known my pump quit working, I could have prevented water from getting in my basement.


    Sensorfi has the solution to this problem, wireless sump pump monitoring!

    There are a few sump pump alarms out in the market that trip an audible alarm to alert you, but I don’t think this is good enough. This does not work when you are out of the house, or your pump is outside of your house.

    Water Detection sensors with the ability to text you, and or send you an email, in my opinion is a much better alternative.
    water detection

    Track water level in Sump pits using the Water Detect Sensor
    Simply place this sensor above the water level it should never reach with a functional pump.

    Receive real time alerts if the water reaches a set level and the pump has not engaged.
    phone alert

    AC Current Meters can be used to track when the pump runs and for how long.

  • Wireless HVAC System Monitoring

    Wireless HVAC System Monitoring

    HVAC, or Heating, Ventilation, and Air Conditioning systems are functions typically combined into one system in most homes and commercial buildings for temperature comfort as well as indoor air quality.


    It is easy to disregard the maintenance involved with an HVAC system. Most people don’t know there is something wrong with the HVAC system in their building, until they notice that the temperature is far too high or low, compared to the setpoint on the thermostat.

    Even HVAC or building maintenance personnel are quite familiar with finding out there is an issue, when it is too late.

    This is why preventative maintenance is crucial.

    Sensors from Sensorfi can be a great tool to keep HVAC systems properly maintained.

    Not only do we want to keep the HVAC system to just work, but rather working properly to prevent excess energy consumption to save money.

    Below are some of the sensors we offer to remotely monitor your HVAC system performance.

    Temp sensor
    Air Flow Detection Sensors
    Water Detection Sensors

  • Wireless Data logging Solutions

    Wireless Data logging Solutions

    Using Sensorfi sensors for data logging has many advantages making the process of data logging very simple and user friendly.

    Before I explain, let’s briefly take a look at the history of data logging.

    Below is what some of the early data loggers looked like….. that’s right a person with a clipboard and pen.

    manual datalog

    Back then they would have to look at a sensor or monitor, enter the data on paper, and maybe enter it into a computer manually.

    Then there is the circular chart recorders- I still see some of these used today.

    chart record

    Also there was the continuous line or strip chart recorders.

    Strip chart

    Over the years data loggers have been designed to interface with a PC, many of these still require manually removing the data and transferring to their computer. These types of data loggers also have a limited amount of data storage available.

    Using our sensors connected to the internet, we do not have to worry about running out of memory. We also do not have to remember to manually remove the data from where it is recording.

    Using the Sensorfi online portal allows the user to generate reports from daily, weekly, to monthly intervals, making this process automatic.

    Here is an example of what a temperature data trend looks like in the online portal.

    All by simply using a temperature sensor and gateway, and logging into the online portal

  • Water Leak in School Boiler Room

    Water Leak in School

    Just recently a local school in our community experienced a water main leak in their boiler room. The school’s Superintendent said, “It must have poured out hundreds of thousands of gallons," Earleywine said at 2:30 p.m. Tuesday inside the boiler room. "It was actually shooting out like a geyser out of that drain right there two or three feet high."

    School Water Leak

    I don’t know how long it took for someone to find the mess, but I imagine this would have been found much quicker if there was a Water Detection Sensor somewhere present in the boiler room. Using this type of sensor could have sent a text message reading something similar to, “Leak in Boiler Room” and notified a custodian to shut the water off much sooner, preventing more damage.

    It is not difficult to set up a wireless sensor network to make a “Smart School.”

    I can only imagine how beneficial it would be to a school to remotely monitor heating/cooling systems, server rooms, boiler rooms, etc. to make life a little easier.
    Sensorfi, has the products necessary to prevent such a disaster.

    Place water sensors near water heaters, boilers, radiators, or other areas where water should never be present. Minimize potential damage to tile, wood floors, masonry, carpet, etc. Monitor pressurized water inlets or junctures for blowouts easily using our water detection sensors.

  • What is the Internet of Things?

    Introducing Sensorfi

    Hello, and welcome to the Sensorfi Internet of Things Blog!

    This blog is intended to discuss wireless sensor technology, and how we can use it in our everyday lives.

    I personally believe that this technology will be used in more places more frequently in the years to come. This is easy to believe when you observe how far communications technology has improved over the past decade. It seems as if most people we know own a cell phone, or even a “smart phone”. Every day we come a little bit more connected. This brings me to “Iot” or the Internet of Things.

    What is the Internet of Things?

    This is what Wikipedia has to say:

    The Internet of things (stylised Internet of Things or IoT) is the internetworking of physical devices, vehicles (also referred to as "connected devices" and "smart devices"), buildings, and other items—embedded with electronics, software, sensors, actuators, and network connectivity that enable these objects to collect and exchange data.[1][2][3] In 2013 the Global Standards Initiative on Internet of Things (IoT-GSI) defined the IoT as "the infrastructure of the information society."[3] The IoT allows objects to be sensed and/or controlled remotely across existing network infrastructure,[4] creating opportunities for more direct integration of the physical world into computer-based systems, and resulting in improved efficiency, accuracy and economic benefit in addition to reduced human intervention.[5][6][7][8][9][10] When IoT is augmented with sensors and actuators, the technology becomes an instance of the more general class of cyber-physical systems, which also encompasses technologies such as smart grids, smart homes, intelligent transportation and smart cities. Each thing is uniquely identifiable through its embedded computing system but is able to interoperate within the existing Internet infrastructure.

    So to summarize, we can use sensors on almost anything we can imagine, connect them to the internet, let the sensors make decisions for us, monitor trends over a specific period of time, and much more. All just by opening up an app on our smartphones.

    Our goal at Sensorfi is to make this as user friendly as possible. I do not believe that you have to be an electrical engineer, or a computer wizard to setup and use wireless sensor technology for your home or business.
