Wireless Duct Temperature Sensors

Monnit wireless duct temperature sensors use an NTC type thermistor with 8 ft. UL listed plenum cable to accurately measure temperatures in duct work, while maintaining a sealed environment. The sensor will measure temperature in the duct work and send data to the iMonnit Online Sensor Monitoring and Notification System. The data is stored in the online system and can be reviewed and exported as a data sheet or graph. User customization allows you to set notifications and alerts from the system so you can know immediately if temperatures are above or below an optimal range. The sensor probe features mounting flanges and can be easily installed for long term use.

Wireless Duct Temperature Sensor Features:

    • Accurate to ± 1° C (± 1.8°F).
    • Increased accuracy by user calibration to ± 0.25° C (± 0.45° F).
    • Probe temp range of -40°C to +150°C (-40°F to +302°F).
    • 8 ft. UL listed plenum cable.
    • Mounting flanges for easy securement
    • FCC and IC certified

Let's take a look into our crystal ball to see what the future holds at Monnit

Monnit's development team is always hard at work developing new wireless sensing products and enhancing our existing products based on customer feedback. We are currently working on a new thermocouple sensor that will allow for interchangeable thermocouple temperature probes. Among the interchangeable probes for this sensor are a chimney / flu temperature probe as well as food grade temperature probe. If you would like to learn more about the development efforts of our thermocouple sensor or be notified when it becomes available, please email us at sales@monnit.com.

Using Temperature Sensors to Prevent Frozen Pipes and Water Sensors to Detect Plumbing Leaks.

As we have entered the winter season here in the United States, we receive many calls requesting our wireless temperature and water sensors for use in both commercial and residential properties to help minimize the potential for damage due to frozen water lines.

When water freezes it expands putting pressure on pipes, valves, tubing, and hoses. The result is often costly and very time consuming to fix. In a matter of minutes a one-eighth inch crack can release 250 gallons of water and disrupt your life in ways you never imagined. It is always smart to insulate pipes that are exposed and where possible, turn off water lines and drain pipes that are not in use. However, these precautions are not always feasible and do not always work.

So, how do you ensure that your pipes don't reach freezing temperature and know if there has been a break? We recommend using Monnit's affordable wireless temperature sensors to monitor the temperatures around your water pipes and wireless water detection sensors to know immediately if there is a broken pipe leaking. There are no wires to worry about, the setup process is simple and quick, and the you can monitor everything from any Internet enabled computer, tablet or smart phone.

Quick Stats:

Enjoy the winter months without worrying about the potential damage of broken water pipes.

Using Monnit Wireless Sensors to Remotely Monitor Boiler Systems

With the change in seasons we sometimes see fluctuations in our heating or cooling needs. Whether you are located in Florida where they are currently seeing record highs in the 90's or Oregon where the weather is in the mid 10's it is important to keep track of your heating and cooling systems to make sure they are performing as needed. Monnit provides an easy to use remote monitoring solution to track heating and cooling systems for efficiency and preventive maintenance.

To get started, we suggest purchasing a Monnit HVAC Monitoring starter bundle as it will include all the devices needed to remotely monitor one HVAC or boiler system. Bundles can be purchased here. Alternately you can purchase the devices separately if you wish to use a different gateway or coin cell version of some sensors for the indoor portion of the installation.

The devices we recommend are:
    1 - Wireless Gateway
    1 - Industrial Wireless Quad Temperature Sensor
    1 - Industrial Wireless AC Current Meter (150 Amp)
    1 - Wireless Duct Temperature Sensor
    1 - Wireless Temperature Sensor (with Probe)

Boiler System Installation

Before starting any part of this installation process, shut the power off to boiler system. Start by installing a Monnit wireless gateway. The gateway can be located anywhere in the building where it has access to power and a decent cellular signal (for Cellular gateways) or access to an internet router (Ethernet gateways) or PC (USB gateways).

We recommend using a Monnit industrial wireless quad temperature sensor which has 4 independent temperature probes that can monitor and collect temperature readings for key areas of the boiler system. Each temperature probe is labelled 1 through 4.

Start by connecting each of the temperature probes to the pipes feeding the radiators making note of which probe you are connecting to each. Depending on the number of zones you have you may want to add additional sensors if you would like to track them all. Alternately if you have fewer zones, you can also track the radiant return line or ambient temperature near the boiler. When connecting a temperature probe to any of the boiler pipes, we recommend using a zip tie to securely fasten the probe tight against the bare metal pipe. After securing the temperature probe use thermal tape to completely wrap the probe to the pipe to provide a thermal barrier allowing the sensor to get a more accurate reading of the pipe temperatures. We also recommend using a wireless duct temperature sensor or a wireless temperature sensor (with probe) to monitor the outside ambient air.

The Monnit industrial wireless AC current meter (150 Amp) can be used to track the current draw of the boiler pump. The AC current meter uses a clip-on current transformer that should be clamped around the "hot" power wire feeding the boiler pump. Excessive current draw by the pump can signify that the pump is beginning to fail and should be checked and/or serviced.
