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
Monnit's new Wireless AC Current Meters measure the RMS current of an alternating current (AC) system by using a current transformer that wraps around the "hot" wire of a two wire (hot, common, ground (optional)) power system. The sensor reports Minimum RMS current, maximum RMS current, average RMS current, and amp hours to the iMonnit system. The iMonnit system is capable of generating watt hour or kilowatt hour readings as well.

Let's take a look in 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 development of our new USB Pro Gateway. The USB Pro will have on-board memory, allowing it to continue storing sensor data if online connectivity or software is disrupted, and will automatically send the data when the connection is restored. The USB Pro gateway also has a simplified setup procedure as it uses standard drivers readily available across Windows platforms. Because of the on-board memory, the software does not need to constantly poll the gateway which makes it easier to develop applications for the device, especially embedded applications. If you would like to learn more about the development efforts of our team on these new products or be notified when they become available, please email us at firstname.lastname@example.org.
Using Wireless Sensors to Monitor Grocery and Food Cold Chain
Maintaining an optimal temperature in your grocery coolers and freezers is important. If the temperature falls above or below the optimal range, costly spoilage can occur. From meat or produce display coolers to ice-cream freezers, Monnit wireless sensors continuously and automatically monitor and track temperatures and will alert you in real-time if temperatures go outside a safe zone or if a cooler door is left open.
Monnit provides a low-cost, reliable, wireless monitoring solution that allows you to track conditions and receive alerts for the following types of applications:
All Monnit wireless sensors come with free basic online monitoring, allowing you to view sensor information anytime from anywhere. Receive instant notifications via email or SMS text if a set sensor condition is met or exceeded.

Using Monnit Wireless Sensors to Remotely Monitor Boiler or HVAC 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.
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).
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.
