Monnit wireless temperature sensors use a thermistor to accurately measure temperatures. These sensors are perfect for monitoring ambient temperatures around the sensors physical location. User customization allows you to set the frequency of readings and the ability to set thresholds for alerts via SMS text and/or email.
Industry leading 25 month NIST certified product included on leaded temperature sensors (select a lead length in order to see available certifications).
The Temperature Sensor is not meant for wet, damp, high humidity environments. This sensor should only be operated in dry, low humidity environments. Should you need a temperature sensor that operates at extreme temperatures and can withstand getting wet or condensed on, please consider our industrial sensors.
In order to program the sensor to connect to your wif-fi network, you will need a Wi-Fi programming cable and the free MoWi setup utility. The MoWi setup utility is currently available for Windows® PC's only. Mac and Linux are not currently supported!
