Description

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. 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. Industry leading 25 month NIST certified product available on leaded temperature sensors. (In the Customize section above, select your probe length above then select NIST Certified.) NIST certified sensors orders may take up to 6 weeks to prepare, certify and ship. * Actual range may vary depending on environment. ** Battery life is determined by sensor reporting frequency and other variables.
