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.
Already have NIST certified sensors and now need to renew the certification?
ALTA sensors offer 3 to 4 times the range of standard sensor platforms, extending non-line-of-sight reach to an exceptional 1,200+ feet through walls (12-14 walls typical). Using Frequency-hopping Spread Spectrum (FHSS) also allows ALTA sensors to have better interference immunity from other wireless devices.
Superior power management provides ALTA sensors with almost twice the battery life of Monnit’s standard wireless sensors.
Integrated on-board data storage allows ALTA sensors to store data messages if communication to a wireless gateway is disrupted (power outage, Internet outage, or out of range). Messages that can’t be delivered will be time-stamped and stored in memory (up to the last 512 messages) until communication with the gateway is restored, at which point the messages will all be transmitted.
Over-the-air updates allow ALTA products to be updated remotely if new fixes or features become available.
If ordering NIST certified temperature sensors orders may take up to 6 weeks to ship.
* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
