Wireless Temperature Sensor

The wireless temperature sensor uses a thermistor to accurately measure temperatures from -20°C to 85°C. Perfect for slower changing temperatures and critical applications such as facilities or rooms. User customization allows you to set the frequency of readings and the ability to set thresholds for "Alarms", "Alerts" and "FYIs".

Need Longer Battery Life?
Monnit WIT2 Sensors provide the same features and benefits of our standard sensors but with the added value of AA batteries. The AA battery option is more robust at a wider temperature range and provides extremely long life for quicker heartbeats.

2 replaceable AA 1.5V batteries.
At 1 hour heartbeat setting, included AA batteries will last more than 4 Years. **
Robust sensor housing.

** Battery life is determined by sensor reporting
frequency and other variables.
