The Samsara Environmental Monitor (EM) is a wireless and waterproof temperature and humidity sensor. Samsara EM-series monitors are ideal for monitoring food safety during transportation, warehouse conditions, and other applications that rely on environmental data to ensure quality or maintain compliance.
Warning
Samsara EM sensors are not intended to be used as a primary method of detecting fires or monitoring life threatening conditions.
The Samsara temperature monitoring sensors use thermistor-based temperature sensors to reliably monitor the temperature without the need for periodic recalibration. The sensors use a Silicon Labs 7013 module which is factory calibrated and tested in a controlled environment. For more information, see the Certificate of Calibration which certifies each Samsara EM sensor has been calibrated to read temperature and humidity according to the specifications noted in the EM series datasheet. After sampling the environment, the Samsara EM sensor delivers the new data within seconds.
Before you can begin using your EMs, Install an Environmental Monitor Sensor, then pair your sensor to start monitoring conditions from your Samsara dashboard.
