Sensor operating temperature

Samsara Environmental Monitors are powered by lithium batteries that can operate within a wide range of temperatures without sacrificing battery life. Samsara Sensors can be placed in most residential, commercial and industrial environments without adversely affecting their performance.

Samsara sensors can be placed in refrigerators and freezers for accurate temperature and humidity readings in those environments.

For temperatures below normal freezer temperatures (approximately -20 Degrees C or -5F), the EM21 will operate, however, for prolonged battery life we recommend installing an EM22 sensor outside the appliance and using the included probe to monitor the temperature inside the freezer.
