Designed for use with the Shelly Plus 1 and Shelly Plus 1PM, the Shelly Temperature Sensor offers 9-bit to 12-bit celsius temperature measurements, requiring only one data line (and a ground) to function. It also includes an alarm function if temperatures fall outside acceptable levels, and is IP67 rated for both dust and waterproofing.
 
Applications for the temperature sensor range from HVAC environmental controls, to measuring temperature inside buildings, equipment, or machinery.
