The Nest Temperature Sensor works in tandem with the Nest Learning Thermostat to gauge the temperature in other rooms in the house. Most homes aren’t the same temperature in each room, but the Nest Temperature Sensor tells your Nest learning Thermostat which room should be a certain temperature at a certain time of day. It can be placed on a wall or shelf to get the right temperature where you want it. Note that a Nest Learning Thermostat is required in order to use the Nest Temperature Sensor.
