Nest's temperature sensor is an accessory to the company'sor , intended for homes with lots of rooms, or rooms with varying temperatures. Like the name suggests, the sensor reads a room's temperature and relays that info back to your Nest thermostat, so it can make adjustments accordingly. If you've got a Nest and ever wondered why 72 degrees doesn't feel like 72 degrees in certain rooms, your home might benefit.
The device is currently for sale on the Nest website -- though it looks like there's a 13-day wait at the time we're writing this -- and in stores like Target and Home Depot. One sensor costs $39 (roughly £29/AU$52 converted), but you can buy a three-pack for $99 (£73/AU$132 converted).
