The 1st gen Google Nest Protect has multiple sensors that allow it to know what’s happening in a room and detect dangerous levels of smoke and carbon monoxide. Its sensors can also help tell if someone is home so your other products can switch or maintain their behavior as you expect.
Nest Protect uses information from its sensors to detect potential threats in your home:
- A photoelectric smoke sensor uses light to detect smoke particles in the air.
- A carbon monoxide sensor detects carbon monoxide, an odorless and colorless gas.
