The NEST Protect has several sensors.
-Smoke Chamber and Sensor
-Carbon Monoxide Sensor
-Activity Sensors (three)
The Smoke Sensor is (I believe) what actually sets off a fire alarm.
The Heat Sensor is used to detect a sudden rise in temperature. Since this does not necessarily mean a fire, it does not set off the alarm (I believe) but when the sudden temperature increase is detected, it will make the Smoke Sensor more sensitive.
The Carbon Monoxide Sensor will both warn you, as well as notify your NEST Thermostat (if you have one linked to your account) so that the Thermostat can shut down the furnace, in case that is where it's coming from.
The Activity Sensors (there are 3) are used for 3 things. 1) Path light (turns on a light at night in the dark when you are walking under it to help you see) 2) Tell your NEST Thermostat (if you have one) when your home to help improve its Auto Away feature, and 3) for the NEST Protect Wave feature, to silence the 'nuisance alarms'. At the time I am writing this, the NEST Wave feature is currently disabled while they work to improve it.
The Light Sensor is used to tell when the lights are out at night, so it knows when to turn on its Path Light feature when you walk by, and also to flash its status when you turn off the lights at night. (will flash green for 'all is well' or yellow if lot battery (if you have the battery unit) of if a sensor isn't working)
