Yes a PIR sensor does work at night. In general, they work better at night than during the daytime.
PIR = passive infared They detect motion and then activate a switch to turn things on and off
The PIR sensors use the detectors or pyroelectric sensors to work. Example include the automatic door openers.
A PIR Sensor can be purchased at any specialty electronics store. It is a sensor primarily used for sensing changes in infrared energy. It is a highly specialized motion detector.

A PIR Motion sensor detects the minute changes in heat and infrared radiation rather than movement.
A Passive InfraRed Sensor (PIR)
Normally a PIR sensor has three cables. Brown: + Blue: - Red: Sensor control Connect the brown and the blue to your power in. All lamps must be connected to blue and red. When the sensor detects movement it "transfers" the ingoing power from the brown wire to the red wire meaning that the lamps for a given period has both + and - = the light up.
Yes but the dawn to dusk feature normally built in may not operate correctly due to low light levels but the PIR function will work perfectly well.
