AJMRTC light-sensitive relay module uses a photoresistor to sense surrounding light intensity. When ambient brightness drops below your preset value, the relay will activate automatically to turn on loads such as car lights. You can turn the onboard potentiometer to calibrate the sensitivity threshold easily. It works with 12V DC power, making it suitable for car automatic lamp modification, garden lighting, and light trigger DIY projects. The reverse polarity protection prevents module damage from wrong wiring. This listing contains 2 pieces of photoresistor relay modules. Loads and power supply are not included.
