How To Test Outdoor Light Sensor

Outdoor light sensors are an essential part of any home security system. They detect movement and trigger lights, which can deter burglars and other criminals. However, over time, outdoor light sensors can become less sensitive or even stop working altogether.

If you're having problems with your outdoor light sensor, there are a few things you can do to test it:

Check the power supply. Make sure that the light sensor is plugged into a working outlet and that the power switch is turned on.
Clean the sensor. Dirt, dust, and cobwebs can build up on the sensor over time, which can block its view and prevent it from detecting movement. Use a soft cloth to clean the sensor gently.
Adjust the sensitivity. Most light sensors have a sensitivity adjustment knob. If the sensor is not detecting movement, try turning the knob up to increase the sensitivity.
Test the sensor. Once you have cleaned and adjusted the sensor, test it by walking in front of it. The light should come on within a few seconds.

If you have tried all of these steps and the light sensor is still not working, it may need to be replaced.
