Photocell Day Night Sensor - Geld Tech Presents our Photocell Day Night Sensor. Photocell sensors are electrical devices that detect the amount of ambient light present in the environment by dynamically changing switch state. This detector allows us to create smart devices that automatically switch On at night and Switches Off in the morning. It can work with only one series of lights (12 to 15 led lights)
