This circuit uses a transformer-less design to supply power to the light sensing and relay module. This is useful when a low voltage supply is not available. The circuit will turn ON at nightfall and OFF again at dawn. The unit is easily installed by a qualified electrician, and draws a minute amount of mains electricity.
Power supply: 220 – 240 V AC
Light Sensitivity: Adjustable via Trimmer Potentiometer
PCB Dimensions: 63.5 mm X 43.7 mm X 20 mm (2.5 X 1.72 X 0.8 in.)
