The Automatic Dawn to Dusk Sensor Board with Relay and LDR for Solar Based Street Light is a 12V automatic light-sensing relay board with screw terminal block connections, designed for permanent outdoor installations such as solar street lights and area lighting systems. The automatic dawn to dusk sensor board uses an onboard LDR to detect ambient light level and drives a relay capable of switching resistive loads up to 240VAC, with standby current consumption under 1.5mA to 2mA depending on the configured trigger mode, making it suitable for solar battery-powered installations where standby drain matters.
The automatic dusk to dawn light control on this board can be configured for either light-activated or dark-activated relay operation — the specifications list separate current consumption figures for “Light Activated” (under 1.5mA standby, under 46mA when relay is active) and “Dark Activated” (under 2mA standby, under 45mA when relay is active) modes, allowing the same automatic dawn to dusk sensor board to either turn a load ON at night and OFF during the day, or the reverse, depending on wiring configuration. This flexibility is particularly useful in solar street light sensor board applications, where the load (LED light) should turn on at dusk and off at dawn, while a separate charge controller circuit manages daytime solar panel charging.
The screw terminal block connections on this dawn to dusk sensor relay board require proper torque and strain relief for outdoor vibration and weather exposure — loose screw terminals in outdoor installations are a common cause of intermittent relay operation over time. Available from StemVolt, this automatic dawn-to-dusk sensor board with relay and LDR is ideal for Projects builder and makers developing solar street lighting, energy-saving automation, and intelligent lighting control projects.
