Description
1-channel relay module with photoresistor for Arduino, ESP8266, ESP32, and Raspberry Pi
Relay module with photoresistor is a device that automatically controls connected circuits depending on the light level. Equipped with a light intensity sensor, it can activate devices such as garden lighting when ambient light intensity changes. Thanks to the integrated potentiometer, you can precisely adjust the module’s sensitivity and define the lighting conditions that trigger the relay.
The module is powered by 12V DC. It has four M3 mounting holes for easy installation. The PCB carries two LEDs: one indicates module power, the other shows relay activation.
Key technical features
- Sensor type: dusk light - photoresistor
- Module supply: 12V DC
- Sensitivity adjustment: potentiometer
- Relay load: up to 250V AC and 10A or 25V DC and 10A
- Sensor cable length: about 30 cm
- Dimensions: 53 mm x 31 mm x 19 mm
Example applications
- Automatic control of garden and street lighting
- Smart home systems that react to dusk
- Switching alarm systems on after dark
- Controlling blinds depending on sunlight
- Educational projects and prototypes with microcontrollers
Benefits
- Process automation without writing complex code
- Broad compatibility with popular microcontroller platforms
- Easy and fast threshold adjustment with the potentiometer
- Convenient mounting thanks to dedicated M3 holes
- Clear operating status indication with built-in LEDs
