XH-M131 5V Photoresistor Relay Module
XH-M131 5V Photoresistor Relay Module offers multiple functions, such as light detection and brightness detection. It also includes a power indicator light (red) and relay indicator (blue), along with four M3 screw mounting holes for easy installation. Users can adjust the sensitivity of the potentiometer on the board. Additionally, the relay allows for various brightness detection and control options, making it suitable for tasks such as automatically turning on street lights at night and turning them off during the day. This makes it a valuable component in any automation equipment.
Characteristics of XH-M131 5V Photoresistor Relay Module:
- The module is equipped with an anti-reverse function to prevent any harm in the event of a power supply reversal.
- The Potentiometer enables the adjustment of the light threshold, thereby setting the relay start.
- The module output terminal has a total of three ports.
- The red LED light signifies that the power is ON.
- The blue LED being illuminated indicates that the relay is functioning properly.
- Pin the Relay.
- Typically in the open position.
- The COM, or common terminal.
- Normally, the state of a switch described as “normally closed” ( NC ) indicates that current is able to flow through the circuit.
