Features: Module Operating Voltage: 5V Output Type: Output Switch Control Capacity: Maximum 10A Detection Frequency: 1MHZ Load Capacity: 10A/AC 250V or DC up to 30V RED LED ON: Indicate the Power ON BLUE LED ON: Relay is working Module output terminal has three ports Working Temperature: -20 ° C ~ +85 ° C Indicator Light: LED Installation: Screw fixation Weight: about 0.1KG Size: 53*31*19MM XH-M131 DC 5V Light Control Switch Photoresistor Relay Module: Light threshold can be adjusted by potentiometer to set the relay start. Using the photoresistor induction light intensity comes with the relay, direct control load. Distribution bit sensitivity adjustment, start relay threshold set by adjusting potentiometer, when the dark this threshold, the module relay is energized, bright this threshold, the relay release. 5V power input is designed for relay board regulator transistor to provide sensor Used to make the product more stable and reliable. onboard optocoupler isolation drive relay, the effective protection of the chip to make the product more reliable work. Has four fixed bolt hole for easy installation. 5V power input is designed for relay board regulator transistor to provide sensor Used to make the product more stable and reliable. onboard optocoupler isolation drive relay, the effective protection of the chip to make the product more reliable work.
