Humidity Sensor Relay Control Module
Adjust the humidity control threshold with a potentiometer, can automatically control humidifiers and fans to decrease or increase humidity. This sensor with high power relay, can control large current equipment, when below the set value, the relay will automatically pull, start the equipment, automatically stops when reached. It is a simple and practical control system.
1. Using a high-quality HR202 moisture sensor to do detection, the surface is treated with nickel plating, widened sensing area, can improve the conductivity, to prevent rust, extend the service life.
2. Time delay function: Delay 3-5 seconds, when the humidity is detected in the critical state, the relay will not flicker.
3. Using high-quality relay, can withstand the load of 1500W, to meet the requirements of most people.
Humidity Sensor Relay Control Module Specification:
Supply voltage: 12VDC
Input current: more than 100mA
Load: 10A 250V AC or 10A 30V DC (lower than the current in this range can be used)
1. The sensor is for humidity detection.
2. The blue potentiometer modules are for soil moisture threshold adjustment. Turn it clockwise, controls higher humidity; turning it counterclockwise smaller.
3. The Module has a time delay function. Every time you adjust the value may need to wait for 5-8 seconds, check the change of the relay and green LED lights, until it meets the requirements.
