DC 12V soil moisture sensor relay control module Automatic watering of the humidity starting switch

Soil Moisture Sensor 12V Relay Control Module DC 12V Soil Moisture Sensor Relay Automatic Watering Humidity Starter Switch Humidity below the set humidity Start is when the soil humidity is below the set humidity, the relay will automatically pull, start sprayer, water pump and other humidification campaign to achieve the required humidity automatically stop. Product Usage: Through the potentiometer to adjust the soil moisture threshold control, automatic watering in the garden, the garden automatic watering, family flowerpot soil humidity control, all kinds of video games, with high power relay, can control high current device, less than the set humidity automatic Start the relay, greater than the set humidity automatically disconnect the delay function, no delay critical humidity status relay blinking stop problem is a simple and practical soil moisture control system. product description: 1, using the companys high-quality soil sensor to detect soil moisture, and in the nickel-plated surface, expand the sensing area can improve the conductivity, prevent soil exposure to rust and prolong the service life; 2. This product can adjust the potentiometer, the humidity is lower than the set value, start the relay, higher than the set value, the relay is off, control the soil humidity range, and control the corresponding threshold. 3, the product has a delay function, in the critical state of the detection of humidity delay 3-5 seconds, the relay does not flicker, stroboscopic phenomenon; 4 products using high-quality relay, can withstand 1500W load to meet the requirements of most people; 5 products with power indicator and indicator relay; Electrical parameters: Power supply voltage: 12VDC Input current: more than 100mA Load: 10A 250V AC or 10A 30V DC (below the current in this range can be used) Module instructions: 1 sensor used to detect soil moisture; Module 2. Blue potentiometer is used to adjust the threshold of soil moisture, clockwise adjustment and control of humidity will become larger, counterclockwise smaller; 3, the module has a delay function, adjust the humidity value, each tuning need to wait about 5-8 seconds, see the relay changes, the green LED lights will have the corresponding changes until the adjustment to meet the requirements so far.
