12V soil humidity sensor relay control module is automatically watering below the humidity start switch

12V soil humidity sensor relay control module is automatically watering below the humidity start switch.

Soil moisture sensor 12V relay control module is lower than the humidity automatic watering start switch

humidity Lower than Refers to a set humidity starts when the humidity is lower than the set soil moisture, the relay will automatically pull start spray, pump, etc. do humidification operation, the humidity reaches the set automatically stopped.
use:
By adjusting the potentiometer control soil moisture threshold value can automatically garden, automatic watering gardens, flower pots home soil moisture control, electronic games, etc., with power relays, high current devices can be controlled,is less than the set humidity automatic start relay, is greater than the set humidity is automatically disconnected, and there is a delay function to solve the critical state without delay relay humidity kept flashing problem is a simple and practical soil humidity control system.
product description:
1. The soil of high quality produced by the present sensors do detect the soil moisture, the surface of nickel plated area with a widened sensing, conductivity can be improved, to prevent contact with the soil rust problem and prolong life;
2. Product can control a wide range of soil moisture, the corresponding threshold value adjustment control through potentiometer,When the humidity is lower than the set value, the start relay, higher than the set value, the relay is switched off;
3.Products with a delay function, delayed 3-5 seconds, when detecting the humidity in the critical state, the relay does not flicker, flicker occurs;
4. high-quality products using loose music relays, can withstand the load of 1500W, to meet the requirements of most people;
The product has a power indicator and a relay indication;
Electrical parameters:
Supply voltage:12VDCInput current: 100ma greater than
Load: 250V 10A AC or DC 30V 10A (current below this range can be used)
Module for use:
1. The sensor is adapted to detect the humidity of the soil;
2. Module is the blue threshold potentiometer for regulating soil moisture, clockwise regulation, controlling humidity can, the smaller the counterclockwise;
3. Because this module with delay function,When adjusting the humidity values, each time adjusting to wait about 5-8 secondsSee the change of the relay, the green LED is also a corresponding change, until transferred to a desired extent.
