useThe way:
Through the potentiometer to adjust the humidity of soil control threshold, relay often start can be automatic in garden, garden automatic watering, family flowerpot soil humidity control, all kinds of electronic games, with high power relay, and the relay can control large current device, below the setting humidity automatic start relay, greater than setting humidity automatically disconnect.
Product introduction:
1 using the company's production of high quality soil sensor to do the detection of soil moisture, the widening of the sensing area, can improve the conductivity;
2 products can be a wide range of soil humidity control, regulation and control of the corresponding threshold through the potentiometer,The humidity is lower than the set value, start relay, is higher than the set value, the relay is switched off;
3 products using high quality relay, can withstand the load of 1500W, to meet the requirements of most people;
4 products with power indicator and indicator relay;
Electrical parameters:
Power supply voltage:12VDCInput current: more than 100mA
Load: 10A 250V AC or 10A 30V DC (lower than the current in this range can be used)
Module instruction:
1 sensors applied to the detection of soil moisture;
Module 2. Blue potentiometer is used to soil moisture threshold adjustment, the adjusted counterclockwise, the humidity control will be bigger, clockwise smaller;
Delivery list:
The soil humidity control module and 1 sets of soil sensors, 20cm long 2P red line 1
Soil sensor and relay module wiring:
The relay output terminal pin is stated as follows:
