Description:
Through the potentiometer adjusting soil moisture threshold control, automatic in garden, garden automatic watering, family flowerpot soil humidity control, all kinds of electronic games, with high power relay, can control large current device, less than setting humidity automatic start relay, greater than setting humidity automatically disconnect and delay function, without delay of critical humidity state relay don’t stop flicker problem solving is a simple and practical soil humidity control system.
Humidity is lower than the set humidity start referring to is when soil moisture is lower than setting humidity, the relay will automatically pull in, start the spray, water pumps, etc. do humidifying movement, reaches the desired humidity automatically stop.
Specifications
- Supply voltage: 5VDC input current: more than 100mA.
- Load: 10A 250V AC or 10A 30V DC (lower than the current in this range can be used)
Instructions:
- Sensors applied to the detection of soil moisture;
- Blue potentiometer is used to soil moisture threshold adjustment, clockwise adjustment and control the humidity will be bigger, counterclockwise smaller;
- Due to the module with delay function, adjust the humidity value, once every tune need to wait about 5-8 seconds, see the change of the relay, the green LED lamp also has the corresponding change, until adjusted to meet the requirements.
Package List:
- 1 x Soil moisture control module and soil sensor
- 2 x 20cm long DuPont line
