12V soil moisture sensor controller module low humidity start automatic watering
Humidity lower than the set humidity means that when the soil moisture is lower than the set humidity, the relay will automatically pull and start to spray water. The pump will do the humidification until the set humidity is automatically stopped.
Potentiometer can be used to adjust and control soil moisture threshold, automatic vegetable garden, garden automatic watering, household basin soil moisture control, electronic games, etc., with power relay, can control large current device, less than set humidity automatic start relay, exceed setting The humidity is automatically disconnected and has a delay function that resolves the humidity critical state without delay. The relay flicker problem is a simple and practical soil moisture control system.
1. Using the company's high-quality soil, the soil moisture sensor detects nickel-plated surface, has widened sensing area, can improve conductivity, prevent rust and easily contact with soil, and prolong service life.
2 The product can control a variety of soil moisture, and the corresponding threshold can be controlled by the potentiometer. The humidity is lower than the set value, the relay starts, higher than the set value, and the relay is turned off.
3 The product has a delay function with a delay of 3-5 seconds. When the humidity is detected to be critical, the relay does not flash and flickers.
Four high-quality products with Songler relays can withstand loads of 1500W, meeting most people's requirements.
Five products come with power indicator and relay instructions.
Supply voltage: 12VDC input current: greater than 100ma
Load: 250V 10A AC or DC 30V 10A (current below this range can be used)
Module for use:
1 soil moisture sensor for detection ;
2 module blue potentiometer is used to adjust the soil moisture threshold , clockwise adjustment, control humidity greater counterclockwise smaller ;
3 with a delay due to the module functions in the regulation of humidity values , each tune a need to wait for 5-8 seconds or so to see changes in the relay , the green LED lights also have the corresponding changes until transferred to meet the requirement.
