Description
Description: 1g the company’s high-quality soil sensors do detect soil moisture , the surface of nickel plated , has widened the induction area can improve conductivity, prevent contact with the soil rust problems and prolong life ; 2 two products can control a wide range of soil moisture , the corresponding threshold by adjusting potentiometer control , humidity is below the set value, start relay , while higher than the set value, the relay is disconnected ; 3ucts with the delay function , delay of 3-5 seconds , when the humidity is detected in the critical state, the relay will not blink , flicker occurs ; 4-quality products using Songle relay can withstand 1500W load , to meet the requirements of most people ; 5ucts with power indicator and relay instructions ; Parameters: Supply voltage: 12VDC Input Current: more than 100ma Load: 250V 10A AC or 30V 10A DC ( below current in this range can be used) Package included: 2* LM393 12V Soil Moisture Relay Module 2* 20cm DuPont wire
