5Pcs Diy 12V Automatic Watering Module Kit Soil Moisture Sensor With Time Delay

Parameter : Working voltage : 12V Input current : greater than 100ma Motherboard size : 3CM 7CM Sensor board size : 5.3CM 1.9CM Load : 250V 10A AC or 30V 10A DC (currents below this range can be used) Module function : detecting the humidity of the soil, the relay will act or reset according to the humidity of the soil Advantages introduction : 1. With delay function, delay 3 to 5 seconds, when the humidity is detected in the critical state, the relay will not frequency action and reset 2. When the soil is wet, the relay action can be selected when the relay is moving or the soil is dry (the working mode is optional). When the switch is pressed, the relay acts when the soil is wet When the switch is up, the relay acts when the soil is dry 3. The sensitivity can be adjusted. The blue potentiometer in the module is used to adjust the sensitivity of the sensor. Clockwise adjustment and sensitivity decrease. 4. The surface of the soil sensor is tinned, which can improve the conductivity, p Lees meer over de 5Pcs Diy 12V Automatic Watering Module Kit Soil Moisture Sensor With Time Delay van huismerk in de productgroep elektronica
