DC 12V Soil Moisture Sensor Relay Control Module Automatic Watering Detect Corrosion Resistance Probe Sensor for Gardening

– Using the company’s production of high-quality soil sensor for detection of soil moisture, and the surface of the nickel plating, widening of the sensing area can improve conductive properties, prevent soil contact is easy to rust, prolong service life.

– The product can be a wide range of control soil humidity and control the corresponding threshold value by adjusting the potentiometer and the humidity is lower than set value, start relay, is higher than the set value, the relay is switched off.

– Product with the function of time delay, delay 3-5 seconds when detected humidity in the critical state, relay will not blink, stroboscopic phenomenon.

– products using high quality relay, can withstand the load of 1500W, to meet the requirements of most people.

– products with power indicator and indicator relay.
