Happy Store Arduino Moisture Sensor Soil moisture sensor automatic watering special
Detailed Product Description Arduino Moisture Sensor Soil moisture sensor automatic watering special This is a simple water sensor can be used to detect soil moisture, soil water deficit, the sensor output value will be reduced, which in turn will increase. Use this sensor to produce an automatic watering device, so that the plants in your garden do not have people to manage. The sensor surface of the gold-plated handle, you can extend its service life. Into the soil, and then use the AD converter to read it. His help, the plant will remind you: Hey, I'm thirsty, please give me some water. Technical Specifications Supply voltage: 3.3V-5V Operating Current: 15mA maximum The output voltage of 0 - 2.3 V [2.3V is completely immersed in water, voltage, 5V power supply, the humidity the greater the output voltage the greater. Interface definition: a foot signal, 2 feet to 3 feet power is Service life: approximately 1 year (gold plated handle, strengthened the electrical conductivity and corrosion resistance) Module size: 60X20X5mm
