ITEM NAME:Analog Capacitive Soil Moisture Sensor3.3~5.5V+ Sensor Cable Preservative OUR Descriptio n CableMaterial: plastic Color: picture color Size: 98 x 23mm wire length: 20cm Weight: 0.05 kg Feature: New soil moisture sensor! This capacitive soil moisture sensor is different from most resistive sensors in the market. It adopts the principle of capacitive induction to detect soil moisture.The corrosion problem of resistance sensor is avoided and its working life is greatly extended. The sensor is equipped with voltage regulator chip, which supports a wide voltage working environment of 3.3~ 5.5v, which means that it can work normally even on the Arduino main control board of 3.3V.A tiny PC, such as a raspberry pie, needs only an external ADC (analog to digital) conversion module to work. Plug in a screen, a motherboard, and you can talk to your plants!See beloved it is thirsty, need not need a little more water moist. Working voltage :3.3 ~ 5.5 VDC Output voltage :0 ~ 3.0 VDC Interface: PH2.54-3 p Product list :1pcs* sensor, wire We offer you what you need!
