Description This capacitive soil moisture sensor is distinguished from most resistive sensors on the market and uses capacitive sensing to detect soil moisture The problem that the resistance sensor is easily corroded is avoided and its working life is greatly extended The sensor has a built in voltage regulator chip that supports a 3 3 volt working environment which means it works even on a 3 3Vcontrol board A miniature PC such as the Raspberry Pi only needs an external ADC analog to digital signal conversion module to work With an external screen and a motherboard you can talk to your plants See if it is thirsty and you dont need more water to moisten Operating voltage 3 3 VDCOutput voltage 0 3 0 VDCInterface PH2 54 3PSize 98 x 23mm LxW Package included 3 x Capacitive Soil Moisture Sensor
