INTRODUCTION This is a new type of analog capacitive soil moisture sensor designed by DFRobot. Compared with the old soil moisture sensor, it has increased waterproof performance. Even if the sensor is fully immersed in water, it can still be used normally; the anti-corrosion performance is optimized and more Laminate design, no longer need to worry about the sensors in the soil scratching the sensor panel, resulting in accelerated corrosion of the sensor; the length of the electrode plate is increased and the circuit performance is optimized, the measurement range is expanded, and the measurement value of the sensor is more accurate!
SPECIFICATION Supply Voltage: 3.3 ~ 5.5VDC Interface: 2.54-3Pin Output Voltage: 0 ~ 3VDC Cable Length: 1.5m Dimension(L x W): 175 x 30mm / 6.89 x 1.18 inches
