* 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 resistive sensor is easily corroded is avoided, which greatly prolongs its working life. * The sensor has a built-in voltage regulator chip that supports a 3.3~5.5V wide voltage working environment, which means it works even on the 3.3V A-rduino main control board. A miniature PC such as the Raspberry Pi only needs an external ADC (analog signal to digital signal) conversion module to work. * With an external screen and a motherboard, you can talk to your plant! Look at the beloved, is it thirsty, need not need a little more water to moisturize.
