• This capacitive soil moisture sensor is different from most of the resistive sensors on the market. It uses the principle of capacitive induction to detect soil moisture.
• It avoids the problem that resistance sensor is easy to be corroded and prolongs its working life greatly.
• The sensor has a built-in voltage regulator chip, which supports a 3.3-5.5V wide voltage working environment, which means that it can work normally even on the 3.3V main control board for Arduino.
• Microcomputers such as for raspberry pi can work only with an ADC (analog signal to digital signal) conversion module.
• With an external screen and a motherboard, you can talk to your plants.
