HW-390 Capacitive Soil Moisture Sensor Module Wide Voltage Corrosion Resistant 3.3-5.5V DC
Feature:
1. A new type of soil moisture sensor! This capacitive soil moisture sensor is different from most of the resistive sensors on the market. It uses the principle of capacitive sensing to detect soil moisture. It avoids the problem that the resistive sensor is easily corroded, and greatly extends its working life.
2. The sensor has a built-in voltage regulator chip, which supports 3.3~5.5v wide voltage working environment, which means it can work normally even on the 3.3v Arduing and main control board. Mini PCs such as Raspberry Pi only need an external ADC (analog signal to digital signal) conversion module to work.
3. With an external screen and a motherboard (NOT included), you can talk to your plants! See if your beloved is thirsty, and need more water to moisturize it.
