About This

• 【Specifications】Operating voltage: DC3.3-5.5V, output voltage: DC0-3.0V, size: 98*23mm，Interface：PH2.0-3P, The sensor has a 3-pin "gravity" interface, which can be directly connected to the gravity I/O expansion baffle.
• 【Capacitive sensing】Soil moisture content is measured by capacitive sensing. Instead of measuring soil moisture by resistive sensing like other types of humidity sensors,It avoids the problem of resistive sensors and their easy corrosion, greatly extending its working life.
• 【DIY watering system】 If you combine this soil moisture sensor with a small water pump, hose, relay module, etc., you can create an automatic watering device. DIY kit for a device that waters when the soil is dry, freeing you from daily watering and making things easier. Rest assured when you are away for work or travel.
• 【Easy to use】Insert the soil and detect the output of real-time soil moisture data. This soil moisture meter has a built-in constant voltage chip and supports a 3.3V voltage operating environment, so it will work normally with a 3.3V master board. Micro PCs can be operated by simply connecting one external ADC (analog signal to digital signal) conversion module.
• 【Application in Various Occasions】Connect the screen and the motherboard to obtain real-time soil moisture data. Suitable for automatic watering system robots, etc. Commonly used in garden plants, humidity detection, and smart agriculture.
