Description: 
This sensor uses the capacitive sensing principle to detect soil moisture. It avoids the problem that the resistance sensor is easy to corrode and greatly prolongs its working life. This sensor measures soil moisture levels by capacitive sensing rather than resistive sensing like other sensors on the market. It is made of corrosion-resistant material that provides an excellent service life. This module includes an on-board voltage regulator which gives it an operating voltage range of 3.3 ~ 5.5V. It is perfect for low-voltage MCUs, both 3.3V, and 5V. For compatibility with a Raspberry Pi, of course, it needs an ADC converter.
This module uses ESP32 Bluetooth board and it can support Arduino and Nodumcu boards.
Some features added to this module such as sleep button wake function (IO35), function of testing soil salinity (CD4060BM + TL034IDR), light (BH1750FVI) intensity test and finally External device expansion is reserved.
The battery life is much longer than before. In the case of testing moisture, you can test the salt and photosynthetic absorption of the soil, reasonable fertilization and proper sun exposure.
