ESP32 WIFI Bluetooth DHT11 Temperature and Humidity Soil Module

Description:
You can now easily measure temperature, humidity, soil moisture and light intensity remotely via Wi-Fi with the ESP32 HiGrow-type Soil Sensor Board from PMD Way.
This interesting board is designed to be placed into soil, and uses a capacitive soil sensor to measure moisture - along with a light sensor and DHT11 temperature/humidity sensor.
The host microcontroller is the popular ESP32 series and has a full USB interface via a CP2104. Power is provided by an 18650 LiPo battery (not included) and you can charge thi The battery life is much longer than before. In the case of testing water, you can test the soil salt and photosynthetic absorption, reasonable fertilization and proper sun exposure.
This capacitive soil moisture sensor is different from most resistive soil moisture sensors on the market, and uses the capacitive sensing principle to detect soil moisture. The problem of the resistance sensor being easily corroded is avoided, and its service life is greatly extended.
