ESP32 HiGrow-type Soil Sensor Board with WiFi Bluetooth DHT11 and Battery Support
You can now easily measure temperature, humidity, soil moisture and light intensity remotely via WiFi 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 this via the micro USB socket.
Example code for Blynk.cc and Thingshare (both via Arduino IDE) can be found here.
