Product Description


TTGO T-Higrow ESP32 Soil Tester DHT11 BEM280 Garden Flowers Temperature Moisture Sensor WiFi Bluetooth Wireless Control Meter  Description:
Buck module
T-Higrow Introduction
* This capacitive soil moisture sensor differs from most of the resistive sensors on the market, using 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.


Note:
* Since BME280 already includes temperature and humidity sensor, it already includes the function of DHT11, we have removed the
DHT11 sensor on the BME280 version to reduce costs .
