TTGO T-Higrow Introduction

  • This capacitive soil moisture sensor differs from most of the resistive sensors on the market, using 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.


  • Since BME280 already includes a temperature and humidity sensors, it already includes the function of DHT11, we have removed the DHT11 sensor on the BME280 version to reduce costs.
