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.
Note:
- 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.

Electronic Components, IoT & Wireless Boards, Microcontroller BoardsESP-01 ESP8266 Wifi Serial Module For IOT
The ESP8266 WiFi Module is a self-contained SOC with an integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. The ESP8266 is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. This module comes with AT commands firmware which allows you to get functionality like Arduino wifi shield, however, you can load different firmware to make your own application on the modules’ memory and processor. It’s a very economic module and has huge and growing community support.
