Description
Temperature display
Uses an Wemos D1 mini with a GXHT30 I²C sensor and a SSD1306 I²C 0.96" OLED display to measure and display the ambient temperature & humidity..
This project supports OTA updates, uses the WiFi manager to configure the WiFi and provides a REST API to get the temperature and humidity as JSON. The readings (and display) are updated every 2 seconds and also output to serial. For more information and the code check out https://riii.me/td1.
