LEAP#343 ESP8266 DHT11 Sensor Reading

The DHT11 sensor is a very cheap and common sensor that provides readings of relative humidity (20-80% ±5%) and temperature (0-50°C ±2°C).

I’ve used this before with an Arduino, this time I’m testing with the most basic ESP8266 board - an ESP-01, which exposes one free GPIO. For coding I’m using ESP8266 core with the Arduino IDE, and the Adafruit sensor library to interface with the DHT11.

As always, all notes, schematics and code are in the Little Electronics & Arduino Projects repo on GitHub hero_image
