SwitchDoc Labs Modifications for ESP8266 This is a library for the AM2315 Humidity & Temp Sensor www.switchdoc.com This works for both the SwitchDoc Labs AM2315 and the Adafruit AM2315 Note: There are ESP8266-12 modules that have pins 4 and 5 reversed. The one we are testing has these lines reversed, hence the statement: Wire.begin(5,4); If you have the lines in your ESP8266 correct, then change this to Wire.begin(4,5) This is a library for the AM2315 Humidity + Temp sensor Designed specifically to work with the AM2315 in the Adafruit shop ----> https://www.adafruit.com/products/1293 These displays use I2C to communicate, 2 pins are required to interface Adafruit invests time and resources providing this open source code, please support Adafruit and open-source hardware by purchasing products from Adafruit!
