nodeMCU board and Adafruit Si7021 temp/humid sensor help
Posted: Mon Feb 27, 2017 11:10 am
Hi all, I have an Adafruit Si7021 temperature and humidity sensor that works great on my Uno but I've moved on to an esp8266 for the small form and WiFi but am having a lot of trouble finding a way to get them to work together. The Si7021 uses the I2C ports on the Uno which I know the esp8266 doesn't have but I know there is a work around, and I'm sure it involves the wire.h library but I'm finding bits and pieces of documentation and it would be great if someone could lay it out for me
