Battery Powered ESP8266 Temperature/Humidity Monitor with DHT11

About This Project This Project will check Temperature, Humidity, and Heat Index using an ESP-12f and a DHT11 sensor and will run on 2 AAA batteries (or whatever your 3/3.3v battery preference may be). During transmission the ESP draws around 72mA on average and during sleep it draws 0.05mA. I’m not sure how to calculate how long that will last, but updating only every 10 minutes it should last for quite some time! The Arduino sketch is below and requires the DHT sensor library by Adafruit v…
