Unicorn is an ESP8266 based high precision wireless thermometer and humidity meter. To achieve high accuracy, the sensor used is the SHT21. Once measured, the device uploads the data to variables hosted on VariPass. The whole device is designed to run off a single 18650 Li-Ion battery, and can potentially keep running for a month thanks to ESP's deep sleep functionality (Not yet tested however!). Please check the Configuration.h file for details on configuration and battery calibration.
