BMx280 and Adruino ProMini based enviromental node with LMIC ABP
Description : A low power BMx280 based datalogger for the ThingsNetwork with deepsleep support and variable interval
Revision : 2017 jul-17 1.0 first "beta"
Hardware used :
- Arduino Pro-Mini 3.3V Modified with aditional resistors to allow vcc measurment by internal 1.1V reference (so max measurment is 4.4V) Mod > GND ---[33K]--- A3 ---[100K]--- VCC
- RFM95W
- BMx280 sensor.
Software used :
- LMIC https://github.com/matthijskooijman/arduino-lmic
