//  FARM DATA RELAY SYSTEM
//
//  BME280 SENSOR MODULE
//
//  Developed by Timm Bogner (bogner1@gmail.com) for Sola Gratia Farm in Urbana, Illinois, USA.
//  Each sensor is assigned a two-byte identifier along with a one-byte sensor type
//  !!Untested on actual hardware!!

#define SLEEPYTIME  10   //Time to sleep in seconds
#define TEMP_ID     0    //Unique ID (0 - 1023) for each data reading
#define HUM_ID      1
#define PRESS_ID    2
