Useful accessories:  
BMP280 5V
 
 
 
 
 
 
BMP280 5V: Measure Temperature, Pressure and Altitude
Note: ATmega328 SDA/SCL=A4/A5 - AtMega2560 SDA/SCL=SDA/SCL
 
Download the HEX codes below, unpack, and upload to the proper Arduino board (Use a free net tool for example XLoader)
1. ATmega328-16MHz (MINI,NANO,UNO...): Hex-m328
2. AtMega2560 (Mega(ATMEGA2560)........): Hex-m2560
Based on the offered TEXT commands, you can develop your own PC, PLC ... communication code, and applications...

Text commands (use Termite for test ):
V01 - returns Temperature (C)
V02 - returns Pressure (mBar)
V03 - returns Altitude (m)
Try and Test with BScada: BScadaID_8val_v1
