I 'd like to developp a project on ruuvi to:
-measures two different voltages ( 2 batteries of 12 V)
-measures the level of a water tank via an anlogic sensor giving a voltage
The measures will be transmitted by blutooth on my android phone on a dedicated webpage
I have as idea to use three different GPIO port which have ADC capabilities with resistant bridge to lessen the voltage to 5 Volts.
What is the best ruuvi firmware to use for this project ? Espruino or native firmware ? The answer must include the facilities to develop and debug on the ruuvi with my PC on windows.
Thank for your help before I begin to developp this project.
