Capture Inside and Outside Temp, DC Voltage

Former Member
Former Member over 10 years ago

We are looking at trying to capture both Inside and Outside building temp, and DC Voltage of a battery bank.

 

Is this possible with the Raspberry PI 2, to do all three or do we need to do it on three different PI's?

 

If possible, is there a code sample somewhere?

 

THanks,

    It is possible to do all things on same Raspberry Pi 2. The code will depend on which sensors you choose and wheather they use SPI or I2C interfaces.

    You can connect two one wire sensors and the ADC can measure several different things if needed. Resistor divider networks may be needed depending on the battery voltage of course
