  • Remote Battery Voltage Monitoring

    Yes Stu, there are solar chargers out there already that do what I am trying to do but I am being cheap about it as the sole purpose of my solar system at this point is to power my kiwisdr.

    I opted to go with my Raspberry Pi B model and an MCP3008 ADC. There is a ton of information online showing the many different types of sensors. I've got it running now and when I run the python script I get output like this:

    ***********

     Battery Voltage: 0.00V

     Solar Input Voltage: 0.00V

     Sensor 3 Voltage: 0.00V

     Sensor 4 Voltage: 0.00V

     Sensor 5 Voltage: 9.47V

     Temperature Reading: 1023.00

     Sensor 7 Voltage: 3.09V

     Sensor 8 Voltage: 2.82V

    ***********

    Sensor 5 and 6 are the only 2 sensors in use right now. 5 is hooked to a 9V battery and I haven't figured out the code for the temperature sensor yet. I'm no programmer. Channels 6 & 7 are open pins not connected to sensors and I suspect that is why I am seeing bogus info on those pins.

    Eventually I might even figure out how to send the data over to a self hosted webpage but for now I'm gonna get a few current sensors, figure out the temp sensor, and maybe even try to learn Python...😂
