Battery monitoring for the Land Rover

Battery monitoring for the Land Rover

I've been fiddling around with this project for ages, and finally got bored with staring at the blank space in the dashboard of the 110.

So, with a new Arduino board and sensor shield from Hobby Components, and an hour or so of chopping code about, the project is back on track.

Once it's all done, I'll post the full details and arduino code but the functionality is pretty simple:

 

    • Read two battery voltages (one from each battery in the vehicle), apply a bit of smoothing and display them
    • Read a third input, into which a current sensor is connected, to display the alternator charge current
    • Display the temperature from a remote sensor



 

Next on the list will be the external components:  voltage regulator, temperature sensor and current sensor.    This time round, it *will* be finished!
