I've came up with a customized development of a battery tracking system.
it is a kind of telemetry that will report voltages, temperatures and more data in the future.
my goals were:
- to be able to set the alarm at different voltages (sometimes 3.0v/cell, sometimes 3.3v)
- to be able to use a variety of batteries - different voltages.
- to be able to report that the signal is lost, - extremely important
- long range and high reliability -still to be improved:
the "smart" modem modules are on the way - should do ~1km
Ground tracking unit (RX)
Air tracking TX (on vehicle):
