Monitoring and alerting on my phone

A project log for Car Battery Monitor

Monitor the voltage of a 12V car battery in order to get early warning that the battery is becoming discharged

I have been using the IoT ThingSpeak Monitor Widget to view the current state of the battery on the home screen of my Android phone. The widget obtains the latest battery voltage from my ThingSpeak channel. The widget also contains configurable monitoring functionality so that if the voltage falls below a threshold then an alarm occurs.
