Hackster.io member Gorkem Ziya Yanik has created a Raspberry Pi battery monitor project which she has kindly published to the Hackster.io website for your viewing pleasure. If you are using your Raspberry Pi in locations without mains electricity, by monitoring battery voltage you can save critical data before the worst should happen.
Gorkem explains more about the Raspberry Pi battery monitor he has created using an industrial MiniIOEx. “Raspberry Pi can also be used in places without electricity. For example, water pumping stations or in areas such as animal monitoring and so Raspberry Pi work with battery. If the the values/data/image etc. are critical; it must be monitored continuously, it is important to keep the system alive. The way to do this is to monitor the battery voltage.“
“If you can monitor the battery voltage, when the battery will run out, you can replace the battery with a spare battery. With the industrial Raspberry Shield named MiniIOEx, you can easily monitor the battery and Raspberry Pi supply voltage. An external cable connection is not required. The 12Bit Analog Input sensor on the MiniIOEx is also connected to the 24V and 5V line. The power block on the MiniIOEx converts the voltage from 5V to 30V to 5V. Therefore, you can also supply the MiniIOEx with 12V battery voltage instead of 24V.”
