Using the Raspberry Pi as a Simple Current and Power Meter
The Raspberry Pi provides general purpose digital input/output pins (called GPIO pins) that you can use for reading digital logic signals or for outputting digital logic levels. These are 3. 3 volt logic pins. A voltage near 3. 3 V is interpreted as a logic one while a voltage near zero volts is a logic zero. -cloud motor-control panel

Data Loggers. Data Logging is the recording of collected data over a period of time. Depending on the application, the data can be temperature measurements, voltages, current, humidity, or other signals of interest. Voltage measurement DAQ HAT for Raspberry Pi10 V inputs and sample rates up to 100 kS/s, optimized for single

The original post argued that the measurement data indicated that the gpio, when operated as inputs, were probably 5V safe. The only conclusion I can come up with is that the Raspberry Pi GPIO inputs are 5 Volt safe, and that there is some kind of protection which kicks in around 5. 8 Volts. Raspberry Pi GPIO: mixing voltage levels; An
Remotely Monitor Temperature with Raspberry Pi - Make
Raspberry Pi battery monitor. This project monitors the voltage and, indirectly, charge status of a 12 volt lead-acid battery, e. g. a car starter battery or a marine deep-cycle battery.
Using the raspberry pi to measure multiple electrical circuits
A logic level converter is included on the ADC Pi board giving you a buffered 5V i2c port making it easy to add other I2C devices which operate at 5 volts without damaging the raspberry pi 3. 3 volt i2c port.
