Reading Battery Voltage To perform analog measurement by default Arduino uses its power supply as a voltage reference. If we did not change this setup when reading the battery voltage it would always be the same as our power supply will get lower with the discharging battery. To solve this we...

The DHT effect, a feature that allows for a stable and consistent reading, is particularly useful in applications where environmental conditions can fluctuate. **Adaptive Scenarios and Advanced Control** With the ability to read voltage and support Arduino temperature control PID, these sensors are ...
Programmable calibration values, conversion times and averaging combined with an internal multiplier allow direct reading of current in amperes and power in watts. The INA226 senses the current on the common-mode bus voltage, which can vary from 0 V to 36 V, independent of the supply voltage....

The Arduino Voltage reference: What if you need to know the voltage value of your supply? Ok you say. Fine, I'll just measure it with the ADC. The trouble is you get the same reading of 1023 whatever the supply is set to! The ADC is ratiometric - it's not an absolute measurement...
