What are Current and Voltage Sensors?
Current and Voltage Sensors are electronic modules that measure electrical parameters in a running circuit and output a proportional analog or digital signal to a microcontroller. Current sensors detect how much current flows through a conductor without breaking the circuit. Voltage sensor modules use resistive dividers to scale high voltages down to safe readable levels. A common example in Indian engineering projects is using the ACS712 current sensor to monitor battery discharge rates in a solar energy system.

How to Choose the Right Current and Voltage Sensors
Choose the sensor based on the type of electrical parameter and measurement range your project needs. For DC battery monitoring up to 25V, a simple dc voltage sensor module works directly with Arduino analog input. For AC mains voltage measurement, ZMPT101B is the safe and accurate choice as it provides isolation from the mains. For current measurement, ACS712 suits both AC and DC applications up to 30A. One practical tip: always check the sensor's output voltage range against your microcontroller's ADC reference voltage before connecting, as an output higher than 3.3V can damage ESP32 ADC pins permanently.
