ZMPT101B AC Voltage Sensor is the best for quick DIY projects, where we need to measure accurate AC voltages quickly and easily. It is a plug and play sensor and requires no external circuitry to measure AC Voltages. This is an ideal choice to measure the AC voltage using Arduino/ESP8266/Raspberry Pi boards. It offers basic safety requirements like High galvanic isolation, Wide Range, High accuracy, Good Consistency, etc

The most easiest way to measure an AC signal is using a resistor divier, but it is not safe as the high voltage that is being measured can be transferred to the microcontroller during malfunctions. It is always advisable to add an isolation transformer between the high voltage being measured and the microcontroller. This module does exactly that and provides safe isolation allowing you to measure high voltage AC loads. The output is a 0 to 5V analog signal that corresponds to the measured voltage. This sensor moduels included the transformer, input/output resistors for current limiting, opamp circuit for signal amplification, etc.
