This module is based on a high precision ZMPT101B voltage Transformer. This module makes it easy to monitor AC mains voltage upto 250 volts. This module comes with Multi-turn trim pot which can be used for adjusting the Analog output.Using ZMPT101B AC Voltage Sensor you can easily measure main voltage using Arduino or even Raspberry Pi (external ADC required)
The 20A Range Current Sensor Module ACS712 consists of a precise, low-offset, linear Hall circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field in which the Hall IC converts into a proportional voltage.
This Wifi IOT Arduino Learning Kit provides an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It contains all of the essential components required to start programming with the Arduino Uno and Node MCU board.
