The ACS712ELCTR-30A is a Hall-effect-based linear current sensor module designed for accurate measurement of both AC and DC currents up to ±30A. Utilizing Allegro Microsystems' ACS712 IC, this module provides a ratiometric analog voltage output proportional to the measured current, making it ideal for applications requiring precise current sensing

The ACS712ELCTR-5A Module is a highly accurate current sensor designed to measure AC and DC currents up to ±5 Amps. Built around Allegro’s ACS712 Hall Effect IC, this module provides an analog voltage output that is linearly proportional to the current passing through it. The output voltage is centered at 2.5V when no current is flowing, allowing it to measure both positive and negative currents.

ESP-07 ESP8266 Serial WiFi Module is packaged in SMD, through the standard SMT equipment to achieve rapid production of products, to provide with high reliability of the connection, especially for automation, large-scale, low-cost modern production methods, It’s suitable for all kinds of Internet of things hardware terminal occasion. 

The SCT-013-015 is a split-core current transformer designed for non-invasive AC current measurement. It provides a 1V RMS output at 15A RMS input, making it suitable for interfacing with microcontrollers, energy monitoring systems, and protection circuits. Its compact design and ease of installation make it ideal for applications such as monitoring AC motors, lighting equipment, and air compressors
