A88 metal detector module
A88 metal detector module with adjustable sensitivity and digital output—perfect for DIY metal detection, security systems, and electronics projects.
The A88 Metal Detector Module is a compact and easy-to-use sensor designed for detecting metal objects. It outputs a digital signal when a metal object is detected, making it suitable for interfacing with microcontrollers such as Arduino, ESP32, ESP8266, and Raspberry Pi.
The module features adjustable sensitivity via a potentiometer, allowing precise tuning for different detection ranges and types of metal. It is widely used in security systems, DIY metal detectors, robotics, industrial automation, and educational electronics projects.
With its small form factor, low power consumption, and reliable performance, the A88 module is ideal for both hobbyists and professional electronics applications.
