The A88 Metal Detector Non-Contact Metal Induction Detection Module operates by inducing currents in metal objects, triggering a response upon detection. Equipped with an onboard buzzer, it provides audible signals when it detects metal, while an integrated potentiometer allows for sensitivity adjustment. Soldering the power cables onto the module is necessary for functionality, with positive connection to the module’s exterior and negative connection between the potentiometer and an electrolytic capacitor.

This module, designed specifically for metal detection, offers reliability and ease of use. By inducing currents in nearby metal objects, it effectively alerts users with its buzzer when metal is detected. The inclusion of a potentiometer enables fine-tuning of sensitivity, allowing for customized detection settings. With its compact dimensions and lightweight construction, this module offers convenience and versatility for various metal detection applications. Additionally, its technical specifications, including a working voltage of 5V DC and a detector distance of 1cm, ensure reliable performance in diverse environments.
