KY-036 Metal Touch Sensor Module KY036 KY-024

Product Overview

The module featured in your document is the KY-036 Metal-touch sensor module. It operates on the principle of relative measurement to output a signal whenever the front metal spike of the sensor unit is physically touched. The board features a front-facing sensing unit that forwards an analog signal to an onboard amplifier and a comparator circuit, which handle both the raw voltage scaling and the binary digital switching. It is highly popular in DIY robotics and microcontroller applications for proximity switches, human-machine interface touch triggers, and environmental boundary sensing.
