The KY-036 Metal Touch Sensor Module uses an LM393 comparator IC on a 4.3 x 1.6 x 1.5cm board, providing both analog (AO) and digital (DO) outputs through a 4-pin connector, operating from 3.3V to 5V. This touch sensor’s LM393 comparator takes the raw body-conductivity signal from the metal contact point and processes it into two simultaneously available outputs suited for different use cases depending on what the project needs from a touch event.
The ky 036 touch sensor module’s AO pin outputs a graduated analog voltage reflecting the strength of the touch signal — useful when a project reads this through an Arduino analog pin to detect near-contact or vary response based on touch firmness, while the DO pin gives a simple threshold-crossed HIGH/LOW trigger for straightforward digital reading. This arduino ky 036 module’s elongated 4.3cm form factor fits neatly alongside a breadboard column or inside a small project enclosure where compact linear boards are easier to route than square modules.
this ky 036 metal touch sensor depends on body conductivity rather than a dedicated capacitive chip, its sensitivity and reliability can vary noticeably between different users based on individual skin moisture, requiring code-side calibration if consistent threshold behavior across multiple people matters. Available from StemVolt, this module is ideal for students, hobbyists, and makers building orientation-independent systems and standalone electronics projects.
