What it does

The Touch Sensor module detects human touch through capacitive sensing, even through thin insulating materials. It provides a digital output when touch is detected, making it ideal for touch switches and interactive panels.

Key features

Capacitive touch detection
Works through insulation
Digital output
Adjustable sensitivity
Low power
3.3V-5V operation
LED indicator

Good to know

Sensitivity affected by material thickness between sensor and finger
May trigger falsely in high humidity
Keep away from large metal surfaces
Use pull-up/pull-down as needed
