Metal touch sensor module is a type of switch that only operates when it’s touched by a charged body. It has a high-frequency transistor that can conduct electricity when receiving electromagnetic signals. The Metal Touch Sensor Module utilizes a floating lead on a Darlington transistor to detect a touch. The module is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the output of the module is low, lower power consumption; When a finger touches the corresponding position, the output of the module is high, if not touched for 12 seconds, it switches to low-power mode. Jog type: the initial state is lower, higher touch, do not touch is lower. This Module can be installed in such as surface plastic, glass of non-metallic materials. In addition to the thin paper (non-metallic) covering the surface of the module, as long as the correct location of the touch, you can make it hidden in the walls, desktops, and other parts of buttons. Features: Low-level output signal used for human body touch sensor alarm Low power consumption. Can replace the traditional touch of a button. Single-channel signal output Adjustable sensitivity Four M2 screws positioning holes for easy installation. Applications : Touch-based Switches: Used in smart home systems for touch-sensitive lighting or devices. Security Systems: Trigger alarms or alerts based on human touch detection. Human Interface Devices: Integrate into touch panels or kiosks for user interaction. Appliance Control: Enable touch control in household appliances like fans, lights, or thermostats.
