Touch sensitive capacitive button on the TTP223B microcircuit with a MOSFET switch for controlling low-voltage loads.
The operating principle of this touch button is based on the electrical capacity of the human body. The module is triggered for switching by touching the touch sensor with a finger. At rest - the output of the module is a low voltage level, when the sensor is touched, a high voltage level appears. After 12 seconds of inactivity, the module enters a low power mode.
Very low current consumption together with the reduced consumption mode allows the module to be used in self-powered systems.
The module can be mounted on plastic, glass or any other non-metallic surfaces. The sensor's sensitivity allows it to be mounted behind thin surfaces, which is very convenient for using it as hidden buttons.
Key Features:
Supply voltage: 6-28 V DC
Maximum switching current: 3 A
Standby consumption: 6mA
Board dimensions: 24 * 32 * 5
Modifications:
Jumpers S1/S2. Jumper S1 is installed as standard, the button operates in the "latching button" mode. To change the mode to "push button", unsolder the jumper resistor from position S1 and solder in place S2.
Capacitor C1. There is no capacitor as standard, the sensitivity is maximum. Solder the capacitor down to 20pF to reduce sensitivity. The higher the capacitance, the lower the sensitivity.
