Description

TTP223 single touch sensor – Arduino touch sensor

Single touch sensor on TTP223 chip is a touch button module. The module sends a signal when the „TOUCH” button field is touched. When the button is touched, a signal is sent to the output and the LED built into the board lights up.

When touching a marked field on the PCB, the module sends a high state to the SIG pin. By default we have a low state (no touch detected).

Can be used as a physical contact detector, switch, keypad, etc…

Product features

• Low energy consumption.
• LED that indicates when the button is touched.
• Fast response time of about 60ms.
• For use in projects: Arduino, AVR, PIC, etc.

Technical data

• Power supply 2 – 5.5V DC
• Circuit used: TTP223
• Response time: 60ms
• Indicator LED
• Sensitivity of the sensor depends on the value of the capacitance C1, the lower the value the higher the sensitivity of the module
• PCB dimensions: 14mm x 11mm

Trigger setting mode: (1-> short, 0-> no short)

• AB = 00: high level TTL output without locking,
• AB = 01: self-locking high level TTL (state memory)
• AB = 10: low-level TTL output without locking,
• AB = 11: self-locking low-level TTL (state memory)

Included

• TTP223 single touch sensor – 1 pc.
