Single touch sensor TTP223 - When the marked field is touched, the module provides high level to SIG pin. As a standard, we have a low level (no touch detected). It can be used as a physical contact detector, low energy consumption. Specification: - Power supply 2 - 5.5V DC - The chip used: TTP223 - Response time: 60ms - LED indicator - touch signaling - The sensitivity of the sensor depends on the capacitance value C1, the lower the value, the greater the module sensitivity - PCB board dimensions: 14mm x 11mm https://elecena.pl/product/22605126/ttp223-14x11mm-miniature-touch-sensor-arduino 2023-02-22 https://elecena.pl/product/22605126/ttp223-14x11mm-miniature-touch-sensor-arduino 2024-03-11 https://elecena.pl/product/22605126/ttp223-14x11mm-miniature-touch-sensor-arduino 2025-10-25 https://elecena.pl/product/22605126/ttp223-14x11mm-miniature-touch-sensor-arduino 2025-10-29
