TTP223B Capacitive Touch Switch Module hiBCTR 10pcs 2-5.5V M2 Mount

Description

Product Overview

The hiBCTR TTP223B capacitive touch switch module is engineered for reliable, instant touch detection across a wide range of DIY and professional applications. Built around the proven TTP223B chip, each module reacts within 60 milliseconds, delivering a seamless on/off experience that feels natural to the user. The module operates on a flexible voltage range of 2 to 5.5 volts, making it compatible with common microcontroller platforms such as Arduino, Raspberry Pi, ESP32, and many others. Its ultra‑low power consumption—under 1.5 µA in standby—ensures that battery‑operated devices can run for months or even years without frequent recharging.

Physically, the module measures 24 × 24 × 7.2 mm and includes four M2‑size mounting holes that allow secure attachment to a variety of non‑metallic surfaces, including glass, acrylic, wood, and paper up to three millimeters thick. The PCB is coated with a protective lacquer that guards against moisture and dust, extending the lifespan of the sensor in harsh environments. The module’s TTL‑compatible output (0.8 V high / 0.3 V low) simplifies integration with digital logic circuits, eliminating the need for additional level‑shifting components.

Each package contains ten identical modules, providing a cost‑effective solution for projects that require multiple touch points, such as stair lighting arrays, interactive smart mirrors, capacitive control panels, and multi‑zone lighting systems. The modules are tested to meet the specifications listed in the product data sheet, and they carry the hiBCTR brand assurance for quality and consistency.

Usage

These modules excel in environments where traditional mechanical switches are impractical or where a sleek, invisible interface is desired. Install the sensor behind a glass panel to create a touch‑activated lamp switch that blends seamlessly with modern interior design. In a smart home setting, the modules can be wired to control LED strips, fans, or relays, enabling voice‑controlled or app‑controlled operation without visible buttons.

For hobbyists and makers, the low voltage requirement means the modules can be powered directly from a 3.3 V or 5 V rail, reducing the need for additional voltage regulators. Their low standby current makes them ideal for battery‑powered IoT devices such as remote sensors, wearable gadgets, and portable controllers. The M2 mounting holes allow the sensor to be fixed onto custom‑fabricated enclosures, 3D‑printed housings, or existing panels, providing flexibility in mechanical design.

Because the sensor detects capacitance changes through non‑metallic materials, it can be placed behind a thin layer of wood, plastic, or even paper, enabling hidden touch controls on furniture, appliance panels, and decorative objects. The fast response time ensures that user interactions feel instantaneous, which is critical for applications like interactive art installations or responsive lighting displays.

FAQ

Can the module detect touch through glass?

Yes, the TTP223B sensor can sense touch through non‑metallic materials such as glass, acrylic, or plastic up to three millimeters thick, making it ideal for hidden or aesthetic installations.

What is the maximum current the output can source?

The module’s TTL output can safely source up to 10 mA, which is sufficient to drive most LED indicators or to interface with a transistor or relay driver circuit.

How long does it take to wake from standby mode?

The sensor wakes in approximately 220 ms after detecting a touch, providing a quick transition from low‑power standby to active operation.

Is the module compatible with 3.3 V logic?

Absolutely. The module operates from 2 V to 5.5 V and its output levels are TTL compatible, so it works directly with 3.3 V microcontroller pins without additional level shifting.

Can I use the modules in a multi‑touch array?

Each module functions independently, so you can connect multiple units in parallel or series to create multi‑touch panels, provided each is wired to its own input pin on the controller.
