The Square Capacitive Fingerprint Sensor Module is a compact biometric fingerprint recognition module that integrates a capacitive fingerprint sensor with an internal fingerprint processing algorithm. It communicates with a host microcontroller through a UART TTL interface and supports fingerprint enrollment, template storage, fingerprint matching, and identification. Its compact square form factor and low-power design make it suitable for embedded security and biometric applications. The module is designed for easy integration with microcontrollers and electronic control systems where fingerprint authentication is required.

• Can detect non-luminous object color.
• Dimensions: 32 x 24 x 20 mm (LxWxH)

• Operating Voltage: 3.3V
• Supply Voltage: 3.3V-5V
• The TCS3472 device provides digital return values for red, green, blue (RGB) and bright light sensing
• Color management is more accurate.
• The high sensitivity.
• Wide dynamic range.
• IR shading filters make the TCS3472 ideal.

• Max.sensitivity : 570nm.
• Semi sensitivity angle: +/-60degree.
• Although the device is very sensitive to ambient light, it suppresses the infrared (IR) spectrum, providing a higher visible spectral responsiveness similar to the “human eye.”
• It’s brand new, good quality & high performance.
• Sensitive to visible light only, no additional filters, good linear output.
