Optical Sensors

Optical biometric sensor for fast fingerprint identification and verification in embedded projects, ideal for access control, time attendance or smart locks. Integrates sensor, DSP and FLASH memory in an all-in-one solution, stores up to 300 fingerprints, has 500 DPI resolution and finger presence detection. Easily connects via UART TTL or USB 2.0, operates at 3.3-5V.

The IR reflective sensor module is ideal for line tracking and black and white contrast detection in robotics projects. It integrates an IR LED and a phototransistor with on-board conditioning for digital output DO, operates at 5V and connects quickly via a 3-pin header. The compact dimensions and mounting hole make it easy to mount, optimal for small distances up to 3 mm.

TCRT5000 3-sensor IR module for detecting black lines on light backgrounds, ideal for line-following robots and Arduino projects. Provides 3 separate digital outputs L, C, R for left, center, right positioning and fast direction corrections. Operates at 5V, has integrated comparators for stable signal and status LEDs for quick verification.

Module for precise color detection and light intensity, ideal for sorting, LED calibration, or surface analysis. It offers simultaneous measurement on RGB plus clear channels with 16-bit ADC, includes an IR filter for stable results under varying light, communicates simply via I2C at address 0x29, and operates at 3.3V or 5V with low power consumption.

IR photoelectric sensor for proximity detection in industrial applications, operates by diffuse reflection without a reflector, wide 6-36V DC supply for easy integration with PLCs and microcontrollers. It offers a 3-wire PNP NC output, adjustable distance up to 30 cm and fast 2 ms response, M18 housing with IP67 protection and status LED for quick verification.
