Infrared proximity sensor module - Waveshare 12224

Ultrasonic ToF sensor dedicated to the identification of materials at a distance of 2 to 10 cm. It can distinguish between hard and soft materials and transmits information via digital IO (high/low) or UART interface. DFRobot SEN0560

A miniature lidar distance sensor that detects objects up to 5 cm away, regardless of color, transparency, or lighting. It generates a digital signal (0 V on detection), operates in the 3-5.5 V range, draws only 30 mA, and supports sleep mode via the ENABLE pin. Ideal for robotics, automation, and contactless interfaces, it offers a fast response time (142 Hz), switching hysteresis, and a compact housing with an indicator LED. Pololu 5550

ST Microelectronics\' compact Time-of-Flight (TOF) sensor uses a 940 nm laser to precisely measure distances from 1 mm to 1.2 m with a resolution of 1 mm. It supports an I²C interface, has an XSHUT input for shutdown and a GPIO1 output for object detection, and is compatible with voltages from 2.6 to 5.5 V thanks to a built-in regulator and logic level converter. Pololu 3692

Laser distance sensor with a range of 5 cm to 15 m. It has a high accuracy of ± 2 cm and a resolution of 1 mm. DFRobot SEN0524

A miniature lidar proximity sensor that detects objects ranging from less than 1 mm to 50 cm by generating a PWM signal proportional to distance. It operates in a 3-5.5 V range, draws 30 mA, features an ENABLE pin for sleep mode, and a 3-pin JST SH connector and indicator LED. Its color, transparency, and light-sensitive nature make it ideal for robotics, automation, and contactless interfaces. Pololu 5472
