Infrared IR Proximity Sensor (10-80mm)

Ultrasonic distance sensor (sonar) with a measuring range from 30 cm to 5 m. It allows you to read data via the USB interface. DFRobot SEN0270

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 holes for a 2.54 mm connector and an indicator LED. Its color, transparency, and light-sensitive properties make it ideal for robotics, automation, and contactless interfaces. Pololu 5562

ToF VL53L0X distance sensor module designed for M5Stack sets. It allows you to measure distances up to 2 m and communicates via the I2C interface. M5Stack U072

Suitable for outdoor applications such as car reversing sensors, security alarms, industrial inspection, etc. SEN0207

This sensor is a carrier/breakout board for ST’s VL53L0X laser-ranging sensor, which measures the range to a target object up to 2 m away.

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

A miniature lidar proximity sensor that detects objects up to 10 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 5462

Module with a digital distance sensor with a range of up to 15 cm. It has a digital output that goes low when an object is detected. Pololu 4054
