Digital IR Proximity Sensor - distance sensor (400cm)

An ultrasonic sensor whose operation is based on the time-of-flight (ToF) principle. In addition to distance information, the sensor also generates an echo energy intensity value useful for distinguishing between different materials or surfaces. Seeed Studio 101021097

This sensor is a carrier/breakout board for ST’s VL6180X proximity and ambient light sensor, which measures the range to a target object up to 20 cm away (or 60 cm with reduced resolution). Pololu 2489

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

A miniature lidar proximity sensor that detects objects in the range of 1 mm to 300 cm by generating a PWM signal proportional to distance. It operates in the 3-5.5 V range, draws 30 mA, features an ENABLE pin for sleep mode, a 3-pin JST SH connector, and an indicator LED. Its resistance to color, transparency, and lighting makes it ideal for robotics, automation, and contactless interfaces. Pololu 5493

The GP2Y0A60SZ offers a wide detection range of 4″ to 60″ (10cm to 150cm) and a high update rate of 60Hz. The distance is indicated by analog voltage - only a single analog input is required to interface with the module. Pololu 2476

The GP2Y0A41SK0F sensor performs precise distance measurement in the range of 4–30 cm with an analog output signal adapted for operation with microcontrollers. It is used in robotics projects, obstacle avoidance systems, and automation devices detecting the presence of objects.
