Module with 3 QTRX type optocoupler with RC (digital) output. The module operates from 2.9 V to 5.5 V, detects objects at a distance of up to 30 mm. The sensor will be used in projects that require detection of changes in the ground, e.g. in linefollower robots. Pololu 4303

Adafruit 2267 - Bluefruit LE Friend - Bluetooth Low Energy (BLE 4.0) - nRF51822

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
