IR distance sensor includes cable (20cm-150cm) (GP2Y0A02YK) CamJam It attaches to the Raspberry

It attaches to the Raspberry Pi by way of one of the small sockets on the board's upper surface

Lithium protection mode

such as miniature TVs

which is useful when multiple devices need to be dimmed or blinked together using software control

We have a great tutorial in the Adafruit Learning System with documentation and example code

IR distance sensor includes cable (20cm-150cm) (GP2Y0A02YK) CamJam It attaches to the RaspberryThe Sharp IR Distance Sensor (20 150 cm) measures how far away an object is by detecting reflected infrared light and outputs an analogue voltage that can be read by a microcontroller. This SHARP distance sensor bounces IR off objects to determine how far away they are. It returns an analogue voltage that can be used to determine how close the nearest object is. Comes with 8" long 3 JST interface wire. These sensors are good for detection between 20cm
