IR distance sensor includes cable (20cm-150cm) (GP2Y0A02YK) CamJam The ADXL335 is the latest

The ADXL335 is the latest and greatest from analogue devices

Optional user pushbutton on pin 12

Because the sensing distance is up to 5cm you can mount Skywriter HAT behind a sheet of non-conductive material (like acrylic or fabric) and completely hide it inside your project

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

IR distance sensor includes cable (20cm-150cm) (GP2Y0A02YK) CamJam The ADXL335 is the latestThe 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
