The Analog Infra-Red Rangefinding System (AIRRS) is a efficient analog range detection sensor based on the Sharp GP2D12.

Description [Hide]

This item has been discontinued and replaced by Sharp GP2Y0A02YK.

The Analog Infra-Red Range Finding System (AIRRS) is a compact, fully-integrated IR range-finding system in a small, inexpensive package. The AIRRS is Ideal for mobile robot navigation, positioning, distance & speed measurement.

The AIRRS works by emitting an infra-red beam and watching for its reflection. The further away the object is from the sensor the long its reflection takes to reach the sensor and the lower the output voltage. The typical voltage range for an AIRRS is from 0V for an object at 80cm to 2.5V for an object at 10cm.

The AIRRS sensor is an analog sensor, in order to use this product with a microcontroller you must have an available Analog-to-Digital Converter in your micro or use an external A/D converter. Using a comparator will allow the AIRRS to be set as a threshold detector.

Applications include, obstacle avoidance, target acquisition, measuring distance, positioning and robot navigation.

  • Inexpensive (about 1/3 the price of Ultrasonics)
  • Simple to Use
  • Small (4.5 x 1.5 x 1.9 cm)
  • Connects directly to any microcontroller with A/D
  • Detection range: 10 cm to 80 cm (4" to 31")
  • Low microprocessor overhead (uses only 1 I/O line and a few lines of code)
  • Highly tolerant of ambient light and IR interference
  • Nearly immune to variations in object color and reflectivity

Each Kit includes

  • 1 Sharp GP2D12 Sensor
  • 1 pre-assembled 12" cable
