Description:
Sharp distance sensors are a popular choice for many projects that require accurate distance measurements. This IR sensor is more economical than sonar rangefinders, yet it provides much better performance than other IR alternatives. Interfacing with most microcontrollers is straightforward: the single analogue output can be connected to an analogue-to-digital converter for taking distance measurements, or the output can be connected to a comparator for threshold detection. The detection range of this version is approximately 20 cm to 150 cm (8″ to 60″).
The GP2Y0A02 uses a 3-pin JST PH connector that works with our 3-pin JST PH cables for Sharp distance sensors (not included); the top picture on the right shows a shorter-range Sharp analogue distance sensor with one of these cables. These cables have 3-pin JST connectors on one end and are available with pre-crimped male pins, pre-crimped female pins, and with unterminated wires on the other end.
Specification:
- Operating voltage: 4.5 V to 5.5 V
- Average current consumption: 33 mA (note: this sensor draws current in large, short bursts, and the manufacturer recommends putting a 10 µF capacitor or larger across power and ground close to the sensor to stabilize the power supply line)
- Distance measuring range: 20 cm to 150 cm (8″ to 60″)
- Output type: analogue voltage
- Output voltage differential over distance range: 2.05 V (typical)
- Update period: 38 ± 10 ms
