Sharp GP2Y0A41SK0F Analog Distance Sensor 4-30cm

Model No: ROB-00178

TK. 1347.23

TK. 1095.01


Category: Robotics Sensor

Supplier: Pololu, USA

The 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 to most microcontrollers is straightforward: the single analog output can be connected to an analog-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 4 cm to 30 cm (1.5″ to 12″).

The GP2Y0A41 uses a 3-pin JST PH connector that works with pololu's 3-pin JST PH cables for Sharp distance sensors (not included). These cables have 3-pin JST connectors on one end and are available with pre-crimped male pinspre-crimped female pins, and with unterminated wires on the other end. It is also possible to solder three wires to the sensor where the connector pins are mounted (see the lower picture to the right). When looking at the back, the three connections from left to right are power, ground, and the output signal.

Pololu also carries an assortment of mounting brackets designed specifically for this sensor.
