IR distance Click carries Sharp’s GP2Y0A60SZ0F distance measuring sensor, which comprises of an integrated PSD (position sensitive detector), an infrared LED and a signal processing circuit. The measuring range is between 10 and 150 cm. The Click is designed to run on either 3.3V or 5V power supply. It communicates with the target MCU over RST and AN pin on the mikroBUS™ line.
The sensor on IR distance Click is not easily influenced by variations caused by the reflectivity of the object whose distance is measured (it won’t be able, however, to detect the distance of a mirror). For optimal operation the lens should be kept clean, because dust, water or oil on its surface can impact the precision of the sensor.
With these precautions in mind, the IR distance can be used for designing touch-less switches, various energy-saving devices, but it’s also suitable for robotics.
The Click board™ outputs an analog voltage corresponding to the distance of the object (through the mikroBUS™ AN pin). An Enable (EN) pin is also utilized.
IR distance Click features an SMD jumper (zero ohm resistor) that let’s you switch between a 3.3V or a 5V power supply.
