    Hardware Features

    This sensor takes a continuous distance reading and reports the distance as an analog voltage with a distance range of 20cm (~8") to 150cm (~60"). The interface is 3-wire with power, ground and the output voltage and requires a JST 3-pin connector (not included). The JST 3-pin connector includes the J3 connector for the sensor and bare wires at the other end, and requires that the processor or ADC-side connector be purchased or built separately. For most applications we recommend purchasing the Sharp IR to Servo Cable separately.
