SHARP IR Range Finder

Description. • Infrared range finder 10cm (~4") to 80cm (~30") ... The Sharp GP2Y0A21YK0F IR Range Sensor - 10cm to 80cm takes a continuous distance reading and reports the distance as an analog voltage with a distance range of 10cm (~4") to 80cm (~30"). The interface is 3-wire with power, ground and output. Source: RobotShop


Extra ideas for math classes

Have the students figure out the speed of the chip + the speed of the sensor and the round-trip time of flight from the IR sensor to the target. (Time of Flight = FlightTime/2) They already know the distance from the sensor to the target as a reference. Looking up data sheets online and digging out the info and doing the math makes for a middle-school level of research (reverse enginnering.)

Then have them alter their programs to use constants for the sensor.
