QTR-8A Reflectance Sensor ArrayThis sensor module has 8 IR LED/phototransistor pairs mounted on a 0.375" pitch, making it a great detector for a line-following robot. Pairs of LEDs are arranged in series to halve current consumption, and a MOSFET allows the LEDs to be turned off for additional sensing or power-savings options. Each sensor provides a separate analog voltage output. |

Elenco AK-510 motion detector kitLearn about electronic motion detectors with this deluxe kit that includes a high-quality enclosure with a mounting bracket. The motion detector makes a loud, doorbell-like “ding-dong” sound when it detects motion. The kit is based on a pyroelectric infrared (PIR) sensor, which is a unique sensor that you can use to give your projects the ability to react to your presence. |
