QTR-8A Reflectance Sensor Array
SKU: POLOLU-960| Brand: Pololu AustraliaThis 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. Learn More$12.51 AUD, inc GSTAUD, inc GSTdelivered by
