QTR-8RC Reflectance Sensor Array SF_Biometrics 3 - 5v and the

3 - 5v and the module draws a nominal 18mA of current

this input module adds sixteen active-high digital inputs using just one port on your VINT Hub

Altimeter and temperature

You can improve sensing system accuracy for low-frequency sensing applications by adding a capacitor in parallel with the integrated 1 nF capacitor across the pads marked “filter” on the bottom silkscreen (this capacitor is labeled C2b in the schematic below)

QTR-8RC Reflectance Sensor Array SF_Biometrics 3 - 5v and theThis 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 digital I O measurable output . Note: The QTR 8RC reflectance sensor array requires digital I O lines to take readings. The
