QTR-1RC Reflectance Sensor

Help & Support Robot Parts

Hi everyone !

I wanted to know what is the QTR-1RC Reflectance Sensor output voltage ? Is it the same as the supply (5v) ?

Will it work with a 3.3v supply voltage ? I use a esp32 and the I/O pins need 3.3v.

Furthermore, does anyone have the footprint of the sensor ? I want to buy one and embed it directly in my pcb.

Thank you,
Victor.

It seems that the sensor works on 5V and the supplier is not giving more specs than that.

See interesting note on page 2 of the documentation: https://www.robotshop.com/media/files/pdf/pololu-qtr-reflectance-sensor-application-note.pdf

Here I could find the dimension but no footprint:
Size: 0.3’’ x 0.5’’ x 0.1’’
Weight: 0.2g
