Line Detection Sensor

Dear All
One of my friend has 3pi robot which does not working properly. Se we checked the sensors and identifies that one sensor is defective. Please advice buy same type sensor

it would be much appreciated f you can provided ebay link

Thanks in advance


I am not sure how you determined that one of your sensors was bad, but one way to check is to run the “Sensors” option in the “3pi-demo-program” example located in the 3pi AVR libraries. The bar graph on the LCD corresponds to the sensors on the 3pi, and is a good way to test to see if an individual sensor is not responding properly. If you have not already, you might try this to verify which sensor is damaged and that there is only one.

You can use the Fairchild QRE1113GR as a generic replacement for your 3pi reflectance sensors.
