I'm working on a project where I'm repurposing sensors from a Pop-a-shot machine
Sensors we're using https://www.popashot.net/shop/accessories/scoring-sensors/
The sensors are a 4 pin reflective IR sensor.
The 4 pins are ground, power, transmitting (tx), and receiving (rx). The transmitting is for lighting the led and receiving is for when the sensor receives a signal.
They worked perfectly before we connected them to the Pi
We are able to get the sensor working with the PI and are able to read inputs.
The issue we are having is that instead of being able to sense objects nearly 12 cm away, it is only working when you are waving your hand 2-3 cm from the sensor.
Is there something that can be done to increase the sensitivity? We are pretty sure that we have it connected to the GPIO pins correctly. We have the transmitting connected to power, ground connected to ground, power connected to power and the receiving connected to the gpio pin.
We aren't sure if the sensor isn't sensitive enough, or if the led isn't powerful enough
We've tried the 5v and 3v3 pins for power, Same results.
