Fc 51 Ir Sensor Datasheet _hot_
The ESP32 is a popular choice for IoT projects, and integration is simple.
Line following (can distinguish between black and white surfaces). Hand-wave switches or touchless triggers. Fc 51 Ir Sensor Datasheet
A: Not reliably. Glass reflects very little IR. It may detect the glass if the angle is steep, but generally, it is not suitable for transparent objects. The ESP32 is a popular choice for IoT
Turning the onboard potentiometer clockwise usually the detection range (making it more sensitive). Counterclockwise decreases the range. This works by changing the comparator's reference threshold. Fc 51 Ir Sensor Datasheet
