The Product works as it is said in the description: It does not give you speed (speed calculations have to be done by the micro-controller) so the name "Speed Measuring Sensor" is a bit off. these modules could also be used as optical endstops for 3D printers

ok. lev og pris fin.

S&H OK. Item as described. Visual inspection shows no obvious damage. Product quality unknown at this point.

OK

The output of this board can oscillate when the slot in the wheel is half open - half closed. The designer added a 100nF capacitor across the photo transistor but that makes the situation worse. To fix this problem, the capacitor closest to the edge of the board should be removed and a 33k resistor must be added between output (pin7) and the non-inverting input (pin5). I will post the schematic in a second. Note: if you poll the output in your software, you can omit the modification. But if you

Justamente andaba buscando este montaje para hacerme un encoder óptico. Ya lo he montado y va fenomenal. Las señales en el osciloscopio perfectas y utilizando 2 módulos sobre el mismo disco perforado permite saber el sentido de giro y contar ó descontar pulsos acoplado a un Arduino por ejemplo.

Todo esta perfectamente como se indica y ademas tiene buena cálida, muy contento con este producto. Real mente merece la pena la relación precio calidad lo recomiendo. Ok

Está a funcionar! Os motores estão em paralelo para cada lado (direito – esquerdo). É melhor utilizar as rotinas de interrup :-) Só falta descobrir como aplicar a realimentação para Controlo de Velocidade e distância LOL
