Descripción
Sensor IR reflexivo
Viene con una resistencia de 470 ohm
Sensor fácil de usar y fácil de soldar
El mejor rango de trabajo: 2 mm a 10 mm
El Sensor IR Reflectivo con Resistencias de 470 y 10K es una carcasa de plástico simple con dos elementos: un LED IR y un fototransistor IR. Puede controlar el LED IR y encenderlo para rebotar luz Infrarroja de objetos para determinar su reflectividad. Las cosas blancas y de colores claros harán rebotar la luz, para que puedas detectarla. Las cosas negras y de color oscuro absorberán la luz IR para que no se detecte. Del mismo modo, si algo no interfiere con el sensor, tampoco se activará. Viene con una resistencia de 470 ohmios y una resistencia de 10K que puede usar como resistencia pull-up para el fototransistor. El sensor es compatible con placas de pruebas y es fácil de soldar. El sensor funciona mejor cuando se detecta un objeto de color claro a aproximadamente 5 mm de distancia; 2 mm a 10 mm funcionó bastante bien, pero los resultados pueden variar con el brillo del LED, el brillo del objeto, etc.
Tamaño: 15 mm x 18 mm x 5 mm / (0.6 "x 0.7" x 0.2 ")
I received this in quick time. It was good that the vendor supplied the resistors for the reference config. I should have paid more attention. 2 - 10mm range was too short for my obstacle detection application. Particularly as my bot would cover that distance in a very short time. Giving little time to take action on obstacle detection.
