Descripción
Placa de sensor con un indicador LED de "encendido"
Detecta el nivel de sonido con un MEM (micrófono en un chip) y un preamplificador
Utiliza un termistor para medir la temperatura
Detección de nivel de luz con un fototransistor (0 a 1023)
Compatible con el Placa Programable BBC micro:bit (no incluido)
El Placa de Sensores para MICRO:BIT Monk Makes le permite detectar el nivel de sonido, la temperatura y el nivel de luz. El sensor para micro: bit usa un MEM (micrófono en un chip) y un preamplificador. La salida del sensor de sonido está conectada a una entrada analógica donde puede muestrearse. La señal de sonido varía alrededor del nivel de 1,5 V. Entonces, el silencio producirá una salida analógica de alrededor de 1,5 V.
Utiliza un termistor para medir la temperatura. La salida de temperatura de la placa es un voltaje que indica la temperatura. Esto se mide usando una entrada analógica en el micro: bit. Si quiere que sus temperaturas estén en Fahrenheit, multiplique la temperatura en grados C por 9, divida el resultado por 5 y luego agregue 32.
El sensor de luz utiliza un fototransistor para medir el nivel de luz y produce un voltaje de salida que aumenta a medida que aumenta el nivel de luz. Aquí hay una guía sobre el tipo de nivel de luz que puede obtener del sensor bajo diferentes condiciones (0 a 1023).
Oscuro 0 a 3
Habitación débilmente iluminada 6 a 10
En interiores directamente bajo una luz de 10 a 50
Al aire libre (día aburrido) de 100 a 200
Al aire libre (día soleado) 800 a 900
Aunque el valor máximo de lectura analógica es 1023, la lectura máxima de este sensor es de alrededor de 900.
The manufacturer is a little short with explanations. For the temperature they write that the temperature calculation is complicated, but gives no formulas, except one that is enough to get started. Would be nice with something a little more in-depth. Other than that a good product, I needed it for detecting sound. They mention subtracting 511 from the analog read, but no more. Would be nice with a little more explanation of the 511 for a beginner like me.
