Sensor De Corriente ± 30a Efecto Hall Acs712 Arduino
Se trata de un pequeño sensor que mide la corriente utilizando el efecto Hall, y nos devuelve un valor de tensión entre 0V y 5V, proporcional a la intensidad que circula.
Se trata de un pequeño sensor que mide la corriente utilizando el efecto Hall y nos devuelve un valor de tensión entre 0V y 5V, proporcional a la intensidad que circula.
La corriente que desea medirse, genera un campo magnético que el sensor convierte en un voltaje proporcional en su salida, utilizando el efecto Hall. Este voltaje a su vez es leído por un sistema microcontrolador a través de un convertidor A/D para obtener su valor pico y mediante operaciones aritméticas calcular el valor RMS de la corriente de carga.
Características
- Sensor lineal de efecto hall de bajo offset.
- Alta precisión de medida debido a la cercanía del sensor de efecto hall al elemento de paso (ambos se encuentran dentro del IC).
- Baja resistencia del elemento de paso para una baja disipación de potencia (1.2 mΩ típico)
- Capacidad de sobrevivir a picos de corriente de hasta 5 veces la corriente nominal de operación.
- Las terminales del elemento conductor se encuentran aisladas electricamente (Hasta 2.1KV) por lo que evita la necesidad de aislamiento externo (optoacopladores).
Especificaciones técnicas
- Voltaje de salida: Analog output 66mV / A
- Voltaje de operación: 4.5V ~ 5.5V
- Salida de voltaje sin corriente: VCC / 2
- Dimensiones PCB: 31 (mm) x14 (mm)
- 5 μs output rise tiempo en respuesta a step input current
- Ancho de banda 80 kHz
- Error Total Salida: 1.5% at TA = 25°C
- Resistencia interna: 1.2 mΩ
- Mínimo voltaje de aislamiento entre pines 1-4 a pines 5-8: 2.1 kVRMS
- Sensitividad de salida: 66 to 185 mV/A
