Tablero de alta precisión que utiliza el ACS723 para AC y DC moderados
Mide las corrientes de CC y CA hasta 5A
El sensor ACS723 usa un sensor de efecto Hall para generar un voltaje
El Sensor Adaptador de Corriente SparkFun - ACS723 (Corriente Baja) es una placa de alta precisión que utiliza el ACS723 para aplicaciones moderadas de detección de corriente de AC y DC. El sensor ACS723 usa un sensor de efecto Hall para emitir un voltaje relativo a la corriente que fluye a través de los pines IP+ e IP- de la placa. La ventaja de usar un sensor de efecto Hall, específicamente, es que el circuito detectado y el circuito que lee el sensor están eléctricamente aislados, lo que significa que, aunque su Arduino funciona con 5V, ¡el circuito detectado puede funcionar a voltajes DC o AC más altos!
El Sensor Adaptador de Corriente SparkFun - ACS723 (Corriente Baja) mide las corrientes de DC y AC hasta 5A, tiene un aislamiento eléctrico completo de los circuitos medidos y detectados, y tiene una sensibilidad base de 400mV/A. Aunque la salida analógica es ajustable a 80 kHz, el ancho de banda en el filtro de ancho de separación del sensor ACS723 se ha establecido en 20 kHz para reducir el ruido cuando se utiliza a altas ganancias. El ancho de banda completo de 80 KHz que puede captar el sensor se puede recuperar cerrando el puente JP1 (selección de ancho de banda) en la parte posterior del tablero.

The ASC723 current sensor is easy to use. In testing, the ASC723 current sensor showed good results. Its sensitivity of 400 mV / A offers better reading accuracy. The stability of its power supply (5Vdc) indicates that it has a great influence on the accuracy of current readings. Pay attention to magnetic sources near the current sensor. These could influence the readings. After one hour of use under a load of 5A, the temperature of the ACS723 is not significant. The ACS723 is a current sensor Interesting to discover ...

Low current sensor
I have had no luck with other analog current sensors that measure 20A or higher. The output level is highly unreliable,and don't work for currents < 1.5A. Sparkfun has a good name, and this being low-current,I hope to have better luck. Will update report after testing.
