ACS712 and ZMPT101B

Other Hardware Sensors
1

Hi all,

I'm trying to perform power consumption by using the ACS712-5A current sensor with ZMPT101B AC voltage sensor. However, when the load appliances is connected, there's no respond to either one of the sensor. I've tried the sensor one by one using ESP32 and Arduino. My first step is to read the analog output which I believe it will change when there's voltage/current flowing through the sensor. But, the sensor remain around 1800 (ESP32). So, I'm trying to look for any solution if there's anything I'm doing it wrong. I believe the connection shouldn't be a problem since it's directly connected to the terminal of the sensor and the coding is the simple coding to read analog output of the sensor.

Since you are measuring an AC current the output will be AC. Also the value of the shunt will need to be considered. Post an annotated schematic showing exactly how you have wired it especially power, ground and power sources. Links to the actual parts that give technical information would also help.
