WCS1800 Hall effect Current sensor and ESP32

[regan.x]

Hi ESP forum,

I'm facing difficulty in configuring Winson's WCS1800 Hall effect current sensor with ESP32 to measure the AC current. I got to know that, +5V has to be supplied to the Hall effect current sensor. Do we need to add a voltage divider circuit to convert the Aout value to 3.3V before sending to ESP32?

Kindly clarify.

Datasheet of that device specifies the supply voltage can be anywhere within 3 to 12V, so I'd simply feed it off the 3.3V rails. If you still want to feed it off 5V, you'd indeed need a resistive divider.
