I'm trying to use a ACS756SCA-100B - 100A Hall Effect-Based Linear Current Sensor IC (SCT-013-030) with a precision of 20 mV/A.
My objective is to read input voltage coming from the sensor into the XBee Analog input.
I was wondering if that would be possible by making precision half-wave rectifier, to rectify the sensor output into the XBee. I know that even with half-wave I still get a variation, so I guess that's far from perfect...
On the other hand I've seen these type of projects working with arduino, but as far as I understood, it will basically sample the AC wave a number of times and applies the RMS on it afterwards.
Is it possible to use XBee directly or must I process the wave first on a microcontroller?
