ac analogue input
« on: June 04, 2019, 04:03:34 am »
hi, i want to make a project to analyse the ac power consumption and have 2 pickup coils for generation and consumption.
is digispark powerful enough to take these two 0-300mv 50hz signals and software rectify them into variables (ultimately a single variable denoting difference) to work with another section of code, or if cpu power is all used, another digispark.
the idea is to directly read the coils because a digispark, even 2 or 3 are still cheaper than a set of instrumentation amplifier or precision rectifier circuit.
