After reading the datasheet for the ACS711EX chip, I am left with the impression that varying ambient temperature may affect the readings of current flow. Where I want to use the current sensor would have an ambient range of -5c to +37c. That is based on uncontrolled outside temperature in north Florida. For other locations it would be different. The current sensor will not be exposed to rain/snow, but will operate in ambient temp/humidity.
Do I need an ambient temperature sensor to adjust the data being read to get consistent numbers ?
As far as I can tell, Pololu offers one temperature sensor, the MLX90614, but that is intended for measuring temperature of an object (and may be overkill for my needs). Would a thermistor be more appropriate ?
I know that the 32u4 has a temperature sensor onboard, but that is for chip temp, and may not correlate well to ambient.
TIA
