I’m looking at a water pressure sensor that is 0.25% accurate across it’s range of 0-100 psig.
The output options for ordering the sensor are:
*Power Requirements: 10-30 VDC (for4-20 mA, 0-5, 1-5, 1-6 VDC outpus);* *13-30 VDC (for 0-10, 2-10 VDC outputs);* *5 VDC ±0.5 VDC (for 0.5-4.5 VDC ratio-metric output).* *Current Consumption: 38 mA maximum (for 4-20 mA output);* *10 mA maximum (for 0-5, 1-5, 1-6, 0-10, 2-10, 0.5-4.5 VDC output);*
Since the Electron’s analog input pins are 3V3, what Pressure Sensor Output Option should I choose to not sacrifice precision when implementing with an Electron?
The simplest to me is powering the sensor’s 10 mA load directly from the Electron & the 0.5 - 4.5V Ratiometric Output with the Electron sampling a voltage divider,
All ideas and comments are welcomed. Thanks in advance for your help!
