Change Range for SEN0244 TDS Sensor Meter?
AJGraham 2022-10-14 02:41:09 1631 Views1 Replies Hey, is there any way to change the calibration of the sensor to read from 500PPM to 1500PPM?
I understand out of the box it's supposed to be from 0-1000 but for hydroponic applications 500-1500 is much more useful. I'm not looking to expand the range but shift the calculation. I have a separate PPM meter I can use to help me with my calibration, but I just want to know where/what I should change to affect this.

Hi
Gravity: Analog TDS Sensor/ Meter for Arduino(SKU: SEN0244) is a pure analog sensor, with voltage output 0V to 2.3V from 0 to 1000PPM. Which means that the measurement range is fixed by hardware.
I'm sorry that you can not measure 1500PPM because the operational amplifiers on board can not output that voltage.
