analog conductivity sensor

Hi, I'm trying to use a DFR0300 conductivity analog sensor + his driver, with a constant cell K=10, and I want to know if the driver of a K=1 cell is compatible with a K=10 cell, or if I can change the firmware library for work with one or another of them.

 

thanks sine now

I faced a similar issue when experimenting with sensor calibration and found that compatibility depends on how the driver handles signal scaling Adjusting the firmware can help much like fine tuning strategies in 99 Nights in the Forest where precision makes all the difference in achieving balance.

Great question! From my experience, the DFR0300 conductivity sensor driver is calibrated for specific cell constants, so using a K=1 driver with a K=10 cell may cause inaccurate readings. You might adjust the calibration functions or modify the firmware parameters. I ran into something similar while coding a real-time monitoring setup for my [uno online](https://unoonlinefree.com)  project—it helped me understand how calibration constants influence data precision.

Hi, I'm using an ESP32 and the driver is this: https://www.mouser.com/pdfDocs/Product_Overview-DFR0300-HGravitySeriesAnalogSensorMeter.pdf, https://github.com/DFRobot/DFRobot_EC10

Hello, which driver are you using? Any link? And what is your main processor? ARduino UNO or something else?
