EC Sensor V2 Returns 'nan' Possible Broken Library
joebentson 2018-09-10 09:04:25 2619 Views2 Replies Hello,
I just recieved the EC V2 SKU:DFR0300 and going straight from the WIKI (sample code and library) the sensor returns "EC:nan ms/cm" in the serial monitor. By testing the output voltage of the sensor and then using the V1 sample code and library I have confirmed that it is returning voltages, but the new code is not processing it correctly.
I think the new EC library might be broken, can anyone confirm this?

#include <EEPROM.h>
#define KVALUEADDR 0x0A
void setup(){
for(byte i = 0;i< 8; i++ ){
EEPROM.write(KVALUEADDR+i, 0xFF);
}
}
void loop(){
