Re: Sensors return 0 value

So, if I understood, I bought a calibrated sensor but now I need to calibrate it myself and I need a clean room free of NO2 and CO..etc.. ? I don't know what is the value os NO2, CO or CO2 to set my offset ... And if I make this: for (uint8_t i = 0; i < 10; i++) { concentration = concentration + se...

Re: Sensors return 0 value

Hi,

But if I set the zero point I ignore the calibrated value.. this is not a solution...

check the problem here:

I think that the only correct value is 515 .. 0 is not correct... the sensors are side by side (500m - public area / green area ) .

Thanks.

Re: Sensors return 0 value

Hi, The problem is that value result is a negative value and your code convert negative values to zero. RANDOM CORRECT VALUE: EXAMPLE FOR 03 SENSOR - 9374-P (SOCKET F) and BME (SOCKET E) H# Electrochemical gas sensor example A BME sensor in socket A is also required [GASES PRO] OFF function [GASES P...

Re: Sensors return 0 value

Hi, Thanks for your reply, by default I use always 2 minutes in deep sleep. I have more than 10 sensors and if I put side by side with same firmware the result it's not the same. https://i.ibb.co/fST5jWh/sv.png Maybe this"zeroPointSet" solve my problem and put the sensors in the same conditions.

Re: Sensors return 0 value

If I use this:
concentration = gas_sensor.getConc(MCP3421_ULTRA_HIGH_RES);
I get an error:
call of overloaded 'getConc(int)' is ambiguous


gas_sensor.configureAFE(LMP91000_GAIN_1); or gas_sensor.configureAFE(LMP91000_GAIN_7); return the same value.

Hi, I don't understand 0.000000 concentration value. Usually NO2 and 03 (sometimes in CO2) return 0.00000 as concentration. Is there any explanation ? wake up!!

Re: sd card does not respond

No.
Not Work.
No sensors and all native sd card examples.
