Customer:
Where can I find the register addresses for the MQ-9 Gas Sensor for use with I2C communication?
Pozdrav, Imam vaš MQ9 senzor te me zanima gdje mogu pronaći adrese registara tog senzora za upotrebu sa I2C komunikacijom.
Hvala unaprijed

If you have the easyC version, here is the code that runs on the ATTiny microcontroller that communicates via I2C: Soldered-MQ-Gas-Sensor-Arduino-Library/extras/attiny_firmware/attiny_firmware.ino at dev · SolderedElectronics/Soldered-MQ-Gas-Sensor-Arduino-Library · GitHub
The sensor itself only performs AnalogRead. The library handles other functionality through software. The other version of this sensor without easyC measures a digital pin (gas present/absent) and does analog read the same way as the I2C version.
ako imaš easyC verziju, ovo je kod koji se izvršava na AtTiny mikroupravljaču s kojim se komunicira putem I2C-a: Soldered-MQ-Gas-Sensor-Arduino-Library/extras/attiny_firmware/attiny_firmware.ino at dev · SolderedElectronics/Soldered-MQ-Gas-Sensor-Arduino-Library · GitHub
Dakle, senzor samo radi AnalogRead. Ostale stvari radi softverski library. Druga verzija ovog senzora koja nije easyC mjeri digitalni pin (plina ima/nema) i analog read isto kao I2C verzija.
Nadam se da ovo odgovara na tvoj upit.
Customer:
Do you have a detailed datasheet for the MQ-9 Gas Sensor with EasyC? The one I found on your pages is not very useful.
Imate li neki detaljan datasheet od Vašeg MQ9 senzora sa EasyC?
Onaj koji pronalazim na vašim stranicama nije mi baš od koristi.
Soldered Support:
That is the datasheet from the manufacturer, and I do not believe a more detailed datasheet exists for that model. If it helps, here is the readme from the library that we use internally: Soldered-MQ-Gas-Sensor-Arduino-Library/src/libs/MQUnifiedsensor at dev · SolderedElectronics/Soldered-MQ-Gas-Sensor-Arduino-Library · GitHub
to je datasheet od proizvođača te ne vjerujem da za taj model postoji detaljniji datasheet kao takav. Ako pomaže, evo readme iz library-a koji mi interno koristimo u našem: Soldered-MQ-Gas-Sensor-Arduino-Library/src/libs/MQUnifiedsensor at dev · SolderedElectronics/Soldered-MQ-Gas-Sensor-Arduino-Library · GitHub
Nadam se da to pomaže s razvojem
