Re: Multichannel gas sensor

Hi, I'm abandoning this way and will continue with an Arduino-board. The solution you posted works in about 50% of the tests so it's not reliable (at least it did so in my tests). So it looks like it's a problem with the software. Using an Arduino-board I did not encounter any problems with this sen...

And you do the endTransmission() twice. So I changed it and here is my code: unsigned int MutichannelGasSensor::get_addr_dta(unsign...

Hi, I have a seeeduino LoraWan with GPS and I added the Multichannel gas sensor to it using one of the outer Grove-connectors on the board. From the Arduino-forum I got a program that scans the I2C-bus and reports. Here is the result: Scanning... I2C device found at address 0x04 ! done This looks go...
