  • grove-linux-driver

    Grove linux driver for Grove-Base-Cape

  • Seems primary, and only communication is over the I2C bus, so you could write your own driver to interface with the sensor. I assume you are working with some lite version of Raspbian/Debian distribution, in which case it makes it easier to test and load the written module. I see here at: https://github.com/Seeed-Studio/grove-linux-driver there appears to be some generic support for some other Grove devices. This might be a good example/starting point for you - and because you don't appear to have a proper datasheet, you could potentially scan the source code at https://github.com/Seeed-Studio/Mutichannel_Gas_Sensor and figure out the required register addresses for communication and data transfer. Otherwise maybe there is a more detailed datasheet about register mapping somewhere on the web or you could contact the manufacturers.

  • Mutichannel_Gas_Sensor

    This Arduino library is used for driving "Xadow - Mutichannel Gas Sensor" and "Grove - Mutichanel Gas Sensor"
