I2C_SDA : GPIO2
I2C_SCL: MTMS
These two I2C lines should be pulled up inside or outside the chip.
Some sensor drivers can be found in SDK/app/driver.
Include :
BH1750 light sensor , I2C
MP085 pressure sensor,i2c
MVH3004 temperature and humidity sensor.
An analog voltage output of a CH4 gas sensor is connect to the tout pin , scaled to 1v from 5v via split-voltage resistance.
