To read the Switch state, must use the polling method. (interrupt feature is not implemented)

ADC
/sys/devices/platform/ioboard-adc/
enable : on/off (read/write)
value : ADC raw value (0~4095)
voltage : 0V ~ 1800mV 

Ambient Light Sensor (Software driven bit-bang I2C)
/sys/devices/platform/i2c-gpio.10/i2c-10/10-0029
enable : on/off (read/write)
lux : sensor value in Luix (0 ~ 65535 lux)

Pressure Sensor/Temperature Sensor (Software driven bit-bang I2C)
/sys/devices/platform/i2c-gpio.10/i2c-10/10-0077
enable : on/off (read/write)
pressure : atomospheric pressure, pa unit. (ex)101614(pa) = 1016.14hpa
temperature : 10 times.... (ex) 195 = 19.5C
