11.1.12 +MMAD, Query and Monitor ADC Value
This command intends to query and monitor ADC value. G600 supports 2-ways ADC conerter.
This command returns the current ADC values for the requested channel. The values received
from the first converters represent the DC voltage levels of the input pin.
The returned value is a multiplication of the input level by 1000 (e.g. input level of 1 .56V will
return 156).

11.1.13 +MTSM, Temperature Sensor Measurement
This command measures the current temperature sensor value in Celsius degrees.
This temperature is taken from a Thermistor internally in Egold.
All the parameters are saved on the NVM, and used after power up.
All the parameter values should be 0 (zero) in first operation of the module.
