TEMPERATURE READING ON NG35

The NG35 is equipped with a TEMPERATURE SENSOR which can be useful to monitor the internal temperature. The

sensor is connected to the Nr. 9 internal ANALOG CHANNEL and it can be read with the system function ng_adc as for

the other analog inputs. To convert the value in degrees Celsius we have to do a calculation (see example).

Example

Function Read_Temp() as Long

Dim Degrees as Long

Degrees=NG_ADC(8) ' Read the temperature sensor

Degree= Degrees*3300/1024-600 ' Convert the value in 0.1 degrees

Read_Temp= Degrees

EndFunction
