SCP1000 DEMO KIT
User Manual
The pressure (
Pres
) and temperature (
Temp
) is sent to PC in [Pa] and in 10
×
[°C] format. Example of
SCP1000 USB demo output data in high resolution mode below:
%102778 256$
→
pressure = 102778 Pa
temperature = 25.6 °C
%102779 257$
→
pressure = 102779 Pa
temperature = 25.7 °C
%102776 256$
→
pressure = 102776 Pa
temperature = 25.6 °C
