Pressure, Temperature, and Humidity Sensors
Checking the Settings (aTU)
With this command you can check the current pressure, temperature and
humidity sensor settings.
Command format in ASCII and NMEA 0183: aTU
Command format in SDI-12: aXTU!
The response in ASCII and NMEA 0183:
aTU,R=[R],I=[I],P=[P],H=[H]
The response in SDI-12:
aXTU,R=[R],I=[I],P=[P],H=[H]
where [R][I][P][H] are the setting fields, see the following section.
Example (ASCII and NMEA 0183, device address 0):
0TU
0TU,R=11010000&11010000,I=60,P=H,T=C
Example (SDI-12, device address 0):
0XTU!0XTU,R=11010000&11010000,I=60,P=H,T=C
