MBox Meteostation
Features
MBox is a small, self-contained weather sensing device that delivers barometric pressure, temperature, humidity and dew point information with high accuracy. It features a Micro-USB port and comes in a handy, small enclosure.
The driver supports reading the following sensor data:
- Temperature (C): Inside temperature in Celcuis.
- Humidity (C): Relative Humidity %
- Barometer (millibars): Barometer pressure value.
- Dew Point: Dew point in Celcius.
All parameter values have an Ok, Warning, and Alert ranges that can be specified by the user in the Parameters tab. Temperature is considered a Critical Paramter. Critical paramters are listed in the main control tab in the Weather status property. The user can specify the minimum and maximum range for each zone. Any value outside the Warning zone is automatically considered Alert. The overall weather status property reflects the worse state of the individual critical parameters. If one critical paramter status is Warning while another is Alert then the overall weather status property is Alert. The weather status property may be used for decision making by clients application. For example, when the weather status is Alert, the client application may commence a precautionary shutdown of the observatory to protect its equipment from adverse weather conditions.
Operation
Before you connect, check that the port and baud rate settings in the Options tab are correct. By default, the port is /dev/ttyUSB0 and the baud rate is 38400. You can specify the update period is seconds (default 60) in the main control panel. To update weather data manually, press the Refresh button. If you change the paramter ranges under the Paramters tab, save the ranges in the configuratio file by clicking on Save in the Options tab.
You can set Offsets for each sensor to adjust its reported value in the Main Control Panel.
