A source plugin for the TEMPerHUM, a simple USB hygrometer made in China. TEMPerHUM is used to monitor brewing gear, server rooms, etc. You can pick it up on eBay for about $20 (used to be $15). This plugin can monitor multiple devices. It's similar to the regular TEMPer, except it adds humidity and dew point data.
This plugin is for the newer TEMPerHUMs with HID interface, made after mid-2009. Older TEMPerHUMs used a virtual COM port. The makers of TEMPer often change the interface, which makes plugin development hard.
The TEMPerHUM plugin has just one function, GetData, with these parameters:
|display string||Info to be shown, formatted with tags listed below. For graphs or progress bars, use one tag with no symbols.|
|device ID||Which TEMPerHUM to monitor. The index starts at 0.|
|decimal places||The number of decimal places to show.|
|temp. calibration||Add this much to the reported temperature value.|
|hum. calibration||Add this much to the reported humidity value.|
Use these tags in the display string:
|[tempF]||temperature in Fahrenheit|
|[tempC]||temperature in Celsius|
|[dew]||dew point: the temperature to which air would have to be cooled down for vapor to condense into water|
|[devcnt]||number of attached devices|
The calibration values for my TEMPerHUM are: -1.5°F for temperature and +2.65% for humidity compared to the Digi Watchport sensor.
