NAME
HobbyBoards EE/EF - Microprocessor-based slaves
UVI - Ultra Violet (UV) Index sensor

SYNOPSIS
General EE device
EE [.]XXXXXXXXXXXX[XX][/[ temperature | version | type_number | temperature_offset | ]]

UVI sensor
EE [.]XXXXXXXXXXXX[XX][/[ UVI/UVI | UVI/UVI_offset | UVI/in_case | UVI/valid | temperature | version | type_number | temperature_offset ]]

General EF device
EF [.]XXXXXXXXXXXX[XX][/[ version | type_number | ]]

FAMILY CODE

EE  Device with temperature

EE  UVI

EF  Device without temperature

TEMPERATURE PROPERTIES

  temperature
read-only, floating point
Temperature read every 30 seconds. Resolution .5C (uses an on-board DS18B20). Temperature is only present in the EE-series devices.

  temperature_offset
read-write, floating point
Offset stored on device to apply to temperature readings.

UVI PROPERTIES

  UVI/UVI
read-only floating point
UV Index (ultraviolet index) in the range 0.0 to 16.0 resolution .1

Only the UVI version of the EE device has a UVI sensor. Readings made every .5 seconds.

  UVI/UVI_offset
read-write, floating point
Signed offset to apply to the UVI measurement. Stored on-device non-volatile.

  UVI/in_case
read-write, yes-no
Flag to apply compensation for the protective case. Stored on-device non-volatile.

  UVI/valid
read-only, yes-no Flag the the EE device type matches the known UVI type.

IDENTIFICATION PROPERTIES

  version
read-only, ascii
Firmware version for the EE/EF device. Reported in HH.HH format where HH is a hex digit (0-9A-F).

  type_number
read-only, integer
Index of the type of sensor built into this device. Current known assignments:

1   UVI

STANDARD PROPERTIES

ALARMS
None

DESCRIPTION

  EE / EF
The EEEF (3) are a reference platform of microprocessor based 1-wire slaves. In general they require external power, and have an on-board index for the specific capabilities. They are designed by Eric Vickery at HobbyBoards.com

The EE class device uses family code EE and has an included temperature sensor. The EF devices have no temperature sensor,

  UVI
The UVI sensor is an implementation of the EE class device with Ultra Violet Index sensing. All it's specific properties are in the UVI/ directory.
