.SH TEMPERATURE
.SS EDS006X/temperature
.I read-only, floating-point
.br
Temperature for the EDS006X series of chips. In the \-55C to 125C range, with 0.0636C precision. The temperature is read every second, continually. Data is presented in the specified temperature scale, Celsius by default.
.SS EDS007X/temperature
.I read-only, floating-point
.br
Temperature for the EDS007X series of chips. Read using a wide-range precise RTD sensor. Typical range is \-60C to 260C with 0.15C accuracy, although a range of \-200C to 850C is possible. The temperature is read every second unless a longer
.I EDS007X/delay
is given. Data is presented in the specified temperature scale, Celsius by default.
.SS EDS007X/resistance
.I read-only, floating-point
.br
Actual measured resistance (Ohms) of the RTD element. Useful if the RTD element doesn't conform to the typical European IEC 60751 standard.
.SH HUMIDITY
.SS EDS006X/humidity
.I read-only, floating-point
.br
Relative humidity in the 0-100 range (percent). Read every 0.2 seconds.
.SS EDS006X/dew_point
.I read-only, floating-point
.br
Dew point computed from
.I EDS006X/temperature
and
.I EDS006X/humidity
computered every 0.2 seconds. Data is a calculated temperature and is reported in the specified temperature scale. Default Celsius.
.SS EDS006X/heat_index
.I read-only, floating-point
.br
Heat index computed from
.I EDS006X/temperature
and
.I EDS006X/humidity
computered every 0.2 seconds. Data is a calculated temperature and is reported in the specified temperature scale. Default Celsius.
.SS EDS006X/humidex
.I read-only, floating-point
.br
Humidex (popular in Canada) computed from
.I EDS006X/temperature
and
.I EDS006X/humidity
computed every 0.2 seconds. Data is a percent and reported in the 0-100 range.
.SH LIGHT
.SS EDS006X/light
.I read-only, unsigned integer
.br
Ambient light in Lux. Measured every 0.2 seconds.
.SH PRESSURE
.SS EDS006X/pressure
.I read-only, floating-point
.br
Ambient pressure, measured every 0.2 seconds. Data in the selected pressure scale (default mBar).
.SS EDS006X/inHg
.I read-only, floating-point
.br
Ambient pressure, measured every 0.2 seconds. Data in the inHg scale.
.SH VIBRATION
.SS EDS0070/vib_level
.I read_only, unsigned integer
.br
Vibration registered by sensor (instantaneous value) in 0-1023 range.
.SS EDS0070/vib_peak
.I read_only, unsigned integer
.br
Vibration registered by sensor (highest recent value -- slowly decays) in 0-1023 range.
.SS EDS0070/vib_min
.I read_only, unsigned integer
.br
Vibration registered by sensor (lowest value) in 0-1023 range.
.SS EDS0070/vib_max
.I read_only, unsigned integer
.br
Vibration registered by sensor (highest value) in 0-1023 range.
.SH CURRENT
The 
.B EDS0080
and
.B EDS0083
measure current in the 4-20mA range, with upper and threshold limits and the ability to set an alarm and independently trigger a relay if the value is out of range.
.SS EDS0080/current.[0-7|ALL] EDS0083/current.[0-3|ALL]
.I read-only, floating point
.br
Current current level. (4-20mA)
.SS EDS0080/max_current.[0-7|ALL] EDS0080/max_current.[0-3|ALL]
.SS EDS0083/min_current.[0-7|ALL] EDS0083/min_current.[0-3|ALL]
.I read-only, floating point
.br
Maximum and minimum current readings since last
.I alarm/clear
command.
.SH VOLTAGE
The 
.B EDS0082
and
.B EDS0085
measure voltage in the 0-10V range, with upper and threshold limits and the ability to set an alarm and independently trigger a relay if the value is out of range.
.SS EDS0082/volts.[0-7|ALL] EDS0085/volts.[0-3|ALL]
.I read-only, floating point
.br
Current voltage level. (0-10V)
.SS EDS0082/max_volts.[0-7|ALL] EDS0085/max_volts.[0-3|ALL]
.SS EDS0082/min_volts.[0-7|ALL] EDS0085/min_volts.[0-3|ALL]
.I read-only, floating point
.br
Maximum and minimum voltage readings since last
.I alarm/clear
command.
.SH THRESHOLD
High and low range of acceptable sensor readings. Values outside this range will trigger an alarm if the corresponding
.I EDS00XX/set_alarm flag is set.
.SS EDS00XX/threshold/temp_hi EDS00XX/threshold/temp_low
.I read-write, floating-point
.br
Threshold temperatures in the specified temperature scale. Default Celsius.

.SS EDS00XX Overview
The EDS00XX sensors are a family of devices from 
.I Embedded Data Systems.
Although provisional support for several types is included, only early
.I EDS0071
has been tested with
.I OWFS.
.PP
The sensors all share the same 
.I 7E
family code. They have the same first memory page layout with a text
.I tag
property that describes them, and a
.I sub-type
field giving the particular sensor. The data properties shown in a directory listing will be specific to the sensor
.I sub-type.
.SS EDS0071
The
.B EDS0071 (3)
is a micro-processor based 1-wire slave made by EDS (Embedded Data Systams). Is uses a high accuracy and extended range RTD sensor to accurately measure temperatures.
.SS Memory
The
.I EDS00XX
sensors are read and controlled by accessing parts of their on-chip memory. Although the raw memory contents are exposed in the 
.I memory
and
.I pages
fields, all the available functionality is best accessed by the other fields. In fact, directly changing memory will confuse
.I OWFS.
.SS Relay and LED
All the
.I EDS00XX
sensors have an LED and optional relay. Both can be controlled either directly, or when the sensors reaches an alarm state.
