The temperature is read every second unless a longer EDS007X/delay is given. Data is presented in the specified temperature scale, Celsius by default.

Ambient pressure, measured every 0.2 seconds. Data in the selected pressure scale (default mBar).

read-only, floating-point

read_only, unsigned integer
Vibration registered by sensor (instantaneous value) in 0-1023 range.

read_only, unsigned integer
Vibration registered by sensor (highest recent value -- slowly decays) in 0-1023 range.

read_only, unsigned integer
Vibration registered by sensor (lowest value) in 0-1023 range.

read_only, unsigned integer
Vibration registered by sensor (highest value) in 0-1023 range.

The EDS0080 and 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.

read-only, floating point
Current current level. (4-20mA)

read-only, floating point
Maximum and minimum current readings since last alarm/clear command.

The EDS0082 and 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.

read-only, floating point
Current voltage level. (0-10V)

read-only, floating point
Maximum and minimum voltage readings since last alarm/clear command.

High and low range of acceptable sensor readings. Values outside this range will trigger an alarm if the corresponding EDS00XX/set_alarm flag is set.

read-write, floating-point
Threshold temperatures in the specified temperature scale. Default Celsius.

read-write, floating-point
Threshold humidity values. Dew point and Heat index are in the specified temperature scale. Default Celsius.

read-write, floating-point
Threshold barometric pressure values. Pressure is the specified pressure scale. Default mBar.

read-write, unsigned
Threshold light (lux) values.

read-write, unsigned
Vibration sensor alarm limits in 0-1023 range.

read-write, floating-point
Threshold RTD resistance values (Ohm).

read-write, floating-point
Voltage or current threshold limits

Set conditional alarm to trigger if corresponding flag is set. Also must set high and low threshold.

read-write, yes-no
Flag to set corresponding out-of-range alarm. "1" turns on flag, and "0" turns off.

Show or clear the out-of-range flags. When set, the device will respond to a conditional search. Clearing the flags is performed with the EDS00XX/alarm/clear command, not just having the measured value return to the center range.

write-only, yes-no
Write "1" to clear ALL the alarm flags.

read-only, yes-no
Show corresponding out-of-range alarm. "1" means in alarm state. Can only be turned off with clear

Optionally found on the EDS006X and EDS007X. Can be controlled by software or the alarm condition.

read-write, unsigned
Set the relay control scheme:

0
alarm control with hysteresis
1
alarm control but need EDS00XX/alarm/clear to unset
2
Control with EDS00XX/relay/state
3
Always off

read-write, yes-no
Turn the relay on or off if the EDS00XX/relay/control is set to 2

Found on the EDS006X and EDS007X. Can be controlled by software or the alarm condition.

read-write, unsigned
Set the LED control scheme:

0
alarm control with hysteresis
1
alarm control but need EDS00XX/alarm/clear to unset
2
Control with EDS00XX/LED/state
3
Always off

read-write, yes-no
Turn the LED on or off if the EDS00XX/LED/control is set to 2

read-only, unsigned integer
Approximate seconds since power up.

read-only, unsigned integer

read-write, yes-no
Clear the pulse count on the corresponding channel.

read-only, unsigned integer
Approximate samples since power up.

read-write, binary
96 bytes of memory. Not all is writable. Access to EDS00XX functions is better accomplished through the data fields, which expose all the chip features.

read-write, binary
Memory is split into 3 pages of 32 bytes each. Only page 2 is writable. ALL is an aggregate of the pages. Each page is accessed sequentially.

read-write, binary
160 bytes of memory. Not all is writable. Access to EDS008X functions is better accomplished through the data fields, which expose all the chip features. The EDS008X has more memory than the other chips, so a separate entry in the sudbirectory makes it available.

read-write, binary
Memory is split into 5 pages of 32 bytes each. Only page 5 is writable. The EDS008X has more memory than the other chips, so a separate entry in the sudbirectory makes the extra pages available. ALL is an aggregate of the pages. Each page is accessed sequentially.

read-only, ascii
Text description of the device. Up to 30 characters.

read-only, ascii
Device name. E.g: "EDS0071"

read-only, unsigned
Number corresponding to the hexadecimal type. E.g:
EDS0071 -> 0x0071 -> 113 in decimal

The EDS00XX sensors are a family of devices from Embedded Data Systems. Although provisional support for several types is included, only early EDS0071 has been tested with OWFS.

The sensors all share the same 7E family code. They have the same first memory page layout with a text tag property that describes them, and a sub-type field giving the particular sensor. The data properties shown in a directory listing will be specific to the sensor sub-type.

The 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.

The EDS00XX sensors are read and controlled by accessing parts of their on-chip memory. Although the raw memory contents are exposed in the memory and pages fields, all the available functionality is best accessed by the other fields. In fact, directly changing memory will confuse OWFS.

All the EDS00XX sensors have an LED and optional relay. Both can be controlled either directly, or when the sensors reaches an alarm state.

See the file man3/addressing.3so.
