This project builds on the success of it's
predecessor, TEMP05. TEMP08 retains many of the previous features of the
TEMP05, and adds some extras.
Features of the TEMP08 include;
-
Standard RS232 serial interface between the
Dallas/Maxim 1-Wire bus and a host PC
-
Provides real-time relief for the host PC
by removing the burden of providing the precision timing required by the 1-Wire bus
-
Support for the following 1-Wire
environmental sensors;
-
DS18S20, DS18S20-PAR, DS1822, DS18B20 and DS1920
temperature sensors
-
DS2438 based Humidity Sensors
-
DS2423 based Lightning counters and
General Purpose counters such as Hobby Boards Dual
Counter
-
DS2423 based Rain Gauges
-
DS2450 Voltage Sensors
-
AAG 1-Weather Station (OWWS)
for wind speed, wind direction and outdoor temperature
-
Bray/Jennings DS2438 based Barometer
-
Dallas/Maxim iButtons (for security
applications)
-
Midon 1-Wire 4 Relay Output (1WIO)
or Hobby Boards 8
Relay Output
-
Midon 1-Wire Humidity Sensor
MD3020E and Hobby Boards 1-Wire
Humidity Sensor
-
Midon 1-Wire LED Displays (1WIO)
-
Easy option programming (Set and Forget)
- NO option jumpers required.
-
Capability to interface up to 60 different sensors
-
On-board DS2438 temperature sensor (Not available with MD2104S version)
-
Easily integrates into HomeSeer
software - see this page.
-
Supported by thermd
Thermometer Daemon freeware for Windows, Linux, Unix and Mac, which provides graphing and other capabilities.
For a 1-Wire interface to input/output
sensors, DS2405, DS2406 or DS2407, please see our companion 1WSwitch
product.

used instead of J1, 12 volt will not be available on J3.
-
J3 1-Wire and external interface.
Analog In, +12V, +5V, GND and
DQ provided.
-
J4 Serial Interface connector.
Standard DB-9 female connection.
-
J5 RJ-12 interface for 1-Wire
bus. +12V, +5V, GND and DQ provided.
