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

    • 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 Relays (1WIO and MD3020G)

    • Midon 1-Wire Humidity Sensor MD3020E

    • Midon 1-Wire LED Displays (1WIO)

  • Easy option programming (Set and Forget) - NO option jumpers required.

  • Capability to interface up to 60 different sensors

  • Built in 1-Wire interface to Midon 4 Relay Interface (1WIO)

  • On-board DS2438 temperature sensor

  • 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.

New Features

  • Optional on-board humidity sensor

  • Two on-board analog voltage inputs

  • Connectivity to 1-Wire bus via either terminal strip or RJ-12 connector

  • Discrete commands for setting all parameters

  • Real Time Clock for displaying time of day with results of sensor polls

  • PCB Size fits into optional PacTec CM5-125 case

  • EASY software upgrades via recyclable processor changes
