USB to One Wire converter - Virtual Com Port FT232RL based
This adaptor connects your 1-Wire network to your computer. It appears as Virtual Com Port (VCP) and it is based on the FT232RL (USB-UART converter) and DS2480B Dallas-Maxim (RS232-One Wire converter). It has selectable RC filter for improving communication for lines between 1 and 100 meters and ESD line protection. It is compaitable with DS9097U of Maxim-Dallas with the difference this adaptor is connected to your USB port

* The device can not program 1-wire EPROM devices
** The network weight is the length + devices weight. For example iButtons devices have weight 1m and non-iButtons have 0.5m. If the length is 100m and there are 200 sensors DS18S20 connected then the total weight is 200m. In our laboratory, the converter is tested with 300 meters twisted pair cable with 20 DS18S20 sensors and worked stable.
The package contains
- 1 x USB to One Wire interface module converter
- 1 x Temperature sensor DS18S20+
Typical applications
- Home Automation
- Industrial Automation
- USB thermometer/logger (with combination of temperature sensor and software)
- USB - One Wire bridge
- Distributed systems for measurement temperature, voltage and so on...
Connecting the convertor with DS18S20
Together with DS18S20, the USB One Ore converter can be easily turned into USB Thermometer/Logger (of course with PC software). Bellow it is shown how to connect one such sensor (additional sensors can be bought separately from us). In this way you can measure temperatures from -55°C to +125°C (-67°F to +257°F).
How to connect single DS18S20 sensor to the converter. It takes seconds!
OneWireViewer
There are many One Wire based sofware solutions on the market. One such software (free offered by Maxim-Dallas) is OneWireViewer. With this software the adaptor can be easily tested. The software will be available on your PC after you install the One Wire drivers (it will apprear as executable program).
Lanmisoft Home Automation Software
Another very popular Windows software is Home Automation Software by Lanmisoft. Bellow it is given screenshot maden at a time when this software and Denkovi USB One Wire converter work with 300 meters twisted pair cable and dozen of DS18S20 and DS18B20 sensors. The software is very flexible and can work also with our USB 4 Relay Board and USB 8 Relay Board. The software is tested by us and it is warmly recommend for Home Automation applications. Please note there is free demo on the developer's web page so you can test it or you can purchase the full version.
Denkovi USB to One Wire converter is very important part of the home automation system presented on the image bellow. The PC with Lanmisoft Home Automation software handles the one wire network with temperature sensors (for example DS18S20) and several denkovi relay boards (USB 4 Relay board and USB 8 Relay board). Basicly the system can control relays based on temperature level, timers and pulses. Please note that all the components of such Home Automation system can be found on our web site. The Denkovi USB to One Wire converter (and Denkovi USB 4/8 Relay Boards) are tested with this software and we can confirm they work stable (for converters and USB Relay Boards from other suppliers we don't guarantee).

DS18B20 Temperature Sensor waterproof 1M, range: - 55 C to +125 C
A waterproofed version of DS18B20 digital thermometer which provides 9-12 bits Celsius temperature measurements. The DS18B20 communicates over a 1 - Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor. Usable with 3.0-5.5V systems. The cable is jacketed in PVC so we suggest keeping it under 100 degree C.
