1-Wire Humidity Module

             The perfect companion for the TAI8515 Weather Instrument, the TAI8540D 1-Wire® Humidity Module can be installed on any existing 1-Wire® network. Based on the HIH-4000 humidity sensor, manufactured by Honeywell, and using the DS2438 IC from Dallas Semiconductors as a 1-Wire  front end and a A/D converter, the  TAI8540D not only permits to measure the relative humidity, but also the temperature.

            The unit obtains the power it needs directly from the 1-Wire® network, without any need for an external power supply.          

         As with all 1-Wire® devices, it comes with a unique 64 bit address,  so multiple units can be distinguished on complex networks.

              The TAI8570 1-Wire pressure sensor allow you to measure the atmospheric pressure. The perfect companion for the TAI8515 Weather Instrument, the 1-Wire® Pressure Sensor can be installed on any existing 1-Wire® network. The unit obtains de power needed to operate directly from the 1-Wire® network, without need of an external power supply.

              Provided with an unique 64 bit address each unit can be identified on complex networks And several sensors can be installed on the same network for diferential pressure monitoring

                The DS9490R is a USB bridge with 1-Wire RJ11 interface to accommodate 1-Wire receptacles and networks. The DS1402D-DR8 (Blue Dot™) can readily be used in conjunction with the DS9490R to create an iButton PC reader.

                The DS9490 can be used with the 1-Wire Weather Instrument and with any of the 1-Wire modules offered by AAG Alectronica LLC.

                The adapters is based on the DS2490 USB to 1-Wire bridge chip. PC software drivers for Windows ® 98, Windows 2000, Windows ME, and Windows XP can be found on the iButton website
