The 1-Wire™ sensor kit was designed to be used with the TAPR T-238+ APRS Weather Station or N4XI's Linux based WXN weather server over APRS. The humidity and barometric pressure sensors, as well as the rain gauge interface should work with any other 1-Wire™ based software as the design is based on the original Dallas Semiconductor 1-Wire™ Weather station.
The board features the following:
Barometric Pressure Sensor: Motorola MPX4115AP
Temperature Sensor: Dallas Semiconductor DS18S20
Rain Gauge Interface or radiation monitor input.
EMP (lightning detector) interface.
Aspirator control for X1W-2.
Rain Gauge Heater Control.
Pads for installation of optional 1-Wire iButton Clip.
The X1W-1 kit does not come with an enclosure.
The price for the X1W-1 Bare PCB is:
$ 14 US for members of TAPR
$ 15 US for non-members+ shipping/handling if applicable.

ALSO There is a problem with Chrome inaccurately reporting that the connection is insecure when you are attempting to complete your order. We suggest using a different browser to place the order.
Both problems are being worked on, sorry for the inconvenience.
Shipping and Handling
Shipping and Handling within the US will be by USPS Priority Mail.
International shipping costs are calculated as closely as possible. If the actual cost exceeds the estimate by more than $10.00, TAPR will contact you to get approval for the additional funds. TAPR uses insured Priority Mail International, unless the purchaser requires something else.
Sorry, N4XI - X1W-1 BP Sensor is no longer available
Assembly and Operations ManualThe assembly and operations manual can be found online at http://www.tapr.org/n4xi-tmp-html/x1w-1/
SupportTAPR kits can be complex depending on the kitting experience of each builder. We don't think you will have trouble with the kit, but it does require some knowledge and experience to successfully go from a kit to a finished, usable unit, depending on the mode of operations.
The T-238 series and the X1W series of kits are discussed on the Weather Special Interest Group (WXSIG). You can join WXSIG via the web at:
