1-Wire Outdoor Sensor/Interface Kit

Refer to the layout diagram for clarification of parts placement. All references to up, down, left, and right assume that you are looking at the PCB with the silkscreen TAPR logo on the right-hand side of the board. All components are mounted on the top of the PC board. If possible, use a piece of anti-static foam to lay the board and components on during assembly.

If you are not using the Davis Passive Radiation Shield, now is a good time to use the PC board as a template for marking the mounting holes in your enclosure.

The board is positioned as shown in the component layout with the TAPR logo positioned at the top. Note that the image as it appears in the browser is oriented with the board rotated 90°. This was done to facilitate printing. You will find it easier and far more convenient if you print the layout and place it with the logo oriented at the top while assembling the kit. All parts are installed on the top side of the board.

Check your soldering iron to be sure the tip is in good condition. The tip should be the small screwdriver tip type and must be clean. If you can't remember when you last replaced the tip, now would be a good time to do so. Surface mount devices are easy to solder if the tip is in good condition. If it isn't, be assured it won't be.

It is recommended that some type of conformance coating (environmental protection for the board and components) be applied before the installation. Any type of commercial grade conformance coating that is suitable for the components used will be OK. Be certain that whatever you use does not damage the Honeywell humidity sensor (check the honeywell site for more information).

A cheap and effective substitute is a hot glue gun. Some hints on how to apply a conformance coating using hot glue is covered in the final assembly page.
