This is the forth generation weather station I built. For this build a decision was made to look at a more professional anemometer and wind direction instruments rather than using ones that I previously built. After doing some searching I found the OurWeather - Complete Weather Kit sold by SwitchDoc Labs. It is a complete kit that met most of my needs. When it arrived I was able to put the components together and had it running in about 20 minutes. The kit comes with a mini display that displays the data.

Looking at all documentation I found two potential issues that redirected my plans. Using the weather board that came with the kit I was supposed to be able to access the data stream by IP address of the board. I wrote a program to extract the data but ran into a problem after a few cycles when the weather board kept locking up. Reading the SwitchDocs forum I found that it was a common problem. The second issue was losing the Humidity reading. After a few minutes the Humidity sensor was displaying a NAN return.

Since my main goal was to read the data through a VB6 app, display the data and store it in a database, I needed to take a different approach. I purchased a new Arduino 2560 v3 board, an Ethernet shield and prototype board. The 2560 board would to most of the heavy work. Looking at the SwitchDoc Labs web site I found two boards that would work with the anemometer and wind direction instruments.

I purchased WeatherPiArdinuo V3 w/Grove (aka Weather Board) connectors and Grove/Pin Headers I2C 4 Channel Mux Extender/Expander Board. These two boards could interface the anemometer and wind direction to the Ardiuno with the multiplexor allowing additional I2C connections.

Another decision was made to go with hard wired Ethernet connections rather than wireless. The data transfer from the Ardunio boards would be through UPD. The location of my notebook running the VB6 app in the previous wireless build was not very reliable a hard wired connection was a must.

The photo below shows the layout of the components. I used a 12Ē x 12Ē x 6Ē electrical box. I constructed a mounting plate out of 3/32Ē ply wood so I could remove it for easy maintenance. Since the Arduino has limited connections for 5 volt and ground I made a custom header to provide the sensors with a central location for power. The Ardunio stack consists of the 2560 v3 board, the Ethernet shield and a custom prototype shield. I added prewired headers for the sound, light and vibration sensors.

The temperature/barometric pressure/humidity sensor that came with the kit had issues so I replaced it with an new sensor. The sensor was connected to the 4 Channel Mux board along with the LCD display.

An LCD display was added to the main case to display the sensor data.

One issue that could have been a show stopper was the power source. For reasons that no one could explain the Arduino boards would not work with an external power supply. It would only work from the USB port connected to a computer. I have a 70 amp 12 volt power supply that even had issues powering the board. There was no reason for this since the power consumption for both systems was very low. I didnít want to have to run two USB lines from my notebook to each of the Ardunio boards from inside the house. I took a chance and ordered a AmazonBasics 3-Outlet Surge Protector with 2 USB Ports to see if that would be able to power the systems. It worked. To power the radar system, which has its Ardunio board on top of its mast, I purchased a 50 foot HDE USB Extension Cable. I wasnít sure if it would work but it did as well.




The Arduino code for the weather station was based on the SwitchDocs example code. I started out by stripping out the code that I didnít need. Code was added to support the new T/BP/H sensor, LCD Display, sound, light and vibration. The 4 Channel Mux library code was added to detect if there are I2C sensors present. I will post the code after I do a little more clean up work.

The data was converted to English units and statements were added to send the data via UDP across the network specific port and IP address. The code speccifies a a specific local and remote port for the data to be streamed.

Grove/Pin Headers I2C 4 Channel Mux Extender/Expander Board for Arduino and Raspberry Pi

The Grove I2C 4 Channel Mux Breakout Board is a TCA9545A based quad bidirectional I2C Expander and Multiplexor controlled via the I2C bus with GROVE connectors. The SCL/SDA controlling fans out to four downstream channels. It works for both the Arduino and Raspberry Pi. At SwitchDoc Labs, we love data. And we love I2C devices. We like to gather the data using lots of I2C devices on our computers and projects. We are always running into conflicts with addressing on the I2C device. Since there are no standards, sometimes multiple devices will have the same address, such as 0x70 and you are just out of luck in running both of them on the same I2C bus without a lot of jimmy rigging. You can have any combination of 3.3V and 5V I2C busses on this board. What is the solution for this? Itís an I2C controlled 4 I2C bus multiplexer! We have both Grove Connectors and traditional pin headers. Grove connectors make it easy to use with no soldering! SwitchDoc Labs is building all future products with Grove connectors and there are many manufacturers of Grove sensors. And we have the software drivers written for it for the Arduino and the Raspberry Pi on With the software and board, you are ready to go!
