• Solar powered WiFi weather station

  Michael Wen • 05/14/2015 at 03:21 • 0 comments

  Found a great spot for Solar powered WiFi weather station:

  My deck, it will block the rain, block the sun, and easy to mount solar panel

  Pictures:

  The battery with charging PCB is still naked, I am waiting for the PCB shipment so I can make the Battery Node. Stay tuned.
  

  This is another one in front of my house, it is facing south, so lots of sun shine, 2 sensors will give me both the temperature under the sun or not.

  Steps to make a WiFi weather station:

  1. soldering 90 degree 2.54mm headers onto NodeUSB
  2. Soldering si7021 module on 2.54mm header
  3. If you want to add barometer, Use quick connect wire to add bp180 module
  4. put into case closures
  5. put in USB power adapter

  Here are the pictures:

• Touch Node Video

  Touch node video!

• Universal PCB for modules. (Arduino, etc )

  Michael Wen • 04/21/2015 at 01:15 • 0 comments

  PCB have 8 headers (4 pins, 2.54mm). (With 6 different combinations )

  So you connect different I2C modules (with different pin-outs) in just one Node. For example, you can use it to add both si7021 and bmp180 in your project. Sounds cool?

  Also USB male and female pass-through, you can create Nodes Chain with several nodes!
