A simple demo

You can build an IoT application easily with Grove modules supplied in this kit. Now we use some Grove modules supplied to build a demonstrative IoT application, which is used to collect data from sensors in house and control home appliances. To be specific, this demonstrative application achieve following functions:

  • Collect data on illumination strength, ambient temperature and humidity and display them on OLED screen, these data also can be accessed from a cloud server.
  • Use a relay to connect a desk lamp, with which you can switch the lamp with a control or switch the lamp with a button from the cloud server.

Help us make it better

Thank you for choosing Seeed. A couple of months ago we initiated a project to improve our documentation system. What you are looking at now is the first edition of the new documentation system. Comparing to the old one, here is the progresses that we made:

  • Replaced the old documentation system with a new one that was developed from Mkdocs, a more widely used and cooler tool to develop documentation system.
  • Integrated the documentation system with our official website, now you can go to Bazaar and other section like Forum and Community more conveniently.
  • Reviewed and rewrote documents for hundreds of products for the system’s first edition, and will continue migrate documents from old wiki to the new one.

An easy-to-use instruction is as important as the product itself. We are expecting this new system will improve your experience when using Seeed’s products. However since this is the first edition, there are still many things need to improve, if you have any suggestions or findings, you are most welcome to submit the amended version as our contributor or give us suggestions in the survey below, Please don’t forget to leave your email address so that we can reply.

Happy hacking
