TI IoT Week, Sensor Node Project Part 4

Adding Switched outputs in response to the temperature enabling a Fan to be turned on and off. Celebrating TI IoT week, I am building an IoT node that will monitor the Temperature and Light Levels of wherever you place it. TI products will be as much as possible the heart being a TI Launchpad CC3200. LCD Display and Temperature sensing has been added and today we add the ability to control a Fan by switching a relay via the GPIO pin. providing a level of isolation between the Launchpad and the switch power system. By the end of the week we will have a fully working IoT node that will post the data upto an MQTT server (The Cloud) and provide you with the means to subscribe to that data and present it in a useful way on a Smart device via an HTML5 browser. In this video we will add a fan control so that we can cool things down when the temperature is hot. If you want to replicate this project, it should not cost you more than 50-80$ depending on your current parts and options you choose. The launchpad selected for this project is the CC3200. http://www.ti.com/ww/en/launchpad/launchpads-connected-cc3200-launchxl.html#tabs TI Temperature sensor selected for the project is the TMP275 TMP275 http://www.ti.com/lit/ds/symlink/tmp275.pdf The Display is the 430BOOST-SHARP96 http://www.ti.com/lit/ug/slau553/slau553.pdf and purchased from here http://www.ti.com/tool/430boost-sharp96 or other vendors of your choice I would like to thank Texas Instruments for their support and sponsorship with this project Other videos for this series can be found here:- Day 1 https://youtu.be/im-ip8ZAXjY Day 2 https://youtu.be/QfE8kPg5cWk Day 3 https://youtu.be/feak2L_gM_w Day 4 https://youtu.be/AwO9qjMBsiE Day 5 https://youtu.be/5RdPFRs1cAc Day 6 https://youtu.be/f48pHgzB6VE Day 7 https://youtu.be/fpYWajndIOQ
