DHT22 Temperature Sensor

I wan't to see temperature and humidity from all of my rooms.I took a look though other users and theire project and decide to use "<a href="https://thingsboard.io/">ThingsBoard</a>" and ESP 8266 nodes. Those nodes are using the deep sleep functionality to save energy. All nodes are running an a small powerbank. DHT22 is used as sensor. I build one seperate sensore with air pressure sensor.Next step will be 3D printethousings to wall mount them.<div class="se-component se-video-container __se__float-none" contenteditable="false" style="width: 100%;"><figure style="width: 100%; height: 56.25%; padding-bottom: 56.25%; margin: 0px;"><iframe frameborder="0" allowfullscreen="" src="https://www.youtube.com/embed/nNAfDx_lGxg" data-proportion="true" data-percentage="100%,56.25%" data-size="100%,56.25%" data-align="none" style="width: 100%; height: 100%;" data-index="0" data-file-size="0" data-origin="100%,56.25%"></iframe><figcaption contenteditable="true"><div>short explanation</div></figcaption></figure></div>Links:Steps to rebuild:1) Install ThingsBoard on Raspberry Pi:<a href="https://thingsboard.io/docs/user-guide/install/rpi/">https://thingsboard.io/docs/user-guide/install/rpi/</a>2) Create a wifi for PI and ESPs (or use existing one)3) Solder ESP like wire diagram (or use bred board) Don't forget the reset bridge from "D0" to "RST" !4) Upload Arduino Code to ESP 8266<ul ><li >ThingsBoard: <a href="https://thingsboard.io/">https://thingsboard.io</a></li></ul><ul ><li >Raspberrry Pi as Server tutorial: <a href="https://thingsboard.io/docs/user-guide/install/rpi/">https://thingsboard.io/docs/user-guide/install/rpi/</a></li></ul><ul ><li >ThingsBoard ESP tutorial : <a href="https://thingsboard.io/docs/samples/esp8266/gpio/">https://thingsboard.io/docs/samples/esp8266/gpio/</a></li></ul>
