It features standard I2C interface and a wide voltage supply of 2 Volt &#8211; 5 Volt. And with simple peripheral circuit, it performs stably even in harsh environments in the measuring range of -40 &#8211; +85 Celsius. This sensor can be widely used for measuring the environmental temperature and humidity of home electronic equipment, the temperature and humidity of automobiles and so on.<\/p>\n<p><strong>DL2504Mk03<\/strong><\/p>\n<p>1 x UNIHIKER K10<br \/>\n1 x Lithium Ion Battery &#8211; 1000mAh<br \/>\n1 x Switch<br \/>\n1 x USB 3.1 Cable A to C<\/p>\n<p><strong>DL2504Mk03p<\/strong><\/p>\n<p><strong>DL2504Mk03p.mp<\/strong><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"arduino\" data-enlighter-title=\"\">\r\n\/****** Don Luc Electronics \u00a9 ******\r\nSoftware Version Information\r\nProject #30 - UNIHIKER - AHT20 - Mk09\r\nDL2504Mk03p.mp\r\nDL2504Mk03\r\n1 x UNIHIKER K10\r\n1 x Lithium Ion Battery - 1000mAh\r\n1 x Switch\r\n1 x USB 3.1 Cable A to C\r\n*\/\r\n\r\n\/\/ Include the Library Code\r\n\/\/ Unihiker K10\r\n#include &quot;unihiker_k10.h&quot;\r\n\/\/ Arduino Image Cache\r\n#include &quot;arduino_image_cache.h&quot;\r\n\r\n\/\/ Create an object\r\n\/\/ UNIHIKER K10\r\nUNIHIKER_K10 k10;\r\n\/\/ Screen\r\nuint8_t screen_dir=2;\r\n\/\/ AHT20\r\nAHT20 aht20;\r\n\r\n\/\/ Software Version Information 30-09\r\n\/\/ Main program start\r\nvoid setup() {\r\n\t\r\n  \/\/ Begin\r\n  k10.begin();\r\n  \/\/ Init Screen\r\n  k10.initScreen(screen_dir);\r\n  \/\/ Canvas\r\n  k10.creatCanvas();\r\n\r\n}\r\n\/\/ Loop\r\nvoid loop() {\r\n\r\n  \/\/ Draw Bitmap\r\n  k10.canvas-&gt;canvasDrawBitmap(0,0,240,320,image_data1);\r\n  \/\/ Text TEMPERATURE (C)\r\n  k10.canvas-&gt;canvasText(&quot;TEMPERATURE (C)&quot;, 6, 0x330000);\r\n  \/\/ Text AHT20 TempC\r\n  k10.canvas-&gt;canvasText(aht20.getData(AHT20::eAHT20TempC), 7, 0x0000FF);\r\n  \/\/ Text HUMIDITY\r\n  k10.canvas-&gt;canvasText(&quot;HUMIDITY&quot;, 8, 0x330000);\r\n  \/\/ Text AHT20 HumiRH\r\n  k10.canvas-&gt;canvasText(aht20.getData(AHT20::eAHT20HumiRH), 9, 0x0000FF);\r\n  \/\/ Update Canvas\r\n  k10.canvas-&gt;updateCanvas();\r\n\r\n}\r\n<\/pre>\n<p>&#8212;&#8212;<\/p>\n<p><strong>People can contact us:<\/strong> https:\/\/www.donluc.com\/?page_id=1927<\/p>\n<p><strong>Electronics, IoT, Teacher, Instructor, R&#038;D and Consulting<\/strong><\/p>\n<ul>\n<li>Programming Language<\/li>\n<li>Single-Board Microcontrollers (PIC, Arduino, Raspberry Pi, Arm, Silicon Labs, Espressif, Etc&#8230;)<\/li>\n<li>IoT<\/li>\n<li>Wireless (Radio Frequency, Bluetooth, WiFi, Etc&#8230;)<\/li>\n<li>Robotics<\/li>\n<li>Automation<\/li>\n<li>Camera and Video Capture Receiver Stationary, Wheel\/Tank and Underwater Vehicle<\/li>\n<li>Unmanned Vehicles Terrestrial and Marine<\/li>\n<li>Machine Learning<\/li>\n<li>Artificial Intelligence (AI)<\/li>\n<li>RTOS<\/li>\n<li>Sensors, eHealth Sensors, Biosensor, and Biometric<\/li>\n<li>Research &#038; Development (R &#038; D)<\/li>\n<li>Consulting<\/li>\n<\/ul>\n<p><strong>Follow Us<\/strong><\/p>\n<p><strong>Luc Paquin \u2013 Curriculum Vitae &#8211; 2024<\/strong><br \/>\nhttps:\/\/www.donluc.com\/luc\/<\/p>\n<p><strong>Web:<\/strong> https:\/\/www.donluc.com\/<br \/>\n<strong>Facebook:<\/strong> https:\/\/www.facebook.com\/neosteam.labs.9\/<br \/>\n<strong>YouTube:<\/strong> https:\/\/www.youtube.com\/@thesass2063<br \/>\n<strong>Twitter:<\/strong> https:\/\/twitter.com\/labs_steam<br \/>\n<strong>Pinterest:<\/strong> https:\/\/www.pinterest.com\/NeoSteamLabs\/<br \/>\n<strong>Instagram:<\/strong> https:\/\/www.instagram.com\/neosteamlabs\/<br \/>\n<strong>Patreon:<\/strong> https:\/\/patreon.com\/DonLucElectronics59<br \/>\n<strong>DFRobot:<\/strong> https:\/\/learn.dfrobot.com\/user-10186.html<br \/>\n<strong>Hackster.io:<\/strong> https:\/\/www.hackster.io\/neosteam-labs<br \/>\n<strong>Elecrow:<\/strong> https:\/\/www.elecrow.com\/share\/sharepj\/center\/no\/760816d385ebb1edc0732fd873bfbf13<br \/>\n<strong>TikTok:<\/strong> https:\/\/www.tiktok.com\/@luc.paquin8<br \/>\n<strong>Twitch:<\/strong> https:\/\/www.twitch.tv\/lucpaquin<br \/>\n<strong>Hackster:<\/strong> https:\/\/www.hackster.io\/luc-paquin<br \/>\n<strong>LinkedIn:<\/strong> https:\/\/www.linkedin.com\/in\/jlucpaquin\/<\/p>\n<p><strong>Don Luc<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>&#8212;&#8212; #DonLucElectronics #DonLuc #AHT20 #UNIHIKER #Display #IoT #Project #DFRobot #Fritzing #Programming #Electronics #Microcontrollers #Consultant &#8212;&#8212; &#8212;&#8212; &#8212;&#8212; &#8212;&#8212; AHT20 &#8211; Temperature and Humidity Sensor The AHT20 is a high-precision but low-cost temperature and humidity sensor, which is equipped with an improved MEMS semiconductor capacitive humidity sensor element.
