In line with Sensirion\u2019s industry-proven humidity and temperature sensors, the SHT40 offers consistent high accuracy within measuring range. The SHT40 sensor covers a humidity measurement range of 0 to 100%RH and a temperature detection range of -40\u00b0C to 125\u00b0C. The internal variable power heater enables the device to work properly under extreme operating conditions like condensing environment.<\/p>\n<p>The board supply voltage of 3.3V to 5V and an current consumption below 0.15mA in low power mode make the SHT40 perfectly suitable for mobile or wireless battery-driven applications. It is suitable for urban environment monitoring, intelligent buildings, industrial automation, smart home and other Internet of Things applications.<\/p>\n<p><strong>DL2403Mk04<\/strong><\/p>\n<p>1 x DFRobot FireBeetle 2 ESP32-E<br \/>\n1 x Fermion: SHT40 Temperature &#038; Humidity Sensor<br \/>\n1 x 1 x Lithium Ion Battery &#8211; 1000mAh<br \/>\n1 x Rocker Switch &#8211; SPST<br \/>\n1 x Resistor 10K Ohm<br \/>\n1 x USB 3.1 Cable A to C<\/p>\n<p><strong>DFRobot FireBeetle 2 ESP32-E<\/strong><\/p>\n<p>LED &#8211; 2<br \/>\nRSW &#8211; 17<br \/>\nSDA &#8211; 21<br \/>\nSCL &#8211; 22<br \/>\nVIN &#8211; +3.3V<br \/>\nGND &#8211; GND<\/p>\n<p>&#8212;&#8212;<\/p>\n<p><strong>DL2403Mk04p.ino<\/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 #29 - DFRobot - SHT40 - Mk08\r\n29-08\r\nDL2403Mk04p.ino\r\nDL2403Mk04\r\n1 x DFRobot FireBeetle 2 ESP32-E\r\n1 x Fermion: SHT40 Temperature &amp; Humidity Sensor\r\n1 x 1 x Lithium Ion Battery - 1000mAh\r\n1 x Rocker Switch - SPST\r\n1 x Resistor 10K Ohm\r\n1 x USB 3.1 Cable A to C\r\n*\/\r\n\r\n\/\/ Include the Library Code\r\n\/\/ Bluetooth LE keyboard\r\n#include &lt;BleKeyboard.h&gt;\r\n\/\/ Fermion: SHT40 Temperature &amp; Humidity Sensor\r\n#include &quot;Adafruit_SHT4x.h&quot;\r\n\r\n\/\/ Bluetooth LE Keyboard\r\nBleKeyboard bleKeyboard;\r\nString sKeyboard = &quot;&quot;;\r\n\/\/ Send Size\r\nbyte sendSize = 0;\r\n\r\n\/\/ Fermion: SHT40 Temperature &amp; Humidity Sensor\r\nAdafruit_SHT4x sht4 = Adafruit_SHT4x();\r\n\/\/ Temperature\r\nfloat T;\r\n\/\/ Humidity\r\nfloat H;\r\n\r\n\/\/ The number of the Rocker Switch pin\r\nint iSwitch = 17;\r\n\/\/ Variable for reading the button status\r\nint SwitchState = 0;\r\n\r\n\/\/ Define LED\r\nint iLED = 2;\r\n\r\n\/\/ Software Version Information\r\nString sver = &quot;29-08&quot;;\r\n\r\nvoid loop() {\r\n\r\n  \/\/ Fermion: SHT40 Temperature &amp; Humidity Sensor\r\n  isSHT40();\r\n\r\n  \/\/ Read the state of the Switch value:\r\n  SwitchState = digitalRead(iSwitch);\r\n\r\n  \/\/ Check if the button is pressed.
