Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the &#8220;Alarm&#8221; pin will go low. This unit works great from 5 to 12 Volt. The alarm pin is an open collector meaning you will need a pull up resistor on the alarm pin. The open drain setup allows multiple motion sensors to be connected on a single input pin. If any of the motion sensors go off, the input pin will be pulled low.<\/p>\n<p>At their most fundamental level, PIR sensor&#8217;s are infrared-sensitive light detectors. By monitoring light in the infrared spectrum, PIR sensors can sense subtle changes in temperature across the area they&#8217;re viewing. When a human or some other object comes into the PIR&#8217;s field-of-view, the radiation pattern changes, and the PIR interprets that change as movement. All that&#8217;s left for us to connect is three pins: power, ground, and the output signal.<\/p>\n<p><strong>DL2401Mk02<\/strong><\/p>\n<p>1 x SparkFun Thing Plus &#8211; ESP32 WROOM<br \/>\n1 x DS3231 Precision RTC FeatherWing<br \/>\n1 x PIR Motion Sensor<br \/>\n1 x Pololu 5V Step-Up Voltage Regulator U1V10F5<br \/>\n1 x Rocker Switch &#8211; SPST<br \/>\n1 x Resistor 10K Ohm<br \/>\n1 x CR1220 3V Lithium Coin Cell Battery<br \/>\n1 x 1 x Lithium Ion Battery &#8211; 1000mAh<br \/>\n1 x Terminal Block Breakout FeatherWing<br \/>\n1 x SparkFun Cerberus USB Cable<\/p>\n<p><strong>SparkFun Thing Plus &#8211; ESP32 WROOM<\/strong><\/p>\n<p>LED &#8211; LED_BUILTIN<br \/>\nSDA &#8211; Digital 23<br \/>\nSCL &#8211; Digital 22<br \/>\nSW1 &#8211; Digital 21<br \/>\nPIR &#8211; Digital 14<br \/>\nVIN &#8211; +3.3V<br \/>\nVIN &#8211; +5V<br \/>\nGND &#8211; GND<\/p>\n<p>&#8212;&#8212;<\/p>\n<p><strong>DL2401Mk01p.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 #28 - Sensors - PIR Motion Sensor - Mk13\r\n28-13\r\nDL2401Mk01p.ino\r\n1 x SparkFun Thing Plus - ESP32 WROOM\r\n1 x DS3231 Precision RTC FeatherWing\r\n1 x PIR Motion Sensor\r\n1 x Pololu 5V Step-Up Voltage Regulator U1V10F5\r\n1 x Rocker Switch - SPST\r\n1 x Resistor 10K Ohm\r\n1 x Lithium Ion Battery - 1000mAh\r\n1 x CR1220 3V Lithium Coin Cell Battery\r\n1 x Terminal Block Breakout FeatherWing\r\n1 x SparkFun Cerberus USB Cable\r\n*\/\r\n\r\n\/\/ Include the Library Code\r\n\/\/ Bluetooth LE keyboard\r\n#include &lt;BleKeyboard.h&gt;\r\n\/\/ Two Wire Interface (TWI\/I2C)\r\n#include &lt;Wire.h&gt;\r\n\/\/ Serial Peripheral Interface\r\n#include &lt;SPI.h&gt;\r\n\/\/ DS3231 Precision RTC \r\n#include &lt;RTClib.h&gt;\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\/\/ DS3231 Precision RTC \r\nRTC_DS3231 rtc;\r\nString dateRTC = &quot;&quot;;\r\nString timeRTC = &quot;&quot;;\r\n\r\n\/\/ PIR Motion\r\n\/\/ Motion detector\r\nconst int iMotion = 14;\r\n\/\/ Proximity\r\nint proximity = LOW;\r\nString Det = &quot;&quot;;\r\n\r\n\/\/ The number of the Rocker Switch pin\r\nint iSwitch = 21;\r\n\/\/ Variable for reading the button status\r\nint SwitchState = 0;\r\n\r\n\/\/ Software Version Information\r\nString sver = &quot;28-13&quot;;\r\n\r\nvoid loop() {\r\n\r\n  \/\/ Date and Time RTC\r\n  isRTC ();\r\n\r\n  \/\/ isPIR Motion\r\n  isPIR();\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.
