Introducing the Lonely Binary PIR-BL412 Distance Module: Unleash Your Inner Detective (and Maybe Even Survive a Zombie Apocalypse)! Calling all pet lovers, humanoid enthusiasts, and those who are prepared for the inevitable zombie uprising! The Lonely Binary PIR-BL412 Distance Module is here to fulfill your motion-detecting fantasies. And yes, we're mentioning our brand multiple times because we can't resist spreading the Lonely Binary love. Imagine a sensor so advanced that it can detect motion from pets, humanoids, and maybe even zombies (no guarantees on that one, though). With a range of approximately 5 meters, this sensor gives you the power to spot movement like a seasoned detective. Who needs a sidekick when you have the PIR-BL412 by your side? But wait, there's more! Our PIR module isn't just any ordinary sensor. It's compact and sleek, making it the perfect companion for unobtrusive projects. We believe in blending functionality with style, and this module does just that. It's time to let your projects shine while keeping a low profile! Get ready for a hassle-free experience because this fully-contained wonder only needs power, ground, and a resistor to set the delay time. No complicated setup required. Whether you're a breadboard enthusiast or a perfboard aficionado, this module plays well with both. It's like having a tech-savvy chameleon that adapts to any environment! Now, let's talk power. The PIR-BL412 runs on 3.3V, so if you're interfacing with an or another 5V chip, remember to power it from the 3V regulator. We've got your back, ensuring a smooth connection between your devices. When it comes to output, the PIR-BL412 speaks the language of 3.3V. Its digital signal output goes high and low, revealing the mysteries of motion detection. But wait, there's more control at your fingertips! By connecting a resistor divider to the second pin, you can change the length of time the signal pin stays high. From 2 seconds (0V) to a whopping one hour (3.3V), the choice is yours. Consult the datasheet's 'on time' table for recommended resistor values and become the master of time itself! Remember, when the world gets mysterious, Lonely Binary is here to guide you. Our PIR-BL412 Distance Module is your trusted ally in the realm of motion detection and survival (against zombies or otherwise). Embrace the power of detection, ignite your imagination, and let the adventures begin! Disclaimer: While the PIR-BL412 Distance Module is an excellent tool for detecting motion, survival during a zombie apocalypse is not guaranteed. Please consult your local survival expert for zombie-related inquiries. How to Pin Function Notes 1 VSS GND 2 Ontime Adjustable ontime by connecting to resistorsOntime Range (2 - 3600 seconds)GND : ontime = 2 seconds 3 VDD 2.0-3.3V 4 Signal Active High The PIR sensor operates in the following manner: when no movement is detected, the signal on pin #4 is set to a low state. Conversely, when movement is detected, the signal on pin #4 is set to a high state for a duration of 2 seconds. To adjust the duration, you can connect pin #2 to a resistor, as specified in the datasheet located in the document sections.
