It reports distance, motion, and static presence data via UART, making it perfect for intelligent automation in homes, offices, and industrial settings.\u003c\/p\u003e\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Frequency\u003c\/td\u003e\n\u003ctd\u003e5.8 GHz\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDetection Range\u003c\/td\u003e\n\u003ctd\u003e0.75 m to 5 m (adjustable)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSupply Voltage\u003c\/td\u003e\n\u003ctd\u003e5 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003eUART (TX\/RX), digital presence pin\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDetection Angle\u003c\/td\u003e\n\u003ctd\u003eApproximately 100° conical\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e24 x 24 mm PCB module\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-occupancy-based-lighting\"\u003eOccupancy-based smart lighting that stays on as long as a person is in the room, even if motionless.\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eEnergy-saving automation to turn off fans, ACs, or monitors when a desk is vacated.\u003c\/li\u003e\n  \u003cli\u003eA security system that triggers an alert or camera when an intruder is present.\u003c\/li\u003e\n  \u003cli\u003ePeople counting and room occupancy dashboard for offices or shops using serial data.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eWorks with any microcontroller that supports 5V logic level UART, such as Arduino Uno, ESP32, or Raspberry Pi Pico. For 3.3V boards like Raspberry Pi GPIO UART, use a level shifter or voltage divider on the sensor’s TX line. Common pairings include ESP32 for Wi-Fi integration and Arduino for rapid prototyping.\u003c\/p\u003e\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect VCC to 5V and GND to ground. Connect the sensor’s TX pin to the microcontroller’s RX pin and RX to TX. The digital presence output goes high when human presence is detected; use a 10kΩ pull-up if needed. Ensure the sensor is mounted with its antenna side unobstructed and away from metal.\u003c\/p\u003e\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Raspberry Pi 4?\u003c\/summary\u003e\u003cp\u003eYes, but the Raspberry Pi’s GPIO UART operates at 3.3V while the sensor outputs 5V. Use a logic-level converter or a simple resistor divider on the sensor’s TX line to avoid damage.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan it detect a person sitting completely still?\u003c\/summary\u003e\u003cp\u003eYes, this sensor emits and analyses reflected microwave signals, so it can detect stationary human presence by sensing micro-movements like breathing. It provides separate ‘moving’ and ‘static’ status outputs.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat is the maximum detection distance?\u003c\/summary\u003e\u003cp\u003eThe sensor can detect presence up to 5 meters, but the firmware allows restricting zones via serial commands. The effective range depends on mounting height and environment.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
