It emits a 10.525 GHz microwave signal and measures frequency shifts caused by moving objects. This makes it suitable for non-contact motion detection, speed measurement, and presence sensing in various embedded projects.\u003c\/p\u003e\n\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\u003e10.525 GHz\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDetection Range\u003c\/td\u003e\n\u003ctd\u003e2–16 m\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSupply Voltage\u003c\/td\u003e\n\u003ctd\u003e4.75V – 5.25V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCurrent Consumption\u003c\/td\u003e\n\u003ctd\u003e30–60 mA typical\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003eAnalog IF signal\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e45 × 37 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eAutomatic door opener systems\u003c\/li\u003e\n  \u003cli\u003eVehicle speed measurement on model roads\u003c\/li\u003e\n  \u003cli\u003ePresence-activated lighting or appliances\u003c\/li\u003e\n  \u003cli\u003eIntruder alarm or security monitoring\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThe HB100 outputs an analog signal that needs amplification before connecting to microcontrollers like Arduino Uno, Nano, ESP32, or Raspberry Pi. It runs on 5V, and the output requires a high-gain amplifier such as the LM358. With proper signal conditioning, it works with motion detection libraries and FFT processing for speed calculation.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect VCC to 5V, GND to ground, and IF to an analog input via an amplifier circuit. The raw IF output is a small AC voltage (~50 mV peak), so use an op-amp with gain around 1000 and a band-pass filter (10–300 Hz) to isolate the Doppler shift. A stable power supply reduces noise.\u003c\/p\u003e\n\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\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino?\u003c\/summary\u003e\u003cp\u003eYes, with an external amplifier. The IF output must be boosted to the 0-5V range for Arduino ADC. Sample code is available to measure frequency changes.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan it detect stationary people?\u003c\/summary\u003e\u003cp\u003eNo, it only detects motion. A person standing still will not produce a Doppler shift. Very fine movements like breathing may be detected with advanced signal processing but typical applications require movement.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat is the detection angle?\u003c\/summary\u003e\u003cp\u003eThe HB100 has a beam width of approximately 72° horizontally and 36° vertically, offering a wide detection zone.\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.
