Key Features of Microwave Radar Human Body Sensor
- Microwave Doppler Technology: Uses 3.18 GHz radar waves to detect motion - far more reliable than traditional PIR sensors in many environments.
- Through-Wall Detection: Microwave signals penetrate non-metallic materials like wood, glass, and thin plastic, enabling concealed or enclosed mounting.
- 360 degrees Omnidirectional Sensing: Detects motion from all directions around the sensor module without requiring line-of-sight.
- Wide Voltage Input (4V-28V): Operates across a broad voltage range, making it compatible with 5V microcontrollers, 12V systems, and battery-powered setups.
- 3.3V TTL Digital Output: Clean HIGH/LOW signal output directly compatible with Arduino, ESP8266, ESP32, Raspberry Pi, and STM32 boards.
- Ultra-Compact Form Factor: Tiny PCB (~36mm x 17mm) fits easily into enclosures, light fixtures, ceiling panels, and custom housings.
- Low Power Consumption: Draws only ~2.8 mA in standby, suitable for battery-operated and always-on applications.
- Adjustable Sensitivity & Hold Time: Fine-tune detection range and trigger duration by soldering optional resistors and capacitors to onboard pads.
- Light-Dependent Override (CDS Pad): Connect an LDR to the CDS pad to enable daylight-sensing mode - trigger only in darkness for smart lighting.
- No Warm-Up Time Required: Unlike PIR sensors that need 30-60 seconds to stabilize, this radar module is operational almost instantly after power-on.
- Immune to Temperature Interference: Microwave detection is unaffected by ambient temperature changes, wind, or humidity - performs reliably in all climates.
- Simple Integration: Just 3 wires (VIN, GND, OUT) for basic operation - no libraries, protocols, or complex configuration needed.
- Superior to PIR Sensors: Detects subtle and stationary human presence through micro-movements, not just large motion events.
- Hidden Installation Capability: Mount behind walls, inside enclosures, or under countertops - microwaves pass through non-metal barriers.
- Instant Response: No warm-up delay means your automation responds the moment someone enters the detection zone.
- Versatile Voltage Range: Works with everything from 5V Arduino projects to 12V/24V industrial relay systems without additional regulation.
- All-Weather Reliability: Unaffected by temperature swings, drafts, sunlight, or pets (when properly configured), reducing false triggers.
How It Works
The Microwave Radar Human Body Sensor operates on the Doppler effect principle. The onboard transmitter continuously emits low-power microwave
