24.125GHz Microwave Radar Sensor with 4m×2m Wide Detection
Our 24.125GHz Microwave Radar redefines reliability for automatic door and commercial access motion sensing. Equipped with 4m × 2m wide detection and 12-24V universal voltage support, this advanced sensor uses microwave Doppler technology to emit 24.125GHz signals with controlled power density (≤5mW/cm) and radiated power (<20 dBm EIRP), complying with R&TTE and EMC international standards for safe, interference-free operation.
The optimized detection field covers the full access area of most commercial and sliding glass doors, capturing human motion accurately from all entry angles. The 12-24V AC/DC wide voltage range makes this sensor a universal fit for global commercial and industrial applications.
Product Highlights
24.125GHz mainstream microwave frequency for stable motion detection (≥5cm/s)
Wide detection field: 4m(W)×2m(D) at 2.2m mounting height

Installation & Adjustment Guide
The sensor's performance is closely related to correct installation and adjustment—simple operation with no professional tools required:
Mounting Requirements: Avoid vibration positions, neon lamp proximity and sensor occlusion; do not touch internal electronic parts during installation.
Sensitivity Adjustment: Rotate the sensitivity potentiometer gently and slowly; the sensitivity value determines the size of the detection field.
Angle Adjustment: Planar antenna lateral angle = detection field position; vertical angle = detection field depth; set microwave module angle to ≥45° for optimal detection.
Status Check: LED flashes after power-on (normal standby); LED lights up continuously when a moving target is detected.
Troubleshooting Guide
Fault Phenomenon
Probable Causes
Corrective Action
Door does not open & LED no light
Sensor power off
Check wiring connection and power supply validity
Door opens/closes constantly
Sensor detects door vibration/movement; interference source in detection range
Industrial Automation: Conveyor belt motion detection, equipment start/stop induction (light industry production lines)
Intelligent Building: Smart lighting induction, air conditioning induction (public areas such as corridors and elevators)
