24G Millimeter-Wave Radar Module SRR242: Vehicle Fog Lamp Guidance & Stationary Target Ranging/Speed Sensor with 30-Meter Precision Detection
The SRR242 is a high-performance, low-power 24GHz millimeter-wave radar module specifically designed for vehicle fog lamp guidance and stationary target ranging/speed measurement, with a detection range of up to 30 meters. Utilizing Frequency-Modulated Continuous Wave (FMCW) modulation with a one-transmit, two-receive antenna configuration, it accurately detects the distance and azimuth of targets, enabling efficient recognition of moving and stationary vehicles on roadways.
Product Features
- Precise Detection: Measures target distance and azimuth with high accuracy, achieving 0.5-meter range resolution for stationary vehicles.
- Compact Design: Measures just 42mm × 34mm × 5mm, facilitating easy integration and installation.
- Superior Environmental Adaptability: Unaffected by strong light, rain, snow, or fog, with an operating temperature range of -40°C to +85°C for reliable performance.
- Wide Beamwidth: Features a 110° × 80° beam pattern for broad detection coverage and extensive area monitoring.
- Multi-Interface Support: Offers TTL and RS485 communication interfaces, along with 2-channel level control and adjustable 3.3V~12V voltage for flexible secondary development.
