24GHz Short Distance Speed Sensor & 15m Ir Sensor
This LD1100 24GHz CW radar sensor adopts high-performance I/Q phase detection technology, supporting real-time speed measurement and motion direction identification.
Different from traditional PIR infrared and ordinary microwave sensors, it works all day and night, unaffected by light, rain, fog, dust and temperature changes.
With ultra-thin compact size, low power consumption and global ISM band compliance, it is easy for embedded integration and mass production in smart home, security, automatic door and intelligent lighting systems.
- Speed & Direction Dual Detection, greatly reduce false trigger
- 24.15~24.25GHz Global ISM Band, comply with FCC/RED certification
- 15m Long Detection Distance, 40°×40° Wide Angle Coverage
- Ultra-thin mini size, easy hidden installation for thin devices
- All-weather working, no limitation of day/night and harsh environment
- Low power consumption & wide temperature range -25℃~+55℃
- SMT patch design, convenient for mass SMT production
Product Selling Points
