HB100 Microwave Motion Sensor

This Microwave Motion Sensor is ideal for alarms, motion detectors, lighting control, vehicle speed measurement and automatic doors.

Features:

• Low current consumption (typical 30 mA)
• CW or pulse operation
• Long detection range (20 m)
• Supply voltage: between 4.75V and 5.25V
• X-Band frequency: 10.525 GHz
• Minimum Power Output: 13 dBm EIRP
• Can be calibrated to detect motion through glass / acrylic / thin walls
• Detection Angle: approx 180 degrees
• Frequency depends on the speed of movement
• Output has a DC offset
• Coupling capacitor required before the amplifier

Note: Use caution when soldering and connect the device to a reliable ground wire as this device is sensitive to static. The IF pin is especially sensitive and can be checked for damage using a multimeter in diode mode. The forward voltage drop between IF and GND should be about 0.25 V.
