Gravity Digital Microwave Sensor Radar / Speed Sensor

This microwave sensor/radar sensor employs the Doppler effect to detect moving objects using microwaves. This type of microwave sensor is commonly used in industrial, transport, and civil applications, such as measuring vehicle speed, fill levels, automatic door motion detection, automatic car wash, material detection on the production line, backup sensors, etc.

The HB100 Radar sensor has the following advantages:

• Contactless detection
• Measurements not affected by temperature, humidity, noise, air, dust, or light, making it suitable for harsh environments
• Strong resistance to high frequency interference
• Low power, safe for humans
• Large detection range and high speed
• Supports the detection of vehicles or other moving objects
