10.525GHz Microwave Radar Sensor HB100
This HB100 microwave sensor is easy to use because it can be connected directly to a microcontroller. A "bare" HB100 sensor requires an amplifier to amplify the signal and this module has it build=in already. It is ideal to be used with a microcontroller because no other external components are required.
The microwave motion sensor is a microwave moving object detector designed using the Doppler radar principle. Unlike ordinary infrared detectors, microwave sensors detect the motion of an object by detecting microwaves reflected from the object. The detection will not be limited to the human body. The microwave sensor is not affected by the ambient temperature, has a long detection range and high sensitivity, and is widely used in industrial, transportation, and civil devices such as vehicle speed, automatic doors, sensor lights, parking sensors and even burglar alarm sensors.
Features:
- Non-contact detection
- It is not affected by temperature, humidity, noise, airflow, dust, light, etc., and is suitable for harsh environments
- Strong anti-radio interference capability
- The output power is small, which is not harmful to the human body
- Far detection distance
- Support for detection of non-living objects
- The directionality of the microwave is very good, and the speed is equal to the speed of light
