Metal Detector Sensor with Speaker
A Metal Detector Sensor with Speaker is an object microwave detector designed using Doppler radar. Unlike conventional infrared sensors, microwave sensors detect the movement of an object by detecting microwaves reflected from the object. The subject of discovery will not be limited to the human body, and there are many other things. The microwave sensor does not affect the ambient temperature, has a large detection range and high sensitivity, and is widely used in industrial, transport and commercial devices such as vehicle speed, automatic doors, touch lights and parking sensors.
Due to the versatility of Metal Detector Sensor with Speaker, in real-world applications, it will match with another sensor for targeted detection. For example, a microwave sensor infrared pyroelectric sensor, can effectively determine if someone has passed, there will be no sun, was disturbed by the color of clothes, will not respond to other objects.
Features:
- This detection method has the following advantages over other s detection method:
- Contactless detection
- Does not affect temperature, humidity, noise, air flow, dust, light, etc., suitable for harsh conditions
- Protection against radio frequency interference
- The output power is small, does not harm the body structure
- Detection distance
- Support for the detection of non-living objects
- The direction of the microwave oven is very good, the speed is equal to the speed of light
