The HB100 microwave sensor is a device that is used to detect the presence of moving objects using microwaves. It operates at a frequency of 10.525 GHz and uses the Doppler effect to detect motion. When an object moves within the sensor's detection range, the microwaves that are emitted by the sensor are reflected off the object and received by the sensor's detector. The detector then measures the shift in frequency of the received microwaves, which is caused by the Doppler effect, and generates an electrical signal in response. The electrical signal can be used to indicate the presence of a moving object. The HB100 microwave sensor is often used in applications where it is necessary to detect the presence of moving objects, such as in security systems, automation, and robotics. This module is ideally suitable for intruder detectors. It can also be used for auto-door opening. vehicle speed measurement and even very accurate obstacle detection. This module output a very small 50mA signal an external amp will be required to amplify the signal.
