HB100 - Microwave Motion Sensor

Microwave sensor that detects the motion. It is used to detect objects in the premises in alarm systems and lighting systems. The sensor is powered with the voltage from 4.75 to 5.25 V. It works with a frequency of 10,525 GHz.

HB100 - Microwave Motion Sensor.

The sensor uses the Doppler effect to detect movement of objects. Through the use of microwaves instead of IR, it can detect objects that reflect radio waves in the range of micro. In addition, the sensor does not depend on the ambient temperature, it also detects the inanimate objects.

• Non-contact detection
• Reading does not depend on temperature, humidity, noise, air, dust or light - it is great for working in difficult environmental conditions
• High resistance to radio interference
• The signal is harmless to human
• Wide range and high detection speed
• It detects the movement of inanimate objects

The sensor requires an amplifier for the output signal. Therefore, for the read of the frequency, required is to connect the preamp's system to the IF output, according to the patterns in the documentation. Data can be read also with the help of Arduino, after the initial connection of the chip of preamplifier.
