Key Features

• Microwave radar: 5.8GHz doppler microwave radar
• Good antenna directivity: less volume but better antenna directivity due to the craftsmanship of the antenna.
• Easy for development: UART interface, plug, and read data.
• High sensitivity and precision: MCU built-in intelligent algorithm for wiping out noise interference.

Description

MW0582TR11 - 5.8GHz microwave doppler radar motion sensor is designed by the Maxustech company. This microwave sensor is a microwave module that can transmit the electromagnetic wave of 5.8GHz. It can detect the difference between the transmitted wave and reflection wave to judge whether there is an object moving over the microwave sensor.

In order to get the accurate data from the object, this Doppler radar motion sensor has a self-made patch antenna which has a good antenna directivity. This means the microwave sensor performed well in detecting a specific area. Moreover, this kind of microwave sensor has an MCU inside which include intelligent algorithm to avoid noise gain caused by the device itself. It can also tell apart the environment effect such as moving branch and would not cause false-alarm thanks to the algorithm.

This microwave sensor not only has a sharp “eye” to detect the moving object but also easy to be developed because of its UART interface. As a matter of fact, this microwave sensor can simply plug into the Arduino board or Raspberry Pi through the serial port. Or you can just use a TTL to USB converter module to connect with your PC to read the data. Easy and convenient.

Demo

When using Python SDK, you will get a plot above. If there is a moving object in front of the microwave sensor, there will exist a violent waveform which means the moving object has been detected.
