  • How Does Doppler Radar Technology Work in This Module?

    Doppler radar works by sending a beam of electromagnetic radiation waves from the transmitter (TX Antenna), with a precise frequency, at a moving object.

    Once the electromagnetic radiation wave comes in contact with an object, it travels back towards the receiver (RX Antenna). However, when the wave got reflected from the moving object, the wave now has a different frequency compared to the original frequency, it emitted.

    Then the change in this frequency can be used to calculate the velocity of the moving object.

    More Possibilities for Advanced Users

    The Grove – Doppler Radar module is designed so that the pinouts are broken out from the MCU and the MMIC to enable advanced users to tinker with this module.

    Also, the onboard LED indicators can help users to identify whether the objects are moving towards or away from the module. When the object moves towards the radar, it indicates "NEAR" and when the object moves away from the radar, it shows "AWAY".

    All in all, we believe that the Grove – Doppler Radar will open you to a whole new world of possibilities!
