However, when the wave got reflected from the moving object, the wave now has a different frequency compared to the original frequency, it emitted. Once the electromagnetic radiation wave comes in contact with an object, it travels back towards the receiver (RX Antenna). How Does Doppler Radar Technology Work in This Module? ¶ĭoppler radar works by sending a beam of electromagnetic radiation waves from the transmitter (TX Antenna), with a precise frequency, at a moving object.
Maintains operation through harsh weather conditions (temperature, light, dust, rain)Ħ5° / horizontal (-6dB) 22° / vertical (-6dB).High penetration which allows it to be deployed behind an object.ESD protection to avoid system failures caused by ESD strikes.Fast response using electromagnetic waves.24GHz Transceiver MMIC for high-precision measurements.Low power consumption for prolonged usage.Light-weight design, suitable for UAV applications.The first radar-based sensor in the Grove Family.
Also, this is able to operate in harsh weather conditions such as high temperatures, dust, and rain. This, in turn, is extremely useful in security systems. This comes in a compact package and runs on very low power, providing high-precision measurements.The high frequency of this module allows for high penetration though objects and therefore this module does not need to be exposed outside when deploying, but rather behind an object. It is driven by an XMC1302 MCU based on Arm® Cortex®-M0. The Grove – Doppler Radar is based on the BGT24LTR11 Silicon Germanium MMIC which is a 24GHz radar transceiver. Well…For the first time in the history of Grove, we are very excited to bring you a Grove Module based on Radar Technology! Would you believe it? We were tired of using these traditional modules for motion-sensing applications and wanted to deliver you a better solution, integrating new technologies. What if we told you there is an all-in-one module that could do all these functions more precisely and also perform functions such as velocity detection of moving objects and angle detection of objects. How would you build a system that could calculate the distance towards an object or detect whether there is motion present? Normally you would use an Ultrasonic or LiDAR Sensor for distance measurement and PIR Motion Sensor for motion detection.
