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. 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. 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. Well…For the first time in the history of Grove, we are very excited to bring you a Grove Module based on Radar Technology!
This is the Grove – Doppler Radar.
The Grove – Doppler Radar is based on the BGT24LTR11 Silicon Germanium MMIC which is a 24GHz radar transceiver. It is driven by an XMC1302 MCU based on Arm® Cortex®-M0. 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 through objects and therefore this module does not need to be exposed outside when deploying, but rather behind an object. This, in turn, is extremely useful in security systems. Also, this is able to operate in harsh weather conditions such as high temperatures, dust, and rain.
