Description
Grove Doppler Radar (BGT24LTR11) 24GHz TransceiverThe 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 of objects' movement and speed. Features The first radar based sensor in the Grove Family Compact size for easy deployment Light weight design, suitable for UAV applications Low power
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 of objects' movement and speed.
Features
- The first radar-based sensor in the Grove Family
- Compact size for easy deployment
- Light-weight design, suitable for UAV applications
- Low power consumption for prolonged usage
- 24GHz Transceiver MMIC for high-precision measurements of movement and speed
- Fast response using electromagnetic waves
- ESD protection to avoid system failures caused by ESD strikes
- High penetration which allows it to be deployed behind an object
- Maintains operation through harsh weather conditions (temperature, light, dust, rain)
How Does Doppler Radar Technology Work?
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. We also provide you with a built-in function getSpeed() which helps you easily get the moving speed of the object you are targeting. Detailed information can be found on the product's wiki page .
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".
