RS2111 is an ultra-low power consumption, ultra-small size, ultra-high integration 24GHz 1T1R mmWave radar SoC chip. It integrates 24GHz mmWave radar RF front-end, baseband and application processor. It is specially designed for low-power radar sensing function design. The mmWave radar sensor developed using RS2111 has high-precision ranging capabilities, while achieving precise perception of human motion, micro-motion andpresence.
Its configuration and data collection can be achieved through UART/I2C digital interface with other devices.
• Ultra-Low Power: 4μA+, As same power consumption level as PIR
• Ultra Small Size: 2.5 x 2.5 x 0.55mm³
• High Performance: 8m Long-Distance detection, Anti-Interference algorithm
• Easy Development: No-Code, Plug-and-Play
• Motion/Micro-Motion/Presence Detection
• Doorbells/DoorLocks
• Wall Switch/Panels
• Battery Cameras
• Air Conditioners/Refrigerators/TVs
• Intelligent Lighting
