9 mmWave Radar

mmWave radar has the capability to accurately perceive the presence and status of people within a room, enabling intelligent adjustment of the air conditioning's cooling/heating capacity and air volume. This intelligent adjustment method not only enhances the comfort of the air-conditioning system but also effectively reduces energy consumption, achieving the goal of energy-saving and consumption reduction.

It is worth mentioning that mmWave radar senses targets by emitting and receiving electromagnetic waves, eliminating the need for image or sound information. As a result, there is no risk of privacy leakage. In the current context where users are placing increasing importance on privacy protection, this advantage of mmWave radar undoubtedly provides strong support for its application in smart home products such as air conditioners.

The IWRL6432 mmWave Sensor device is an integrated single chip mmWave sensor based on FMCW radar technology. The device is capable of operation in the 57GHz to 63.9GHz band and is partitioned into mainly four power domains: RF/Analog Sub-System, Front-End Controller sub-System (FECSS), Application Sub-System (APPSS) and Hardware Accelerator (HWA). IWRL6432 is specifically designed to have separate control for each of the above-mentioned power domains to control the states (power ON or OFF) based on use case requirements. The device also features the capability to exercise various low-power states like sleep and deep sleep, where low-power sleep mode is achieved by clock gating and by turning off the internal IP blocks of the device. The device also provides the option of keeping some contents of the device, like Application image or RF profile retained in such scenarios.
