These two products can detect motion such as proximity, sliding, air sliding TM (gesture waving), zooming in. Real-time processing of object recognition and motion analysis based on simple active infrared optoelectronic technology. Elmos is a gesture in automotive applications. The pioneer of identification, and Elmos is in the world's number one position in this application. One of the reasons is that the product has the best resistance to external ambient light and automatic system calibration in the market. In addition, in order to simplify the system and sensor design, The two products also integrate many important features, making it a plug-and-play solution. The E909.21 has been used in a wide range of vehicle models from leading OEM car manufacturers.
Designed based on the HALIOS® principle, these ICs are based on true optical compensation, which virtually eliminates the parasitic physical effects on the signal receiver side and provides ambient light effects far beyond the capabilities of individual devices. Very good temperature stability. The E909.21 or E909.22 module has 2 receiver channels, 4 LED transmit channels, and a special HALIOS® compensation path. The ICs integrate 100mA current drive for each transmit channel. To eliminate interference with other optical systems, users can set the HALIOS® switching frequency to 1MHz. The integrated 16-bit Harvard architecture CPU can run at variable clock cycles of 4, 8, 12 or 24MHz. In addition, the ICs are also integrated. 32kB flash, 4kB SRAM and 8kB SysROM. The temperature range is -40°C to +85°C. The package for E909.21 is QFN32L5, and the package for E909.22 is QFN20L4.
On request, the device also provides an integrated bootloader that allows programming of the device through one of two serial interfaces (I2C/SPI). In addition, the firmware demo code supports development when generating initialization and calibration routines. Kit. Many application notes and gesture libraries complete the development environment.
