Silicon Photodiodes or Photo ICs together with an Infrared LED are used for rain sensors, to detect water on the windshield. The rain sensor integrates an Infrared LED, which sends out light pulses to the windshield, and an optical sensor, where the light is reflected to, back from the windshield.

If the windshield is dry, most of the light is reflected back onto the sensor. If there is water on the windshield, a part of the light is refracted into different directions and therefore less light is reflected back to the sensor.

The sensor signal is checked by an ASIC in the rain sensor or in a central control unit and if it drops beneath certain thresholds, the rain sensor activates the wipers at the appropriate speed. The location of the rain sensor module is usually behind the rear view mirror but other locations are also possible.

Our Photodiodes and Photo ICs are available with analog or digital output. We also offer the components in different packages, such as TO packages for high reliability, hermetic sealing and good aligning precision, or SMD packages for small package sizes and standard reflow soldering.

As airbags are one-time use only and have to be replaced in the garage after deployment, this system also helps to save money. It avoids unnecessary airbag deployment, for example, in seats where there are no passengers and therefore avoids the need to replace them.

Besides airbags, occupant detection and monitoring is also necessary for other advanced driver assistance systems (ADAS). Some cars, for example, use seat-belt tightening as a pre-crash safety measure in the case of an accident, which requires occupant information. In addition, fatigue detection can be performed by monitoring eye movements and blinking frequency using a camera. Monitoring the driver’s activity becomes an important topic when considering the future direction to automated driving, as the driver will be allowed to do other things besides the actual driving task, such as reading or working with a tablet. It is therefore crucial that the take over time from automated driving mode to manual driving will be short enough, in case of an emergency situation, if the system is not completely autonomous.

Our TOF CMOS sensor works with an indirect time of flight (TOF) measurement as a 3D sensor. It can therefore deliver the information about the occupants’ position or about the driver’s activity or fatigue. An infrared laser diode or LED, or an array of these, is used as active illumination and sends out short light pulses. The CMOS sensor determines the time of flight of the reflected, incident light with each of its pixels, creating a 3D picture. This CMOS sensor is a special, high-speed charge transfer device, which is essential to measure short distances. The light pulse travels with a high speed of 3*108 m/s to the object and back. The closer the object, the shorter is the time of flight. Therefore the detector must be able to do the whole measurement within several nanoseconds.
