APDS-9006-020 Second, we observed that the light sensor of modern smartphones also captures the red, green, blue, and white (RGBW) intensities which leaks even more in-formation and improves the accuracy of the attack. ALS (Ambient Light Sensor) is located on the top right corner of the keyboard (shown below). Burhani Tools Centre. Ultrasonic waves can detect transparent objects such as transparent films, glass bottles, plastic bottles, and plate glass, using its Reflective Sensors. Popular Services like Ola, Uber, Zomato and Swiggy use GPS Feature. This sensor can also detect if the display of the phone is in upward or downward position. A proximity sensor detects when the the phone is held to the face to make or take a call, so the touch screen display can be disabled to avoid unintended input. The automatic light sensor circuit can be used for controlling the electrical appliances such as light, fan, cooler, air conditioner, street light, etc., automatically. And while GPS doesn’t use up data, all this communicating and calculating can be a drain on your battery, which is why most battery-saving guides recommend switching GPS off. These Sensors can read Barcodes on Product Packaging and QR Codes. This data can be used in several useful ways. In voltage comparator mode, the OpAmp compares the voltage levels between its inverting input (pin2) and the non- inverting input(pin3) and gives an appropriate high / low output. A light sensor detects data about lighting levels in the environment to adapt the display accordingly. 4.
