illuminance sensor

A lot of sensors are built into the phone, such as: light sensor, humidity sensor, temperature sensor, distance sensor, etc.The development of sensor-related things must use the real machineIn the spiral and accelerometer all two ways push and pull, push way is always detect

Windows operating system has a variety of features, but many features are less used and gradually diluted, such as sensor functions, sensors are hardware components to provide the computer with the environment, location or more relevant information, although the function looks very practical, but now a variety of features are advanced, Turn on the sensor function will occupy the system resources, but also a

First, we need to understand a basic concept: the geomagnetic sensor must work with the gravity sensor, and the compass will work properly.I. Key points for commissioning:1. The gravity sensor has a directivity of 3 axes, and the data output of the geomagnetic sensor is also directional. We must configure the correct p

This article is about Windows Phone 7 development on the 31st day"11th day of the series. Yesterday, we discussed the keyboard of Windows Phone. Today, let's talk about hardware-based acceleration sensors and how to use the information they provide. What is an acceleration sensor? There is no better definition at present. The accelerator sensor in Windows Phone is used to measure the acceleration of three c

Added support for light sensor based on Android 2.2: 1) UI 2) Framework section 3) Hal part 4) Driver The following are discussed respectively: 1) UI A) Enable the brightness setting menu to automatically adjust the brightness checkbox. Frameworks/base/CORE/RES/values/config. xml: - + B) set both the Lux level and the brightness level. Take the 5-level brightness as an example. + 2) Framework sectionA) files related to the framework layer. /CORE/Ja

For an accelerometer, we only need to know its three-axis data, while the android upper layer only needs data in a data structure. 1. About the Linux driver layer The driver registers the input device, reads the three-axis data in the sensor register through the I2C interface, and reports the three data. 2. About the Android hardware abstraction layer There is a sensors. h header file under hardware \ libhardware \ include \ hardware. Fill in a dat

First Arduino default I²c address is 7-bit address, the manual is described, 7-bit address is 0x1e, read address is 0x3d = (7-bit address If you want to communicate with the hmc5883l, you need to hmc5883l power on the 5ms. Therefore, the general write configuration requires a delay of 5ms before communication. After connecting the device to test the sensor, identify the operation and identify register a, identify register B, identify register C is
