simple human sensor

sensor detects a move and the output is high, if the human body continues to move within the detection range, the sensor remains high, knowing that the person leaves before the delay turns the high level to low.differenceThe difference between the two detection modes, after detecting the movement trigger, if the human

Human infrared module is very simple, is the normal three-pin (vcc,gnd,data), the data is high, low level, that is, there are only two results: High level for the active body is detected, low level for no active human detection. It is important to note that there are several places on the module that can be set: First, the trigger mode:L Non-repeatable, H repeata

This time we have studied the development of Android sensors, previously introduced, tween use, so we can combine sensors with tween animation, develop a simple compass.First of all, introduce the sensor knowledge,in the the use of sensors in Android applications depends on the Android.hardware.SensorEventListener interface. This interface allows you to monitor various events of the

Sensor} Public list Public Boolean registerlistener (sensorlistener listener, int sensors ){Return registerlistener (listener, sensors, sensor_delay_normal );} // Register the listener event Public void unregisterlistener (sensorlistener listener, int sensors) {deregister a listener event} Time relationship: the source code is not mentioned one by one. You can check the source code yourself. If no source code exists, send me an email and I will se

Android practice simple tutorial-62nd guns (electronic Sensor exact Compass) Here we use the sensor provided by the mobile phone to implement a simple small example of the electronic compass. You can learn how to use the SensorManager class, SensorEventListener and its overwriting method. First, create a layout file:

) {Sensormanager.unregisterlistener (listener); }Super. OnDestroy (); }/** * Sensor trigger * / PrivateSensoreventlistener listener =NewSensoreventlistener () { Public void onsensorchanged(Sensorevent event) {floatXValue = Math.Abs (event.values[0]);//X-Axis direction acceleration floatYvalue = Math.Abs (event.values[1]);//Y-Axis direction acceleration floatZvalue = Math.Abs (event.values[2]);//z-axis direction acceleration

Being Simple is actually a very happy and natural thing. In life, in life, there will be little but all kinds of troubles and entanglement, and then there will be all kinds of relaxation and happiness.People do things simply, so they are not complicated. With less distractions and lust, there will be no worries or concerns, and no fraud or intrigue. Without the burden of thinking, people will be relieved, and their hearts will grow wings, and flying w

Java 7: A simple design of the Human Resource Management System, 1. The human resource management system provides the query, add, modify, and delete functions.2. Four methods are provided: Write query, add, modify, and delete. The input data can be saved to the hard disk. The program can be loaded from the hard disk next time.3. Exception Handling and Data Validi

The access process, for example, requires a developer account before a 32-bit key is saved for sending data later. http://www.tuling123.com/Request methodDemo Sample:#-*-Coding:utf-8-*-import urllibimport jsondef gethtml (URL): page = urllib.urlopen (URL) html = page.read () return htmlif __name__ = = ' __main__ ': key = ' 8b005db5f57556fb96dfd98fbccfab84 ' API = '/HTTP/ Www.tuling123.com/openapi/api?key= ' + key + ' info= ' while true:info = Raw_input (' I: ') Request = API +

The access process is as follows, you need to register the developer account, then you will get a 32-bit key, save it for later send data. http://www.tuling123.com/Request methodExample:#-*-Coding:utf-8-*-import urllibimport jsondef gethtml (URL): page = urllib.urlopen (URL) html = page.read () return htmlif __name__ = = ' __main__ ': key = ' 8b005db5f57556fb96dfd98fbccfab84 ' API = '/HTTP/ Www.tuling123.com/openapi/api?key= ' + key + ' info= ' while true:info = Raw_input (' I:
