"Wireless liquid level transmitter application case" water level wireless remote control pump scheme for high reservoir　　　　 One, introduction to the scheme The scheme adopts 433MHz independent wireless communication mode, no running costs, real-time communication, and the use of public GSM network, through SMS to realize remote alarm.Each reservoir is divided into 2 segments, representing 2 different water level heights, using the float state to i

In MVC, Model is not only a data transmitter, but also an mvcmodel. When using a Model, many people use it the same way as when writing a three-tier architecture, and use the Model as the data transmitter. For example, common writing public int Id { get; set; } public int RoleId { get; set; } public string Name { get; set; } public string Password { get; set; } pu

This article describes the development of Android Phone Dialer and SMS transmitter implementation methods. Share to everyone for your reference, specific as follows: Phone Dialer Realization principle: The user enters the telephone number, when clicks dials, by listens for the object capture, listens for the object through the text control obtains to the user to enter the telephone number, because the system has realized the telephone dialing functi

Experience and facts tell us that the advantages of UTP transmission video really enhances our use of twisted-pair video transmitter in the project confidence, but in the actual product purchase and wiring applications, or there will be some problems, to its summary, as follows: 1 in order to enhance the anti-interference ability, use the shielding line Some friends have long been using coaxial lines for transmission, the use of coaxial cable as a t
