The figure adopts the controller as the capital equipment that digital quantity is gathered and controlled in the on-the-spot monitor system, the stability of the on-the-spot control work to the overall system of its characteristic has very important function. So develop structure to be simple characteristic stable adopting the controller, having very much important meanings by the intersection of reliability and high

with low costs new figure. LM3S101 The microcontroller in order to control the core, and adopt the specialized device SP3485 of RS-485 communication to carry on the design of the communication interface, paid digital input and run side by side / failed by Serial Input / 8 shift registers 74HC164 and parallel entry / 8 shift registers 74HC165 of serial output of parallel output Publish the design method that the expanded figure adopts the controller. It has characteristic such as being strong of relative elevation of the sexual valence, practicality, antijamming capability novel in design that this figure adopts the controller, can apply to various on-the-spot monitor systems extensively, and after transformation, it can apply to the long-distance control system. This figure adopts the hardware of the controller and regards LM3S101 ARM microcontroller as and controls the core, mainly realize functions such as RS485 communication, setting up, local address setting up, gathering and digital flow control of No. 8 of digital quantity of No. 8 of baud rate, etc. The hardware of its system makes up and is shown as in Fig. 1. It adopt figure by that controller control by flow sensors digital live what control centers long-range send out function for instance: The glass breaks and monitors, far infrared monitoring etc. The state that the state controls the order to carry on the sensor digital quantities of No. 8 is gathered, then...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
