The technology of data acquisition is the important branch of information science, it not merely employs in intelligent instrument, and in modern industrial production, military science is used widely, no matter proceeding control, condition monitoring, or failure diagnosis, quality detection, all due to data collecting systems. Because one-chip c

omputer powerful and antijamming capability strong and reliability high and flexibility fine developing advantaging such as being easy, have made on the basis of the one-chip computer is a central data collecting system is widely used in a lot of fieldsed. What the data collecting system based on one-chip computer usually adopts is two kinds of methods to realize data acquisition: One kind is to make the collecting part of the data into the plate card to insert in the computer expansion slot and realize data acquisition, namely A/ D switching device is connected with bus interface of the computer directly. Such way based on system integration data collecting system of the computer, can shorten lead time, thus accelerate the job schedule, but the configuration of hardware lacks flexibility, non- portable and using whenever and wherever possible. Another method is to make the collecting part of the data into the independent system, there are one`s own microprocessors, the computer passes serial port and data acquisition unit communication, thus realize data acquisition. The transmission over radio demonstrates very great flexibility in the treatment after data acquisition, save the intricate circuit, can realize easily many people share in real time, so we must launch the continuous data after test out in order to let more persons utilize. Test machine format transmission to want, design one can to carry on wireless emissive...
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.....
