It is developed that the ones that assist driving system intelligent improvement and car electronic system that demand to the car as people are networked, new radar for back running vehicle should can serial range finding and reveals the distance of obstacle, and have communication functions, can send the data to the bus line of car. The past radar for back running vehicle designs components and parts

used to be more, the function is relatively simple too. The radar for back running vehicle on the basis of the new high performance ultra low power consumption one-chip computer MSP430F2274 that this text introduces can remedy the deficiency of the past products. The overall design system of system adopts the ultrasonic range finding principle. The ultrasonic range finding instrument is generally made up of projector, receiver and part of signal processor three. While working, the ultrasonic transmitter sends out the supersonic pulse, the ultrasonic receiver receives and meets the backward wave that obstacles reflected back, measure supersonic wave and reflect the time to return from launching to meeting obstacles accurately, according to the ultrasonic propagation velocity, can calculate the distance of obstacles. As a non-contact type detection mode, supersonic wave have the intersection of air and the intersection of propagation attenuation and light, reflecting capacity and the intersection of penetrability and better characteristic. Ultrasonic range finding does not is influenced by light and sleet fog, bes simple in construction, makes convenient and cost low grade advantage within the range of close quarter. The high-performance one-chip computer combines ultrasonic range finding, can realize the powerful radar for back running vehicle easy to use. 16 one-chip computer MSP430F2274 power consumption of TI Company are...
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.....
