nt. In the field of biometrics, we can say quite accurate, offline version, not connected to the computer, plug in the power can be used with every attendance record can be downloaded in two ways, one can download the U disk, another can with a network cable to connect the LAN through a computer to download. Binocular stereo face recognition technology, from indoor lighting effects, the darkness can identify application environment indoor temperature not lower than 0 degrees using distance 30--80cm, compared with fingerprint, face through non contacts, to avoid cross-contact infection, health and safety, and because non-contact, no wear and tear of the machine itself. Using 53-degree angle bevel unique design, installation, 1.15 m from the ground, can be adapted 1.4--2 meters between personnel, solved using different height of the person, recognition speed small one seconds, voice recognition is successful registration, combined with the use of access control, having security record, loop record security coverage, and not by any record through staff time and photo information, you can prepare for post-tracing, you can use wall-mounted on the floor stand, placed on the desktop on the desktop stand three way, mounting height.
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.....
