This article is about a simple heart rate monitor using 8051 microcontroller. Like the previous 8051 projects, AT89S51 is the microcontroller used here. The device senses the heart rate from the finger tip using IR reflection method and displays it on a three digit seven segment display in beats per minute. The circuit has an accuracy of 4 beats per minute and it is very easy to use. In medical terms, the technique used here for sensing heart rate is called photoplethysmography.

INTRODUCTION
A water meter is a device that is used to measure the volume of water usage.
A prepaid water control circuit system is a control mechanism that allows water usage when there is a certain amount of prepaid units in the control circuit system and terminates water usage when the units are over.
In such a system, a customer purchases a separate prepaid credit card with values of credit units encoded in it.
The un ....etc

Level Sensors Information

Show all Level Sensors Manufacturers
Level sensors are used to detect liquid or powder levels, or interfaces between liquids. They are an important part of a fluid system because the position and displacement of an object or media is critical to know in many applications. The substance to be measured could be inside a container or in its natural form such as a lake or river. A sensor is able to detect a change and communicate that change with a user. Level sensors are generally designed for a specific application, ....etc

A water-fuelled car is an automobile that hypothetically derives its energy directly from water. Water-fuelled cars have been the subject of numerous international patents, newspaper and popular science magazine articles, local television news coverage, and websites. The claims for these devices have been found to be pseudoscience and some were found to be tied to investment frauds.
These vehicles may be claimed to produce fuel from water on board with no other energy input, or may be a hybrid claiming to derive some of its energy from water i ....etc
