Temperature is the most often-measured environmental quantity. This might be expected since most physical, electronic, chemical, mechanical, and biological systems are affected by temperature. Certain chemical reactions, biological processes, and even electronic circuits perform best within limited temperature ranges. Temperature is one of the most commonly measured variables and it is therefore not surprising that […]

What is a Flame Sensor? A Flame Sensor is a device that can be used to detect presence of a fire source or any other bright light sources. There are several ways to implement a Flame Sensor but the module used in this project is an Infrared Radiation Sensitive Sensor. A flame-sensor is one kind […]

Detection of light is a basic need for everything like plants, animals and even devices. Device researchers have worked on techniques for light detection and developed devices that offer excellent performance. Light is an electromagnetic radiation with a much shorter wavelength and higher frequency than radio waves. It is a quantum mechanical phenomena and comes […]

Infrared technology addresses a wide variety of wireless applications. The main areas are sensing and remote controls. In the electromagnetic spectrum, the infrared portion is divided into three regions: near infrared region, mid infrared region and far infrared region. The wavelengths of these regions and their applications are shown below. Near infrared region — 700 […]
