Vishay Intertechnology has introduced three new miniaturized infrared (IR) sensor modules for remote-control systems. Featuring modulated carrier output for code learning applications, the Vishay Semiconductors dual-lens TSMP95000 and single-lens TSMP96000 and TSMP98000 combine a wide supply voltage range from 2.0 to 5.5 V with a low typical power consumption of 0.35 mA at 3.3 V. Featuring a new in-house…
STMicroelectronics introduces IR sensor for presence and motion detection
STMicroelectronics, a global semiconductor provider serving customers across the spectrum of electronics applications, is launching a novel human presence and motion detector to enhance security systems, home automation equipment, and IoT devices that typically use passive infrared (PIR) sensing. The STHS34PF80 sensor contains thermal transistors that can detect stationary objects, unlike conventional PIR detectors that require the…
Vishay enhances its infrared receiver modules for remote-control applications
Vishay Intertechnology has announced that the company upgraded its TSOP2xxx, TSOP4xxx, TSOP57xxx, TSOP6xxx, and TSOP77xxx series infrared (IR) receiver modules for IR remote-control applications with a new Cyllene 2 IC. Designed in-house to ensure long-term product availability and reduced lead times, the new IC allows designers to achieve higher performance with drastically reduced current consumption over a wider voltage…
STMicroelectronics offers new hybrid sensor for full interior vehicle monitoring
As advanced automotive markets start to mandate driver-monitoring systems (DMS), STMicroelectronics (ST) is equipping carmakers with the required technologies. While DMS promises greater road safety by assessing driver alertness, ST’s next-generation dual-image sensor monitors the full vehicle interior covering the driver and all passengers. ST’s new image sensor is enabling new applications including passenger safety-belt…
New Vishay IR emitters deliver 30% higher radiant intensity
Vishay Intertechnology is broadening its optoelectronics portfolio with the release of six new 850 and 940 nm high-power infrared (IR) emitters that deliver best-in-class radiant intensity in 3.4 by 3.4 mm surface-mount packages. Built on Vishay’s SurfLight surface emitter chip technology, the Vishay Semiconductors devices are designed for high drive-currents up to 1.5 A DC…
Night Vision Technology
‘And then the troops, unnoticed, surrounded whole of the desert city in that dark night, which certainly was all green for them’, we must have come across such lines in some or other war related article. Well, as quite a number of people do know that what does the word “green” here refers to, very few are able to tell the deep insights about it. This article takes every inch of that green and explains its cause, the night vision technology. Night vision technology, as the name suggests, is the expertise that makes us capable to see in the night without using any external light source such as a torch or a lamp. Highly advanced light sensitive cameras are used in this technology that produce clear visible images at night which the naked eye can’t do.
Wireless Communication and types
Wireless communication is among technology’s biggest contributions to mankind. Wireless communication involves the transmission of information over a distance without help of wires, cables or any other forms of electrical conductors. The transmitted distance can be anywhere between a few meters (for example, a television’s remote control) and thousands of kilometres (for example, radio communication). Some of the devices used for wireless communication are cordless telephones, mobiles, GPS units, wireless computer parts, and satellite television. The growth of wireless network has enabled us to use personal devices anywhere and anytime.
Distance measurement using InfraRed sensor with ADC0804 & 8051 microcontroller (AT89C51)
Infrared sensors find numerous applications in electronic systems. Commonly used as obstacle detector, their output is used in digital form (high & low logic) by [[wysiwyg_imageupload::]]employing a comparator. This topic explains a way to use the sensor’s output in its original analog form. Thus, along with detecting an obstacle, its exact distance can also be obtained. This is achieved by processing the output of IR sensor through an ADC0804 (analog to digital converter). The ADC is calibrated to get almost accurate distance measurement.The measured distance is also displayed on an LCD screen. The ADC0804 and LCD are interfaced with 8051 microcontroller (AT89C51) to perform these operations. The major drawback of IR based sensors is their capability of detecting short distances.
