A photodiode sensor is a semiconductor device that converts light energy into electrical current depending on the device’s mode of operation.
It’s also known as a light detector, photo-sensor, or photo-detector. It may manage small or big surfaces and may include optical filters as well as in-built sensors.
To improve response velocity, photodiode sensors employ a PIN junction rather than a P-N junction. As a result, they perform better and are more genuine. Photodiodes are specifically engineered to work in a reverse bias environment.
In wearable devices like smartwatches and fitness trackers, photodiodes are employed for optical heart rate detection. Photodiode sensors are distinguished by their quick reaction, improved performance, integrated functionality, and excellent dependability.
The demand for photodiode sensors for applications in smartphones such as Ambient Light Sensors and Barcode/QR Code Sensors is increasing as smartphone adoption rises in emerging nations such as India.
The India Photodiode Sensor Market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2026, registering a CAGR of XX% from 2024 to 2030.
Videocon WallCam Introduces a New IP-Based CCTV Series Videocon Wallcam, a fast-growing brand in the security and surveillance space, unveiled its new high-end range of IP-based CCTV solutions at the International Fire & Security Exhibition and Conference (IFSEC) today, backed by Sony STARVIS sensors. This new Videocon WallCam IP based series is aimed to answer the surveillance requirements of Enterprise and Government sectors, and is powered by Sony’s newest CMOS Image sensors -‘ STARVIS’. The entire series will be ‘Made in India.’
Unlike front-illuminated-type image sensors, the picture in the Sony STARVIS image sensor is obtained from the rear side, where there are no barriers such as cabling or circuits, allowing for a broader range of light collection on the photodiode and great sensitivity.
