UVTRONs are ultraviolet ON/OFF detectors that can quickly detect a flame’s weak UV emission from a distance, making them suitable for flame detectors and fire alarms. They are completely insensitive to visible light.
Photo IC sensors designed specifically for flame detection (flame eye) in oil-fired hot water boilers and heaters. Since they don’t use conventional CdS cells, these products are RoHS compliant.
Low-cost sensors that generate thermoelectromotive force in proportion to the energy level of incident infrared light. Concentration of various types of gases can be measured by attaching a band-pass filter to thermopile detectors.

For modern websites to work according to visitor’s expectations, they need to collect certain basic information about visitors. To do this, a site will create small text files which are placed on visitor’s devices (computer or mobile) - these files are known as cookies when you access a website.
