electronicsThe TM2291 is an infrared (IR) sensor with SOP-16_150mil packaging and RoHS compliance from Titan Microelectronics. It is an optical sensor that is sensitive to infrared radiation of certain wavelengths. The device can detect infrared energy from a variety of sources, such as flame, natural gas, or industrial liquefied petroleum gas (LPG). It is typically used as a flame detector in fire detection and alarm systems. It has a built-in temperature compensation feature that ensures stable detection over a wide range of temperatures. The device also has an internal timer for wireless transmissions, reducing the need for external timing components. It is designed to provide reliable detection performance at competetive price.
