A 5 way flame/heat sensor module is a device that is used to detect the presence of a flame or heat source in a surrounding environment. It consists of a sensor element and a signal processing circuit that is designed to detect the intensity and wavelength of the radiation emitted by a flame or heat source. The sensor element is typically a pyroelectric infrared (PIR) sensor or a thermopile sensor, which are sensitive to the changes in temperature and radiation that are associated with a flame or heat source. The signal processing circuit converts the sensor output into a digital signal that can be read by a microcontroller or other electronic device. The module typically has multiple output options, such as a digital output (high or low) or an analog output (voltage or current), which can be used to trigger an alarm or control other devices.
