Description: A frequency modulation (FM) sensor is a device that detects and measures changes in the frequency modulation of a signal. This type of sensor is fundamental in various Internet of Things (IoT) applications, as it allows for efficient data transmission with high quality. Frequency modulation involves varying the frequency of a carrier signal based on the information to be transmitted, resulting in greater resistance to interference and noise compared to other modulation methods. FM sensors can capture these variations and convert them into digital data that can be processed by smart devices. Their design typically includes components such as antennas, demodulation circuits, and microcontrollers, allowing them to easily integrate into larger systems. The relevance of these sensors lies in their ability to facilitate wireless communication in environments where connectivity is crucial, such as in home automation, environmental monitoring, and industrial resource management. In summary, frequency modulation sensors are key tools in the IoT ecosystem, providing an effective way to transmit and receive information in real-time.
