What Is a Wireless Sensor Node?
A wireless sensor node is a compact, wireless device designed for monitoring environmental or system conditions.
It is equipped with various sensors, including those for temperature, humidity, light, sound, and vibration, allowing it to collect data and transmit it wirelessly. Wireless sensor nodes find applications in diverse fields such as smart homes, smart cities, and industrial automation.
Key components of a wireless sensor node include sensors, microcontrollers, and wireless modules. Various communication protocols, such as ZigBee, Wi-Fi, and Bluetooth, are used, each offering specific advantages. ZigBee is known for its low power consumption and suitability for long-distance communication, Wi-Fi excels in high-speed data transfer, while Bluetooth is ideal for short-range communication.
