4. Functionality
The NV-R718PQ operates as a wireless environmental monitoring node within a LoRaWAN network. It continuously measures CO₂ concentration, temperature, and humidity using integrated sensors. The collected data is processed by the internal microcontroller and transmitted periodically to a LoRaWAN gateway. The gateway forwards the data to a network server or cloud-based IoT platform for visualization, analysis, and control.
The device’s solar panel charges the internal battery during daylight, ensuring continuous operation even in low-light conditions. The low-power design allows the sensor to function for extended periods without manual battery replacement. The LoRaWAN communication enables long-range data transmission with minimal power consumption, making it ideal for distributed sensor networks in large buildings or campuses.
