On Wireless Sensor Networks

The Internet of Things (IoT), which is currently a highly popular topic, has not been widely applied despite the maturity of wireless transmission technology. I believe the key issue lies in the underdevelopment of sensor technology. Although there are many miniature sensors available on the market, most of them are still difficult to apply in professional fields due to issues with precision, stability, and price. Moreover, different industries often have their own set of standards for sensors, which typically require high power consumption and are not suitable for wireless sensors. To truly enter the era of wireless sensor networks, we must first achieve a breakthrough in the research and development of miniature sensors. Only then can wireless sensor networks be widely applied and possess practical value. In addition to sensor technology, another pressing issue to be solved is the power supply problem. When we transition from centralized to decentralized deployment of sensors, the power supply problem becomes a must-solve issue. Currently, wireless modules have already achieved very low power consumption, but since sensor modules have not been miniaturized, we still encounter power supply problems. Furthermore, in actual applications, the requirement for system reliability is high. If each node is equipped with a large-capacity battery and solar panel, the cost of each node will increase significantly, which is not practical. Future wireless charging technology and high-efficiency solar panel technology will have a decisive impact on the large-scale application of wireless sensor networks.
