On Wireless Sensor Networks

Currently, the Internet of Things (IoT), which is extremely popular, 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 problems with precision, stability, and price. Meanwhile, 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 breakthroughs in the research and development of miniature sensors. Only then can wireless sensor networks be widely applied and have practical value. In addition to sensor technology, another pressing issue is the power supply problem. When we change the deployment of sensors from centralized to distributed, the power supply problem becomes a must-solve issue. Although current wireless modules have low power consumption, we still encounter power supply problems due to the lack of miniaturization of sensor modules. Moreover, 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.
