With the advancement of sensing technology, different types of rain gauges have emerged, with tipping bucket and piezoelectric designs being particularly common. Tipping bucket rain gauges, due to their stable mechanical structure and easy maintenance, have long been widely used in traditional weather stations. Piezoelectric sensors, on the other hand, are gradually gaining prominence in intelligent monitoring systems due to their high dynamic response and anti-interference capabilities. However, the trade-offs between these two technologies in practical applications, including accuracy, environmental adaptability, and cost, require further exploration. This article will compare these technologies from multiple perspectives, including their principles, advantages and disadvantages, and applicable scenarios, to help users select the optimal solution based on their specific needs.
