How does a water leak detector work?5 answersA water leak detector works by using various methods to detect the presence of water leaks in pipes or tanks. One method involves using an acoustic sensor to measure the sound of an underground pipeline or the surrounding area, and comparing the measurement value to stored data to determine if there is a water leak. Another method involves using a sound sensor and frequency filters to detect water leakage sounds in different frequency bands, and analyzing the distribution data of the sound levels to determine if water is leaked at multiple points. Additionally, a water leakage detection device can be designed with conductive units and voltage detection circuits to detect changes in voltage caused by water entering a sealed tank, allowing for real-time detection of water leakage. Another approach is to use conductor probes at the bottom of a water purifier to automatically detect water leakage and prevent damage to the internal device. Furthermore, a water leak detection device can combine measurement data from a flow meter and a vibration sensor terminal to determine the result of leakage detection in a water distribution section.

5 answers
Hydrogen transportation via trucks indeed presents capacity limitations compared to pipelines. Trucks are more energy and ecologically intensive than pipeline transportation, despite being more economical for gaseous transport. Pipelines, especially existing natural gas pipelines, offer a more efficient and cost-effective means for long-distance hydrogen transport. Moreover, truck-delivered hydrogen stations have the lowest total investment cost, but liquid hydrogen delivery by trucks incurs high storage costs. On the other hand, hydrogen pipelines can efficiently accommodate supply-demand imbalances via linepack, although pressure fluctuations can lead to faster defect growth, impacting pipeline integrity and lifespan. Therefore, pipelines emerge as a more favorable option for hydrogen transportation due to their higher capacity and cost-effectiveness compared to trucks.How does machine learning and deep learning improve spectrum sensing in CR-IoT systems?
