Brand New Upgrade Underground Remote Monitoring Terminal

Date: 2022-Apr-14

Underground Remote Monitoring


The underground remote monitoring terminal is a portable monitoring device with low power consumption, IP68, wireless communication, and various sensor data collection. It is suitable for the monitoring fields without the power supply condition and the abominable environment. It could realize the mix-used functions including data collection, storage, alarming and transmission for applications of underground water, firework safety, dam leakage, water supply pipeline, especially for underground well application.
