英文摘要：

This article introduces the theory of the Condensation Sensors and the main parameters of HDP-07, which was used to design a kind of low-power equipment for underwater multi-point leakage detection and alarm system. It also analyzed the theory of how to design the circuit and the basis of calculation. Then it proposed how to set the threshold and multi-point sentencing guidelines. The measured paramet~rs and calibration data were also given. The results show that this program not only have a good performance and detection reliability, but also cost less and the whole system＇s static power is less than 10MW.
