Abstract
This paper presents a low-power wireless sensor system scheme for monitoring aviation fuel leakage of depots. Based on MSP430 microcontroller and powered by a combination of lithium battery and solar energy, the system employs the photoionization detection (PID) technology to detect the oil leakage and wirelessly reports the detection results by CC2520 radio-frequency communication module. With a low-voltage PID integrated sensor and a specialized active gas-collecting device, the system can effectively measure the concentration of leakage in low power mode. Furthermore, an integrated temperature sensor is used to compensate environmental temperature influence on the PID sensor. The effectiveness analysis and power estimation of the system show that the proposed scheme is suitable for detecting aviation fuel leakage of depots.
