Internet of Things (IoT) technology has recently been widely utilized into a variety of industrial applications. Wireless Passive Surface Acoustic Wave (SAW) sensors have attracted great attention in numerous IoT enabled applications. The sensor nodes are not directly supplied by the power supply as it absorbs the energy from the interrogating Radio Frequency (RF) pulses to excite the SAW. Temperature and pressure are two imperative parameters to monitor whether the pipelines in water distribution system are properly functioning. In this study, the wired and wireless response signals of the passive SAW delay line temperature and pressure sensor is compared. There is a 1/5 attenuation on the response signal when wireless interrogation and response signal receiving process is applied. A wireless passive SAW delay line temperature and pressure sensor was planted in a framework simulating the environment of the water pipelines, and the response signals of the sensor node in different ambient environments are analysed and compared. Compared to the air environment, there is only a sight attenuation of the response signal when the sensor node is planted in the simulating water pipeline environment framework.
