Journal of the institution of engineers (India) Series ASummary: With more and more applications of wireless sensor network technology in intelligent management of greenhouse, high-temperature and high-humidity resistance of wireless sensor nodes are becoming more and more important. This paper takes the wireless sensor nodes of the greenhouse as the research object. Aiming at the characteristics of high-temperature and high-humidity environment in summer, solid–liquid phase change material (stearic acid/lauric acid/graphite powder = 0.18:0.67:0.15) is selected as the cooling solution, the mixed desiccant of silica gel and clay is the dehumidification solution, and the high-temperature and high-humidity resistant shell of wireless sensor node is designed; the COMSOL software is used to simulate the high-temperature and high-humidity performance of the wireless sensor nodes. The results show that the maximum temperature of the node with the shell is kept below 45 °C and the relative humidity is kept within 60.9%; the experimental results of high-temperature and high-humidity environment show that the designed greenhouse wireless sensor nodes have obvious high-temperature and high-humidity resistance and can meet the requirements of wireless sensor nodes working in high-temperature and high-humidity environment of the greenhouse in summer.
