This work aims to design an environmental monitoring system with high reliability that can monitor real-time temperature, humidity, acceleration in the storage and transportation process, collect data and record time. Finite element impact simulation was conducted on the circuit and shell by finite element analysis software Ansys. The maximum deformation of the shell was 0.03 mm and the Von Miss equivalent stress was 25.5 MPa under the impact effect. That proved the shell had shock resistance reliability. The results of PCB modal analysis proved that the circuit board could reliably work under the environmental impact. In conclusion, the designed environment monitoring system in storage and transportation has good reliability.
