In order to promote the opening and informationization management of laboratory, a set of field controller applied to open laboratory system is designed by using Zigbee and multiple sensors. The controller can collect and report the data of laboratory environmental parameters, lights and running status of curtains, and implement the remote and linkage control on the lights and curtains according to the preset strategy. Open laboratory system composition is introduced. On this basis, the controller hardware structure and realization methods of software and hardware are analyzed and the feasibility and effectiveness of the design scheme are verified by experiment.
