Hardware and Software Development of Multi-channel Environment Parameter Tester

A multi-channel environment parameter tester is developed in order to improve the simple testing function of domestic environment monitoring instrument. Multiple environment parameters can be acquired through multi-channel A/D, FPGA with strong data processing function is selected as the master control to achieve the data processing, and the data is transferred via USB protocol or WiFi/Bluetooth. The test results approves that all channels of multi-channel environment parameter tester designed are working normally, and the environmental data collected is real and believable.
