| Abstract: | The existing methods and instruments for formaldehyde measurement always have disadvantages such as bad real time capability,tedious steps and weak interconnection.In order to solve these problems,a design procedure for monitoring formaldehyde concentration is mentioned based on the principle of electrochemical reaction.And a corresponding real-time intelligent monitoring system is built based on WiFi module and MSP430F149 MCU,the concentration of formaldehyde of the environment can be accurately measured by this system with a real-time warning,and the current resolution of the response of the sensor has reached to 0.6nA.And remote data transmission can be achieved with excellent practicability.The expected target is realized through experimental results for the system.In further, and the system can be applied in other fields with extended functions. |
