Aiming at the problems that the convenient household formaldehyde gas detector could not realize simultaneous multipoint detection, excessive warning and the remote monitoring, a kind of indoor formaldehyde gas detection system with wireless AD hoc networking capability was designed. With the Zigbee module CC2530 of TI Company as the core, it adopted the Zigbee network ad-supported capability to realize real-time collection of air quality in multiple rooms at the same time, and uploaded the detected data to Aliyun Internet of Things platform to realize the remote monitoring function. The experimental results show that the system can simultaneously detect the formaldehyde concentration in multiple test points. When the formaldehyde concentration exceeds the preset concentration threshold, the system can make sound and light alarm and release the data to the Internet of Things platform. The remote Internet of Things platform stores the formaldehyde data for PC and mobile terminal to access and check. The system can meet the requirements of indoor formaldehyde concentration detection.
