Aiming at the problem that the existing domestic formaldehyde measurement methods are single and cannot be remotely monitored, a remote real-time monitoring system for indoor formaldehyde concentration based on wireless sensor network ZigBee was designed. The overall system construction scheme was given and the wireless sensor network for formaldehyde concentration detection was constructed. The wireless sensor network for concentration detection realizes real-time measurement of multiple measurement points in the home space through the ZigBee network. After remote transmission through the network, the remote real-time display of data was realized through the LabVIEW monitoring program. After testing, the remote real-time monitoring of indoor formaldehyde concentration at multiple measuring points in the home environment was completed, which verified the feasibility and reliability of the system.
