Problems solved by technology

[0003] The existing formaldehyde detector alarm device consumes too much power due to the defects in its system design. If the alarm device is powered only by the formaldehyde detector's own power supply, its overall running time will not exceed 3 hours, so it is convenient Greatly affected the normal operation of the formaldehyde detector
In addition, the stability of the system operation of the alarm system is poor, and it is easy to be damaged during operation, which increases the cost of product use and increases the burden on users
