Description

technical field [0001] The invention relates to the field of Internet of Things alarms, in particular to an Internet of Things smoke alarm with formaldehyde detection function. Background technique [0002] The smoke alarm realizes fire prevention by monitoring the concentration of smoke. The ion smoke sensor is used inside. The ion smoke sensor is a sensor with advanced technology and stable and reliable operation. It is widely used in various fire alarm systems. It is far superior to the fire alarm of the gas sensitive resistor type. [0003] The infrared beam of the smoke alarm through the infrared emission tube is scattered by the smoke particles, and the intensity of the scattered light is proportional to the concentration of the smoke, so the intensity of the infrared beam received by the photosensitive tube will change and be converted into an electrical signal, and finally converted into The alarm signal and the smoke sensing of the alarm are mainly completed by the...

AI Technical Summary

Problems solved by technology

[0004] Existing smoke alarms can only identify fires through induction pairs, and in some areas, due to special reasons, smoke will also be generated, thereby triggering the smoke alarm, which will cause the smoke alarm to cause false alarms. Thereby delaying the time of firefighters and causing a waste of resources in firefighting
