Introduction:

The formaldehyde sensor is an electrochemical sensor that can monitor the formaldehyde concentration in the environment in real time. It has the characteristics of high measurement accuracy, fast response speed, long service life, stability and reliability. We can monitor formaldehyde concentration data online 24 hours a day. We use formaldehyde sensors to monitor formaldehyde concentrations in the environment. So, the sensor monitors that the gas concentration exceeds the set value and issues an alarm signal.

Formaldehyde sensor are mainly used in smart homes, air purifiers, air conditioners and other equipment.

Device structure of formaldehyde gas  sensor ：

The sensor has good sealing, high safety protection level, waterproof and dustproof, to ensure accurate detection results. The installation adopts wall-mounted installation method. We upload data via a SIM card installed inside the device.  So,There is no need for wiring in the house. Portable and efficient to use.

The  sensor has real-time data monitoring, out-of-standard alarm, historical data, and export query. We are using sensors, which can connect to external devices and pass sound and light alarms, SMS alarms and other functions. Our management software can provide the functions of event query, alarm configuration and query, and environment parameter browsing.

Ways to reduce formaldehyde indoors:

​​1. Ventilation method:Formaldehyde is a gas, so air circulation will take away part of the formaldehyde. We increase the air mobility by opening the windows for ventilation, which can reduce the content of harmful substances in the indoor air. And Thus, reducing the harm of such substances to the human body.

2. Removal with activated carbon:We have learned that activated carbon has the advantages of simplicity and cheapness. Activated carbon physically adsorbs formaldehyde without causing secondary pollution and is harmless to the human body. However, this method is suitable for spaces with low formaldehyde content and cannot completely control the long-term release of formaldehyde pollution sources.

3. Use green plants to get rid of:People absorb low-level formaldehyde indoors by using green plants, such as rhizomes and spider plants. This method is suitable for lower concentrations of formaldehyde.
