Introduction

Formaldehyde (HCHO) is a colorless, flammable, and strong-smelling chemical widely used in building materials and household products. Its presence in indoor environments is concerning, as it can be released into the air over extended periods ranging from 3 to 15 years. Elevated emissions of formaldehyde are commonly associated with higher temperatures and humidity levels, making it a persistent challenge in maintaining healthy indoor air quality.

Exposure to formaldehyde can lead to various health issues. Short-term exposure may cause symptoms such as nausea, skin irritation, and burning sensations in the eyes, nose, and throat. Prolonged exposure to high levels of formaldehyde is more dangerous and has been linked to cancer in humans, as identified by the International Agency for Research on Cancer (IARC), which classifies formaldehyde as a human carcinogen.

In response to these risks, formaldehyde sensors have become crucial tools for detecting and mitigating the presence of this harmful compound in indoor environments.

What Are Formaldehyde (HCHO) Sensors?

Formaldehyde sensors are sophisticated devices designed to monitor and measure the concentration of formaldehyde in the air. These sensors play a vital role in detecting harmful levels of formaldehyde, ensuring that indoor environments remain safe and conducive to health.

Modern formaldehyde sensors are equipped with advanced technology, enabling them to provide accurate, real-time measurements. They are often integrated into air quality monitoring systems to enhance their functionality and effectiveness.
