With the rapid development of technology, sensor technology has become an indispensable core component of modern environmental appliances. They can accurately measure and perceive various physical quantities in the environment, such as temperature, humidity, pressure, light intensity, sound, and gas concentration, and convert these physical quantities into electrical signals for digital processing and analysis. This article will delve into commonly used sensors in environmental appliances, including carbon dioxide sensors, formaldehyde sensors, dust sensors, and temperature and humidity sensors, and reveal their important roles in improving product intelligence and providing a healthy and comfortable living environment.

Carbon dioxide sensor

Carbon dioxide sensors can monitor indoor carbon dioxide concentration in real time and automatically adjust the amount of fresh air introduced or the working mode of air purifiers according to changes in concentration, thereby maintaining fresh indoor air. High concentrations of carbon dioxide may cause symptoms such as dizziness and drowsiness, therefore, the application of carbon dioxide sensors is of great significance for improving indoor air quality. Common carbon dioxide sensors include the low concentration infrared carbon dioxide sensors COZIR-LP3 and COZIR-A from the British brand GSS, which can achieve high-precision measurement at low power consumption and are widely used in fresh air systems and air purifiers.

Formaldehyde sensor

Formaldehyde, as one of the main sources of indoor air pollution, poses a serious threat to human health. Therefore, the application of formaldehyde sensors is particularly important. Formaldehyde sensors can accurately measure indoor formaldehyde concentration and promptly alarm when the concentration exceeds the standard. At the same time, they can be linked to air purifiers or fresh air systems to effectively reduce formaldehyde concentration and ensure residential health. The Japanese NEMOTO electrochemical formaldehyde sensor NE-HCHO-S and the German EC Sense formaldehyde sensor TB600C-HCHO-100 both have the characteristics of high sensitivity, high accuracy, and long lifespan, which can monitor indoor formaldehyde concentration in real time and provide safety protection for users.

Dust sensor

Dust sensors can monitor indoor dust concentration in real-time, providing accurate data support for air purifiers to more efficiently remove allergens such as indoor dust and pollen, and reduce the occurrence of respiratory diseases. The Japanese SHARP PM2.5 dust sensor GP2Y1010AU0F is an optical air quality sensor that can detect the reflected light of dust in the air, even very small particles can be detected. This sensor is widely used in products such as air fresheners, ventilation air conditioners, and ventilation fans, effectively improving indoor air quality.

Temperature and humidity sensor

Temperature and humidity sensors can monitor changes in indoor temperature and humidity in real time, and automatically adjust the working mode of humidifiers, air conditioners, and other equipment according to user needs, thereby maintaining appropriate indoor temperature and humidity and improving living comfort. The French Humirel digital output temperature and humidity sensor HTU21D, capacitive humidity sensor HS1101LF, and Korean Samyoung temperature and humidity sensor module HTW-211 all have high precision, low power consumption, and long-term stability, and are widely used in temperature and humidity instruments, office automation, household appliances, and industrial process control systems.

Future prospects of sensor technology

With the advancement of technology and the improvement of people's health awareness, sensor technology in environmental appliances will continue to upgrade. In the future, sensors will become more intelligent and networked, capable of real-time monitoring and feedback of a wider range of environmental parameters, providing users with more accurate and personalized environmental control solutions. At the same time, the combination of sensors with technologies such as the Internet of Things and big data will drive the development of environmental appliances towards a more intelligent and efficient direction, bringing more surprises and convenience to modern home life.

In summary, sensors, as the core components of environmental appliances, play a crucial role in improving product intelligence and providing a healthy and comfortable living environment. In the future, with the continuous advancement and innovation of sensor technology, environmental appliances will bring users a more intelligent, healthy, and comfortable living experience.
