Ventilation

Winsen Technology has provided accurate gas detection solutions for more than 1,000 fresh air enterprises, which has also established the influence of Winsen sensors in the air purification market. In the future, Winsen will launch more intelligent and miniaturized all-in-one integrated modules to meet the various needs of different customers in the ventilation system market.

A popular solution to indoor air pollution - ventilation system

sensor for Ventilation

The ventilation system is a set of independent air handling systems composed of air supply and exhaust systems. In simple terms, the ventilation system fan can be regarded as the "breathing system" of the house. When it is installed, the house can breathe on its own. In a breath, keep the indoor healthy and comfortable air at all times, and enjoy the fresh air of nature without opening the window.It can avoid "air conditioning disease", recover indoor temperature and humidity, save heating costs, effectively eliminate indoor bacteria and viruses, reduce indoor carbon dioxide concentration and dustproof, and is currently a very popular indoor air pollution solution.

In the intelligent ventilation system, the real-time detection of the air state is realized by adding detection sensors to the host system (such as the dust sensor at the front end of the filter screen), linkage control, that is controlling the operation of the ventilation system fan according to the monitoring data.

The key to the exchange of fresh air: CO2 sensor

sensor for Ventilation

The main function of the sensor in the building automation system is to make the whole building safer, energy efficient and comfortable. The CO2 sensor, like the temperature and humidity sensor and other sensors, belong to the bottom layer. They send their measured values to the data collector through digital or analog signals. After that, it is transmitted to the central processing unit through the data collector. The central processing unit controls the actions of each device through the controller. Through the central processing unit, the main function of the CO2 sensor is to adjust the fresh air volume in the building, and to control the exchange of fresh air by controlling the carbon dioxide content, so that the environment maintains the best comfort level, and the operating cost is minimized, save energy consumption of air conditioners and ventilators. This also slows down the consumption of environmental energy and the increased global greenhouse effect.

Winsen best-selling air quality detection module: ZPHS01

Winsen established a special R&D team to develop a high-end air quality detection module specially designed for air quality detection and very suitable for use in fresh air systems: ZEHS01. It is an all-in-one sensor module integrating electrochemical formaldehyde sensor (or VOC sensor), pm2.5 dust sensor, infrared CO2 gas sensor and temperature and humidity sensor. This product is small in size and has the characteristics of good consistency, stability, accuracy and multi-detection intelligence. It is very convenient to integrate into purifiers and ventilation system, can intelligently sense changes in air quality, and display the collected values of PM2.5, carbon dioxide, formaldehyde (or VOC), temperature and humidity in real time. (Note: The formaldehyde sensor can be replaced with a VOC sensor according to customer needs)

▲ ZPHS01 air quality detection module

ZPHS01 all-in-one sensor module has developed a variety of external communication interface methods such as RS485, serial TTL, IIC, etc., and adopts isolated power supply and isolated 485 module to ensure stable operation of the module in complex scenes; The built-in standard MODBUS-RTU communication protocol realizes the master-slave control mode of bus communication,and the customer's host device can connect up to 256 modules as slave devices to realize distributed air quality detection and flexible sensor layout. The product is truly designed from the perspective of customer experience, and intelligent integration makes everything simple. For some customers who are not very proficient in sensors, it is also easy to use.
