Sensor in the Gas Detector Industry
Winsen mainly provides professional sensors for CO2 detectors, formaldehyde detectors and refrigerant leak detectors
MH-Z Series CO2 Sensor, our Star Product
Most people spend about 90% of their time indoors. Carbon dioxide is an important indicator to measure the freshness of indoor air. Human breathing will cause the indoor CO2 concentration to rise continuously and the oxygen content to decrease, making people drowsy. Winsen uses the infrared gas CO2 sensor in the CO2 detector. The MH-Z14B and MH-Z19C series are our star products, and the annual sales of 800,000 pcs are enough to prove their reliability and popularity. We generally use CO2 detectors to detect the indoor CO2 concentration to remind people or automatic equipment to ventilate, so as to ensure that we are breathing fresh air.
Excellent Self-calibration Function
The sensor has its own STM32 microcontroller whose firmware intelligently controls automatic calibration. After the module works for a period of time, it can intelligently judge the zero point and automatically perform zero point calibration. The calibration cycle is every 24 hours since the module was powered up. The zero point is 400ppm. This method is suitable for office and home environments, not suitable for agricultural greenhouses, farms, refrigerators, etc.

Winsen always adhere "independent innovation, sustainable development" in the process of high-speed development, fundamentally improve the technical level of the domestic gas detection industry, and promote the development of related industries.

The application of ammonia sensors in different industries
Many people may not know much about ammonia, but they must have smelled it. There are ammonia existence in unclean toilets, crowded people etc. As a "useful" and "toxic" gas, ammonia gas exists in all walks of life, and sensors used to measure ammonia gas are also widely used in different industries.
The application of PM2.5 sensors in different industries
Fine particles are also called PM2.5. Fine particles refer to particles with a diameter of air dynamic equivalent in the ambient air less than or equal to 2.5 microns. It can be suspended in the air for a long time. The higher the concentration in the air, the more severe the air pollution is. The impact of PM2.5 on the atmospheric environment and human health is also greater, which is the main murderer who leads to black lungs and haze days.
The application of MEMS sensors in different industries
MEMS sensor is a cutting -edge research field developed on the basis of microelectronics technology. After more than forty years, it has become one of the major scientific and technological fields of the world. It involves a variety of disciplines and technologies such as electronics, machinery, materials, physics, chemistry, biology, medicine, etc., and has broad application prospects.
The application of infrared gas sensors in different industries
Compared with other types of gas sensors, infrared gas sensors have a lot of advantages, such as good selectivity, long life, no dependence of oxygen, small interference by the environment, not easy to poison, high accuracy, etc. With the development of sensing technology, more and more advanced infrared gas sensors have appeared on the market.
