Hot-selling air quality detection module:ZEHS01

ZEHS01 air quality detection module

▲ ZEHS01 air quality detection module

Winsen established a special R&D team to develop a high-end module designed for air quality detection and very suitable for ventilation systems: ZEHS01. It is a integrated sensor module of the electrocochemical formaldehyde sensor (or VOC sensor), PM2.5 dust sensor, infrared CO2 sensor and temperature and humidity sensor. This product is small in shape and has the characteristics of good consistency, stability, accuracy, multi-detection intelligence. It is very convenient to integrate into the purifier and fresh fan, which can intelligently sense the change of air quality. In real time, PM2.5, carbon dioxide, formaldehyde (or VOC), temperature and humidity are displayed in real time.(Formaldehyde sensors can be replaced with VOC sensors based on customer needs)

ZEHS01 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.

Farewell to the traditional winding style—infrared temperature sensor applies to air conditioning

HVAC sensor

When using traditional air conditioners, we will find that the air conditioner's output and position are fixed. The position near the air outlet is easy to be blown and cause a headache, and the position of the air outlet will not feel the cool wind. The fixed way of air conditioning cannot actually meet people's needs.

The new intelligent air conditioner detects changes in human activity in different directions in the room through infrared temperature sensing technology. It automatically adjusts the temperature and air volume through the AI intelligent algorithm, ensuring the comfort of the human body while achieving energy conservation and environmental protection.

Winsen Technology's MRTD-3011 is a fully integrated digital thermopile sensor with a separate circuit I2C, using advanced MEMS technology, is currently one of the best-selling models in air conditioning applications.

In practical applications, one or several sensors can also be used to achieve a wider range of measurement according to the situation. This kind of intelligent air conditioner does not need to repeatedly adjust the temperature, and automatically enters the energy-saving mode after reaching the set ideal temperature. And it can be adjusted according to changes in body temperature during sleep to ensure sleep quality. At the same time, if you encounter a sudden drop in temperature, you don't have to worry about being "frozen awake" in the middle of the night.

Pressure sensor—maintaining the detection area, improving the efficiency of the air-conditioning system

In the central air conditioner, the controller and end sensor are key components that ensure the smooth operation and keep the system be energy-saving. The filter is used to filter the dust impurities in the ventilation pipeline. The pressure sensor at the indoor ventilation port is used to monitor the pressure difference at both ends of the filter at the outlet. More dust on the filter is accumulated over time, which gradually affect the air circulation. When the air circulation is not smooth, the air pressure difference at both ends of the filter is increasing. When the pressure sensor feels changes in pressure, the upper machine receives a signal from the pressure sensor. When the signal value reaches the alarm point, the alarm will start to remind the cleaning staff to clean or replace the filter. In addition, the pressure sensor also participates in the controlling of the air supply offer.

Fresh air is needed to be flowing to ensure the comfort and health of indoor personnel, the air flow changes according to the function of the building and the number of residents. Sensors are often used to measure air flow and pressure to improve the efficiency of the air conditioning system. Among them, pressure sensors can ensure that a large amount of air is drawn back into the building, and through the evaluation and monitoring of air pressure, quality and ventilation, the breathing of indoor personnel can be guaranteed.

Why Does the Sensitivity of the Semiconductor Sensor Reduce During Use?

There are five main reasons: 1) Organosilicon, sulfide, phosphide, chlorine (fluorine) compound, alkali metal, etc. will poison the sensor; 2) The power supply voltage of the sensor has changed; 3) The sensor has been used for too long (Exceeded service life); 4) The test gas concentration is too high; 5) The sensor is subjected to severe vibration or destructive external conditions.

Can the Catalytic Sensor Be Made into a Digital Display?

MC series catalytic products have good linearity and can be made into digital display products.

All the Mc Series Products Measure Combustible Gas, What is the Difference?

MC series products are different in power supply voltage and current, their appearance and structure are also different; in addition, they are divided into two types: domestic and industrial. Industrial products require explosion-proof and the shell should be the explosion-proof structure of metallurgical powder mesh. The MC100 series is mainly used for domestic use, and the MC110 series is mainly used for industry.
