What is the difference between a multifunctional air quality sensor and a liquid crystal gas sensor?
Gas sensor is an important branch of sensor technology, which can monitor the composition and concentration of gas, and convert this information into data that can be directly used by people, instruments or computers. At present, gas sensors are widely used in gas monitoring places such as building HVAC, building energy conservation, smart homes, schools, hospitals, and airport stations. Multifunctional air quality sensors and liquid crystal gas sensors are representative of gas sensors and are widely used in urban environmental monitoring. What are the similarities and differences between these two devices? Let's get to know it together. Multifunctional air quality sensorMultifunctional air quality sensor (RS-MG111-N01-1) is an air environment multi-element sensor, using electrochemical and catalytic combustion sensor principles, can be used to detect air The temperature, humidity, PM2.5, PM10, atmospheric pressure, light, TVOC, CO2, formaldehyde, O3, CO, CH4, O2, SO2, NO2, H2, H2S, NH3 and other elements in the environment basically cover the reflection Various indicators of air quality. Liquid crystal gas sensor110 Liquid crystal gas detector (RS-*-*-N01-C) is an ambient gas concentration sensor that uses the principle of electrochemical sensors to monitor hydrogen, Carbon monoxide, hydrogen sulfide, methane, nitrogen dioxide, sulfur dioxide, oxygen, formaldehyde, ozone, phosphine and other gases have the characteristics of rapid response and strong anti-interference ability. After a unique compensation algorithm, multi-stage standard gas calibration, there is Long life, high precision, high repeatability and high stability, and with high-quality large-screen LCD, the value can be directly viewed on site. 1. Function comparisonDue to the structure of the equipment, there are differences in the number of gas elements that the two products can monitor:Multifunctional air quality sensorMultifunctional air quality sensor can simultaneously Eleven environmental elements can be monitored, and at most eight elements can be selected from ten environmental elements such as temperature, humidity, PM2.5, PM10, atmospheric pressure, light, TVOC, CO2, formaldehyde, O3, etc., and can be matched with CO, CH4, O2 , SO2, NO2, H2, H2S, and NH3 are monitored. Liquid crystal gas sensorOne device can only choose to monitor one gas, which can be selected from hydrogen, carbon monoxide, hydrogen sulfide, methane, nitrogen dioxide, sulfur dioxide, oxygen, formaldehyde, ozone, and phosphorus. Choose one of the hydrogen and other gases for monitoring. If you need to monitor multiple gases, you can also choose multiple devices to monitor. 2. Comparison of appearance and installation methodsMulti-function gas sensor The multi-function gas sensor is a circular device with a diameter of 168mm; the device and the base are connected by a snap. Depending on the mounting position of the base, it can be wall-mounted or ceiling-mounted; the probes are built-in probes except for TVOC, which use extension probes. Liquid crystal gas sensorThe liquid crystal gas sensor adopts the standard 110*110mm size, with a large-screen LCD display intuitive; the liquid crystal gas sensor adopts a wall-mounted shell design, which can be installed on the wall or cabinet according to the needs, and Equipped with infrared remote control, with remote configuration parameters, quick switch alarm and other functions. 3. Comparison of output signal methodsMultifunctional gas sensor (RS-485, WIFI) Wired: RS-485 digital signal output can be selected. Wireless: If you want to use wireless upload, you can switch to wireless upload through the 485 line connected to the concentrator/small host, or directly select WIFI type equipment. LCD gas sensor (analog, RS-485) Wired: LCD gas sensor can choose analog and RS-485 output. Wireless: Same as the multi-function gas sensor, the device will be connected to the concentrator/small host to upload wirelessly. In the future, gas sensors will develop towards miniaturization, high integration and intelligence, to achieve more accurate detection and faster response.
The global market was valued at environmental monitoring systems in OEM sensor and is expected to reach a market value of environmental monitoring systems by OEM sensor, with a CAGR of environmental monitoring systems during the forecast period.
