Digital MEMS combustible gas sensor is using MEMS micro-fabrication hot plate on a Si substrate base, gas-sensitive materials used in the clean air with low conductivity metal oxide semiconductor material. When the sensor exposed to gas atmosphere, the conductivity is changing as the detected gas concentration in the air. The higher the concentration of the gas, the higher the conductivity. Use simple circuit can convert the change of conductivity of the gas concentration corresponding to the output signal. The sensor is high sensitivity, compact and precise. There are 2 pins are preset as alarm trigger signal output. It can be widely used in environmental safety, portable instruments and many other areas.
WPCH01 general type ceramic pressure transmitter has small size and light weight, it is convenient and easy to install. It adopts pressure sensor made by Winsen and it convert pressure into standard voltage signal output through a high reliable amplifying circuit and accurate temperature compensation circuit.
ZP06 adopts semiconductor sensor, which is designed for vehicle-mounted fuel gas leak alarm. It has the basic functions of vehicle-mounted flue gas leak alarm: electric power lamp, fault lamp, alarm lamp, output signal of working state; It can be installed respectively in the different positions of the vehicle, reducing the development period and guaranteeing high accurate detection.
Sensitive material of MQ-9B gas sensor is SnO2, which with lower conductivity in clean air. It detects carbon monoxide (1.5V) by method of cycle high and low temperature. At high temperature (5.0V), it can detect CO as well as clean the other gases adsorbed at low temperature. The sensor’s conductivity gets higher along with the CO and CH4 gas concentration rising. Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit.
ME2-CO-Ф14x14, fuel cell type sensor, detects gas concentration by measuring current based on the electrochemical principle, which utilizes the electrochemical oxidation process of target gas on the working electrode inside the electrolytic cell, the current produced in electrochemical reaction of the target gas are in direct proportion with its concentration while following Faraday law, then concentration of the gas could be get by measuring value of current.
Laser Dust sensor module is a common type, small size sensor, using laser scattering principle to detect the dust particles in air, with good consistency and stability. It is easy to use, with UART & PWM output; Small size is suitable for integrating.
Keeping low CO2 level is important for human health, which not only means that the current environment has sufficient fresh air, but also greatly reduce the risk of building syndrome. Winsen CO2 sensor meets RESET standard, which is widely used in control panels or thermostats for HVAC systems.
CO2 sensors plays an important role in health protection.It is widely used in indoor air quality(IAQ) monitoring like air quality monitor, air purifier, fresh air system, air conditioner and HVAC systems.Besides CO2 sensors,Winsen could also provides related products like TVOC,PM2.5(PM10),CO,ozone and formaldehyde sensor which meet RESET and WELL standards.
With the rapid development of the economy and the improvement of people's living standards, people have more and more attention to intelligent agriculture and livestock industry. Greenhouse planting has been quickly promoted and applied and it also manifests in smart granary, incubator, soil CO2 detection and other aspects.
