Electrochemical Integrated Gas Sensor ZEHS04
Summary:
ZEHS04 is a diffusion type multi-in-one module, mounted with atmospheric monitoring module ZE12, to detect CO, SO2, NO2, and O3. It is also compatible to connect with dust sensor module, temperature and humidity sensor module externally.
With TTL or RS485 output, it is convenient to use and debug, which greatly shortens the user's design and development cycle, and meets customers' needs for different gas detection occasions.
Feature:
* High sensitivity, high resolution, long lifespan
* UART or RS485 output
* High stability, good anti-interference ability, excellent linear output
APPLICATION
Outdoor Air Quality Monitoring
Outdoor air quality monitoring is a process of measuring the concentration of pollutants in the atmospheric environment, observing and analyzing their changes and their impact on the environment. Air pollution monitoring is to measure the types and concentrations of pollutants in the atmosphere, and observe their spatial distribution and changing rules.
Air pollution is becoming more and more serious. The value of PM2.5 (referring to particulate matter with aerodynamic equivalent diameter less than or equal to 2.5 microns in ambient air) is a parameter index.
Industrial waste gas refers to the general term for various pollutant-containing gases discharged into the air generated during the fuel combustion and production process in the factory area of the enterprise. These gases enter the human body through the respiratory tract through different routes, some directly cause harm, and some have an accumulation effect, which will seriously endanger human health.
The septic tank is a device for processing feces and filtering. The principle is that the solidified material is decomposed at the bottom of the pool, and the hydrated objects in the upper layer enter the pipeline and flow away, preventing the pipeline from clogging and providing solidified objects (feces and other garbage)with enough time to hydrolyze.
