There are two main types of gas monitoring in air pollution control. The traditional industrial chain records gas data through sensors, collects the data through manual scanning and completes the monitoring.

The gas monitoring industry chain based on the Internet of Things monitors through sensors, uses Bluetooth NB-loT, Zigbee, GPRS and other means to transmit information, and finally collects, records and analyzes data through big data and cloud computing software platforms. Regardless the type of the industrial chain, gas sensors are necessary. Sensor technology enables people to easily collect accurate data in various situations, and quickly make decisions and take counter measures. Among them, PM2.5, PM10, SO2, NO2, CO, O3 and other gas environment monitoring sensors are widely used in atmospheric environment monitoring.

ME4-03-E4 PPB level Ozone Sensor

Target Gas: O3 Ozone

ME4-O3-E4 Ozone gas sensor is constant potential electrolysis type. Oxidation-reduction reaction with ozone gas and oxygen take place respectively on the working electrode and on the counter electrode. The process releases electric charge and generates current. The current is in direct proportion to the concentration of chlorine gas and conform to faraday's law. So the concentration of the target gas could be got by measuring the value of current. The 4th electrode (auxiliary electrode) is used to compensate the zero current, to make it has the characteristics of strong signal level and low zero current.
