What is the NO2 Gas Sensor and how does it work? The EC Sense ES1-NO2-2000 Nitrogen Dioxide Gas Sensor is a cutting-edge solid polymer electrochemical gas sensor, known for its extended lifespan and durability. Notably, it operates without any power consumption and boasts a compact design. This ES1-NO2-2000 Gas Sensor is specifically engineered to detect Nitrogen Dioxide gases, which are crucial to detect in various applications. When paired with the EC Sense Smart Digital Board, it simplifies integration, eliminating the need for labor-intensive sensor calibration. Understanding the technology behind it Solid polymer electrochemical technology represents a groundbreaking advancement in electrochemical detection. It relies on the principle of electrochemical catalytic reactions. In essence, these sensors respond to target gases by producing a minute electric current signal, typically proportionate to the gas concentration. Traditional electrochemical sensors use liquid or gel electrolytes, which pose operational challenges. EC Sense's solid polymer electrochemical sensors effectively overcome these obstacles. The inner workings of the technology EC Sense's solid polymer sensors incorporate a composition of three electrodes in contact with the electrolyte. Each electrode consists of a large surface area of precious metals and other materials. These electrodes, the electrolyte, and the surrounding air interact as the gas diffuses through the back of the porous membrane into the sensor's working electrode. At this stage, the gas is oxidized or reduced. This electrochemical reaction initiates an electric current to flow through the external circuit.
