The ppm reading of a CO sensor when measuring a gas with 1,000 ppm concentration under different temperature and pressure. 2. conditions. 3. Table 1 shows an example of the changes in the CO. 2 sensor reading (gas contains 1,000 ppm of CO at. 2. SATP) as temperature and pressure change, according to the ideal gas law.
Carbon monoxide, nitrogen dioxide, methane, etc. are a few gases that a gas sensor can detect. Comprehending the Architecture of a Gas Sensor. Though there are a variety of gas sensors availableBreathing is a complex process that relies heavily on the coordinated action of the muscles of respiration and the control center in the brain. The primary function of the lungs is to facilitate gas exchange between inspired air and the circulatory system. It helps bring oxygen to the blood and remove carbon dioxide from the body. Oxygen is critical for proper metabolism on a cellular level
What the sensor is actually measuring is the electrical resistance of this metal-oxide layer. This real time measurement and output of resistance is the first step in obtaining our TVOC reading. The change in resistance across the surface of the sensor is directly proportional to the change in concentration of the target gas (es).
