Capacitive sensing Wikipedia

In electrical engineering, capacitive sensing (sometimes capacitance sensing) is a technology, based on capacitive coupling, that can detect and measure anything that is conductive or has a dielectric different from air. Many types of sensors use capacitive sensing, including sensors to detect and measure proximity, pressure, position and displacement, force, humidity, fluid level, and ...

Operating principle ‐Electrochemicaltype gas sensor

The oxidation potential of CO gas (as expressed in Equation 1) is lower than the oxidation potential of the electrode(2H+ + 2e⇔ H 2), oxidation of CO has less noble potential than deoxidization. Since this reaction occurs easily, no external energy is needed to stimulate the sensor’s chemical reaction, unlike with threeelectrode type sensors. As a result, this twoelectrode type ...

How does an NDIR CO2 Sensor Work? |

These sensors solved the size problem by using folded optics and metalized molded plastic to reflect the light through a curved shape (referred to as a ''waveguide'') that was longer than the footprint of the sensor module. The highly reflective coating ensured that the CO2 molecules inside the gas sample chamber would absorb the same amount of light as traditional straightpath design.

Carbon Dioxide (CO HVAC Basics Honeywell

Carbon monoxide (CO) can be harmful, even at very low levels (25 to 50 ppm). CO2 as an IAQ Indicator Claims that CO2 sensors are indoor air quality (IAQ) sensors are inaccurate. CO2 levels are one piece of the undefined indoor air quality equation. Low CO2 levels do not indicate good air quality while high CO2 levels do not mean that air is ...
