How does an Oxygen Sensor Work? -

The mechanism of the laser oxygen sensor was created to design analyzers for real-time measurement of gases such as H20, H2S, CO2, NH3, and C2H2 in gas streams. Many sensors have been used in various applications such as combustion systems, power plants, coal, and waste incinerators.

Carbon dioxide - Wikipedia

Carbon dioxide (chemical formula CO 2) is an acidic colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas. The current concentration is about % (412 ppm) by volume, having risen from pre-industrial levels of 280 ppm. Natural …

Carbon monoxide detector - Wikipedia

A carbon monoxide detector or CO detector is a device that detects the presence of the carbon monoxide (CO) gas to prevent carbon monoxide poisoning. In the late 1990s Underwriters Laboratories changed the definition of a single station CO detector with a sound device to carbon monoxide (CO) alarm.

CO2_Sensor_SKU_SEN0159-DFRobot

This is the first CO2 sensor on the opensource hardware market. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is designed to set the threshold of voltage. Once the CO2 concentration is high enough (voltage is lower than threshold), a digital signal (ON/OFF) will be released.

Oxygen sensor - Wikipedia

An oxygen sensor (or lambda sensor, where lambda refers to air–fuel equivalence ratio, usually denoted by λ) is an electronic device that measures the proportion of oxygen (O 2) in the gas or liquid being analysed.. It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Dr. Günter Bauman. The original sensing element is made with a thimble-shaped zirconia ceramic …

Application Note 313: CO2 sensor - Design concept for solar-powered CO2 ...

The concentration of carbon dioxide (CO 2) in a room is an indicator for indoor air quality (IAQ). CO 2 sensors are therefore used to measure indoor air quality in a building to perform demand-based ventilation. Sensors for this purpose operate in the range between 500 and 5000 ppm (ppm = parts per million, 10000 ppm = 1%). The figure below shows a typical CO 2 concentration in an office …
