Why measure CO2 in HVAC applications? |

When enough people enter a room, the CO2 level rises because of the CO2 from their exhaled breath, and the HVAC system begins to bring in the fresh air. When the people leave, the CO2 level drops because they are no longer breathing in the room, and the fresh air dampers close. Because most common uses for carbon dioxide in HVAC applications ...

Really Homemade Oximeter Sensor - Arduino Project Hub

First, understand how heartbeat sensor works. I've started this project playing with a KY-039 heartbeat sensor that I've found in a kit sensor that many of us have in home. As you can see in the circuit below, it's just a infrared led that lights a photodiode. There are also two resistors to protect the led and read the small signal of the sensor.

Gas Sensor - an overview | ScienceDirect Topics

Resistive gas sensors are based upon monitoring a change in the electrical conductivity of a sensing material (primarily, non-stoichiometric semiconducting metal oxides like SnO 2, WO 3, ZnO and TiO 2) at high temperature (typically, 200–500 °C) in the presence of the gas. They are perhaps the earliest form of available gas sensor on the market. For example, Taguchi gas sensors …

How Does a Gas Sensor Work? - Gas Monitors

01/05/2015· LEL sensors, like the toxic sensors, can realistically last for quite a while and have been known to last for over four years. However, they are the most sensitive sensors in a four-gas monitor, and can break if the monitor is dropped. Highly fuel-rich but oxygen-deficient atmospheres can also lead to LEL sensor failure due to build-up of tar and unburned fuel on the activated ring.
