CO2 gas sensor and solenoid valve - Sensors - Arduino Forum

· Hi everyone, I am working on a project in my lab and need to create a system that will open a gas valve when the CO2 level is below a certain level, and to shut the valve when the CO2 rises above this level. So far I have gotten the arduino and vernier sensor interface shield to read the CO2 levels, but when adding a motor shield into the mix, the CO2 can no longer be read.

Analox AX60 CO2 Sensor Calibration & Reset Instructions ...

The O2 sensor in your vehicle monitors the exhaust gases coming out of the engine. It determines the amount of oxygen in the gases, which indicates how well the fuel is being burned. The O2 sensor then sends information to the electronic control unit, or ECU, the vehicle's computer. The ECU then adjusts the air-to-fuel ratio to optimize the fuel combustion. Sometimes an O2 sensor fails, and you need to replace it. Once you've replaced your vehicle's O2 sensor, you'll need to reset …

CO2 Sensor Calibration: What You Need to Know |

The most accurate method of CO2 sensor calibration is to expose it to a known gas (typically 100% nitrogen) in order to duplicate the conditions under which the sensor was originally calibrated at the factory. ISO certification is available on our high-end sensors to verify this process for medical, research or scientific purposes. Nitrogen calibration is also required if CO2 levels between 0 ...

TPMS SENSOR VALVE SERVICE AND REPLACEMENT

Sensor valves can be expensive to replace with single units costing anywhere from £45 to £150. Theoretically sensor valves should last for years, but due to wear and tear, corrosion or damage to the valve stem sleeve and nut, valve cap, valve core and rubber grommet which all help to ensure an air-tight seal, the sensor valve can become faulty or even fail prematurely. For these reasons ...
