CO2 Gas Sensor Problems - Sensors - Arduino Forum

· I am also having a problem!! I recently bought a mg811 co2 gas sensor from sandbox electronics for a science fair project and have been having some problems with it. I burned it in for 2 days and allowed 2 hours for it to heat up but the readings either jump around, are very inaccurate or steadily climb! The calibrated it properly and have done everything this guide told me to do: Here is the ...

Why is hydrogen such a big issue for CO sensors? | GfG ...

The reason that CO sensors are potentially susceptible to hydrogen (H2) interference is the reaction that is used to detect gas. Hydrogen is actually part of the detection reaction. The relative response to hydrogen depends on the brand and model of sensor. Some commonly used CO sensors show a relative response to hydrogen as high as 60%. (Not GfG sensors, of course!) Sometimes the cross …

Can a Bad Sensor Prevent a Car From Starting ...

· This sensor lets the computer know the correct oil pressure is present. Since the efficient flow of engine oil is required to maintain proper lubrication, a failed sensor or one that is not able to relay data can trigger a fail safe mode in the ECU. If it sends a signal that the pressure is low, the computer may prevent the engine from starting.

Carbon monoxide detector - Wikipedia

The gas sensors in CO alarms have a limited and indeterminable life span, typically two to five years. The test button on a CO alarm only tests the battery and circuitry, not the sensor. CO alarms should be tested with an external source of calibrated test gas, as recommended by the latest version of NFPA 720. Alarms over five years old should be replaced but they should be checked on ...

4 Reasons Why Your Gas Gauge Isn't Working

· Gas Gauge Failure is less common, but still a possible issue. If the internal circuit is faulty, the gas gauge may only function in one section, such as between HALF and FULL or between EMPTY and HALF. If the internal circuits are shorted, they may peg to FULL or EMPTY. If the circuit is open, the gas gauge will likely sit at EMPTY and never move.

So I guess what im asking is since the O2 sensor is bad could this be the reason were having acceleration issues…other than that the car runs and drives fine . Christopher Bryant. I Have the same problem if you have found out any ...

The Problem with Portable Gas Detectors | Martek Marine

· Optical gas sensors provide an alternative over the conventional conductometric gas sensors. Carbon monoxide (CO) gas is generally regarded as one of the most dangerous air pollutants, hence, a room temperature operated CO gas sensor using ZnO sensing film deposited on Au coated prisms has been developed using an indigenously developed surface plasmon resonance (SPR) …

Carbon Monoxide Sensor Cross-Sensitivities Alcohols, VOCs ...

CO sensors can become saturated with target gas CO. If enough CO enters the sensor beyond maximum range (that listed in the instruction manual), the sensor is unlikely to be able to process all applied gas. When this scenario occurs, the electrolyte becomes saturated. A saturated sensor will continue to show high gas readings until the gas can be processed from the electrolyte. If saturation …

The challenges with electrochemical NO2 sensors in outdoor ...

· Interfering gases and cross-sensitivity. In a perfect world, an electrochemical sensor would only respond to the gas it is targeted to monitor. A nitrogen dioxide (NO 2) sensor would only detect NO 2 and a carbon monoxide (CO) sensor would only detect CO and so on. While electrochemical sensors are designed to be as specific as possible, most will respond in some manner to gasses other than ...

· Faulty exhaust gas temperature sensors can lead to unnecessary regenerations causing inconvenience for the driver. Lucas say that some sensors are harder to diagnose than others. PTC-type sensor failures are often misdiagnosed as DPF issues as after failure they continue to function sending incorrect signals to the ECU affecting the DPF regeneration process. NTC-type sensors are more …

Gas Sensor - an overview | ScienceDirect Topics

The drift can be related to the aging of the sensing film and may affect the gas sensor response. Moreover, a conductometric gas sensor can suffer from hysteresis and poisoning, due to too high values and/or too long time exposure to the GTc. Due to this complexity and to the large variety of application scenarios in which a gas sensor can be used, it is difficult to define a characterization technique that …

Cross sensitivity of toxic sensors: Chris investigates the ...

· Cross sensitivity is a sensor’s reac­tion to other gases which can “interfere” with how the sensor reacts. Exposing a sensor to a gas that is not the target gas can cause an undesirable effect; this may be a positive response, negative response or inhibition. Positive Response A positive response means that sensors respond to not just the target gas but to another gas as well. This ...
