7 Symptoms of a Broken MAP Sensor

· In modern engines, the engine control module (ECM) measures or calculates air flow via either a mass air flow (MAF) or manifold absolute pressure (MAP) sensor. Turbocharged engines may use both, but naturally-aspirated engines typically use one or the other. If the MAP sensor is failing or broken, the ECM — and thus, the engine — can't function properly. By maintaining and repairing your ...

NOx Sensors - DieselNet

Abstract: Automotive NOx sensors are primarily of the amperometric type, with two or three electrochemical cells in adjacent first cell electrochemically pumps O 2 out of the sample so it does not interfere with the NOx measurement in the second cell. Commercial sensors, available from several suppliers, are used for the control of NOx adsorber and SCR aftertreatment.

Vaillant CO-Sensor VC 356/2-E - HaustechnikDialog

meine 2,5 Jahre alte VC 356/2-E war jetzt schon zweimal in Folge morgens kalt mit Fehler 55 / CO-Sensor. Beim ersten mal half Aus/An. Beim zweiten mal hatte ich die Entstörtaste gedrückt und der Brenner lief auch wieder an. Habe dann allerdings trotzdem nochmal ausgeschaltet, weil nach Betätigen des Entstörknopfes die Regelung offenbar nicht erkannt wird. Jedenfalls lief er dann nicht mehr

PIR sensor always HIGH - Sensors - Arduino Forum

· The problem is I always have the input pin on HIGH. I tried adjusting the sensitivity but with no luck. I attached a picture of my setup. The weird thing is, I think somehow the sensor works without the + and GND pins plugged in (just the output pin). Sometimes it behaves weird, but most of the times it detects my palm. 2014-05-31 _ 4128×3096 568 KB. 2014-05-31 _ ...

CO2 Sensor Calibration: What You Need to Know |

To solve the problem of CO2 sensor calibration for IAQ, Senseair in Sweden developed Automatic Baseline Calibration (ABC). The theory behind ABC calibration is that for IAQ use, at some point each day a room is unoccupied, and the CO2 level should return to 400 ppm, the same as outdoor air. By storing the lowest CO2 readings taken over time (typically several days) in the EPROM memory, an ...

Adafruit SCD-30 - NDIR CO2 Temperature and Humidity Sensor

· The SCD-30 is an NDIR sensor, which is a 'true' CO2 sensor, that will tell you the CO2 PPM (parts-per-million) composition of ambient air. Unlike the SGP30, this sensor isn't approximating it from VOC gas concentration - it really is measuring the CO2 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific ...
