Interfacing MQ137 Sensor with Arduino to Measure Ammonia ...

Feb 09, 2018· Turns out that MQ137 sensor can measure NH3, C2H6O and even CO. But, here I am interested only in the values of NH3. However you can use the same method to calculate ppm for any sensor you like. This graph is the only source for us to find the value of ppm and if we could somehow calculate the ration of Rs/Ro (X-axis) we can use this graph to ...

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.

How to Trick a Motion Sensor to Stay On or Off? - LampHQ

How does the bypass work? The circuit is relatively simple. In principle, a simple light switch has two contacts which interrupt the current flow in the off state and pass it through in the on output of a motion detector is also a simple switch with the same functionality. If both switches are now connected in parallel, the closed switch will always override the open switch.
