MQ131 - Sensors - Arduino Forum

· The heater needs 6V, not 5V as in the example (the example is for an other sensor). So you really have to use 6V. These sensors are cheap and do fluctuate, so using 5V makes it even worse. Do you actually get a reading from the sensor, or did you use the wrong input and is your input floating ? The preheat time is 24 hours. Did you already had ...

What's best for measuring ozone, electrochemical sensors ...

· Electrochemical ozone sensors. In an electrochemical (EC) sensor, ozone gas diffuses across a porous membrane into a cell containing electrolyte and electrodes. When ozone comes into contact with the electrolyte, a change in electrochemical potential occurs between the electrodes causing electrons to flow. In zero air, little or no electron flow occurs. As the presence of ozone increases, the ...

How to Build an Ozone Water/Air Sterilizer Circuit ...

· Lowering the high voltage (below 2500°F) so that a cooler plasma is generated will produce ozone without the nasty nitrates. Setting up two parallel plates (one for the ground and one for the HV) and adjusting the HV until you see a dull blue glow between them (no arcing) will produce copious amounts of ozone without the nitrates being formed.
