Arduino Smoke Level Detector using MQ135 Sensor with Alarm
20200513· The MQ135 smoke sensor consists of a tin dioxide (SnO2), a perspective layer inside aluminum oxide microtubes (measuring electrodes) and a heating element inside a tubular casing. The end face of the sensor is enclosed by a stainless steel net and the backside holds the connection terminals. Smoke is emitted from the source by burning anything. With the smoke cascade on the tin …
Which means " burnit" the sensor (MQ135)? Sensors ...
20210506· The sensor MQ 135 works with many gases, I get the concentration of CO2. No you don’t. You get whatever gas the MQ135 is reacting to. It could be CO2 but it could also be any of the other gasses or the sum of several gasses. If you calibrate your sensor with CO2 then you calculated a value as if it were all CO2. Don’t expect these sensor to be very accurate. Out of the box these sensor ...
