mq131 beginner Sensors Arduino Forum

20210506· The MQ131 requires 100k (50k to 500k) as load resistor. The other sensors use lower values. I have not tested a MQ131 myself, therefor I don''t know how it behaves. I''m not sure if I have the sensor somewhere. 2 days preheat is okay. Perhaps the resistor value (the "load resistor") is too low. If it drops down to fast to zero, increase the ...

Carbon Monoxide Gas Sensor MQ7 Arduino Project Hub

I had previously published a project with an MQ sensor and received a lot of critical feedback on it. Today I also expect your feedback, but only of a positive nature: with the MQ7 carbon monoxide gas sensor and the matching PCB from Pololu, analog measurement using the ADC from the Arduino is no longer a problem. I followed the recommendation to use a 10KOhm resistor and soldered the MQ7 to ...

MQ131 sensor question. Sensors Arduino Forum

20210506· I am conducting a study to detect whether or not emissions come out of an electric vehicle using the Arduino and a gas sensor. I have the MQ131 gas sensor connected, as well as an LCD to output the values when not connected to a laptop. The MQ131 should be detecting NOx, CL2 and O3, according to the datasheet. I have left the sensor on for several hours trying to burn it in, but not the ...

Arduino: Reading PPM values from MQ131 Ozone sensor ...

1. First you need t make it burn for 24hrs mini (48 advised). Just plug it and wait. Then for calibration you need a reference atmosphere free of NOx, CL2 and O3. In this reference atmosphere you should get an output value of 0. I don''t know this model you bought exactly, but most of these gas sensors mounted on a PCB have a mini eeprom so the ...

20210506· Using Arduino. General Electronics. bestanamnetnogonsin April 4, 2017, 12:00pm 1. Hi. I want to use a gas sensor like this one. It states the heater needs 5V. As I am running it on a battery pack (maybe 3 or 4 times V?), i wonder, how exact does the voltage have to be? Will it still work while the battery packs voltage starts to drain? What exactly happens if I exceed or go beneath the ...
