IoT Based Air Pollution Monitoring System - IJSRD

PPM, we have used a library for MQ135 gas sensor and MQ6 is giving us value of 90 when there is no gas near it and the air quality safe level is 350 PPM and it should not exceed 1000 PPM. When it will exceed the limit of 1000 PPM, it will cause Headaches, sleepiness and stagnant, stuffy air. If it exceeds beyond 2000 PPM then it will cause increased heart rate and many different diseases. …

MQ135 CO2 PPM Calculation - Firmware - Particle

01/07/2016· I am working on MQ135 Gas sensor for CO2 PPM. I refer Internet blogs, datasheet, internet codes and i apply in my coding. I also got result in PPM in range of 420 to 450. is it true or not? What is CO2 PPM in Air? Also it gives me reading in loop, it can not go beyond 450 PPM. I used this equation Rs=( ( * RL ) - ( RL * Vout ) ) / Vout, where Vout is ADC value & RL=10 ratio=Rs/R0, where R0 = …

14/04/2020· If you need PPM of eCO2 (equivalent calculated carbon-dioxide) you better have a look at CCS811 air quality sensor. It is available as I2C sensor breakout boards so with male to female jumper wires you can physically attach it to any of the 3 slots of ANAVI Gas Detector (actually there are 4 I2C slots available on ANAVI Gas Detector, the 4th is dedicated for a mini OLED display). As of the …

Guide for MQ-2 Gas Sensor with Arduino | Random Nerd Tutorials

05/05/2016· The MQ-2 gas smoke sensor is an analog sensor. It outputs a voltage between 0 and 5V accordingly to the gas concentration in the atmosphere. The greater the gas concentration, the greater the output voltage. The lower the gas concentration, the lower the output voltage. When the Arduino reads analog values, it returns 1023 when it reads 5V, and ...

Measure CO2 with MQ-135 and Arduino Uno - Rob's blog

04/01/2017· 13 – 28 for CO2 ppm of about 500 – 2000 gives a resolution of about 100ppm/value measurement 32 – 61 gives about 52ppm/value 55 – 103 gives the best resolution of about 31ppm/value . These resolutions are valid if the scale is lineair, but the scale is logirithmic. So in the lower ppm part the resolution is much better, but above the 1000ppm the resolution will be very low. Wrong hardware. …
