06/05/2021· Hello people! I started to use Arduino for a few months in college and I like it so much I wanted to buy one for myself and after some time I discovered the MQ-135 sensor but I want to know exactly the level of PPM of NH3,NOx, alcohol, Benzene, smoke,CO2 like when is it present in the air and how much based on that PPM because I want to make a graphic evolution of NH3,NOx, alcohol, …
28/09/2020· MQ-135 Smoke Gas Sensor Module Features. MQ series sensor uses a small heater inside with an electrochemical sensor in order to measure different kinds of gas combinations. The MQ-135 sensor is a sensor for detecting air quality. This sensor is able to detect smoke, CO2…

Interfacing of MQ135 Gas Sensor with Arduino: In today’s world, we encounter different scenario where we see different gasses being emitted in atmosphere such as home appliances like air conditioner and industrial chimneys. Monitoring of these gasses is very important with safety point of view. Gas Sensors are very helpful in accomplishing this task.
01/02/2021· Testing the connection of MQ-135 Gas Sensor with Arduino: Now it's time to test the project. To test the circuit, we have to upload Arduino code using Arduino IDE. I will attach an Arduino scratch. Upload the program open serial monitor. You will get the results in the serial monitor. The MQ-135 Gas Sensor Arduino Code:

17/11/2020· Code to Measure CO2 Using Arduino MQ135 Sensor. The complete code for interfacing MQ-135 Sensor with Arduino is given at the end of the document. Here we are explaining some important parts of the MQ135 Arduino code. The code uses the Adafruit_GFX, and Adafruit_SSD1306, and libraries. These libraries can be downloaded from the Library Manager in the Arduino IDE and install it from there. For that, open the Arduino …
06/05/2020· MQ135 Sensors are usable as an air quality sensor for detecting a wide range of gases, including NH3, NOx, alcohol, benzene, smoke and CO2. For me, these sensors should be affordable by the price but also deliver acceptable measurements. That’s the reason I decided to test this MQ135 Sensor. Five of them are available in our region even with amazon for 11€ which make these little …

27/05/2021· CO2 Concentration with MQ135 Sensor and Arduino – In this article, we will find the concentration of Carbon Dioxide using the MQ135 sensor and display it on the OLED I2C display module. So basically we will be making the Carbon Dioxide Parts per Million Meter. Atmospheric CO2 …
04/01/2017· MQ135 not suitable for CO2. I think that I will stop my attempts for using the MQ-135 as a CO2 meter. With 1 sensor I measured different voltages on the analog port with same amount of CO2. It probably is to responsive to other gases in my surroundings. (Airport and highway).
MQ135 + Arduino+16x2LCD+ESP8266+ThinkSpeak. Hi All, I have just bought a MQ135 . I started arduino basics with LED blinking , interfacing and then started with my real project. e I have seen in the data sheet of MQ135 that it can measure Ammonia, Sulfide,CO2 and Benze steam. It can also be used to detect smoke and alert.
16/07/2018· How to make a CO2 ppm meter with MQ135 sensor and Arduino NANO. This topic has been deleted. Only users with topic management privileges can see it. Sandim_Kaushik last edited by . I know some people might think this question is silly because I google it immediately but I have referred to MANNNNYYY blogs and videos but ALL of the comments were negative and now I dont know WHAT …
26/04/2015· I´m using the MQ135 sensor for measuring CO2 gas in an arduino board and while using the code above we have some questions. 1.-The return value for GetRZero function is 270 kOhm for us, and you got 41 KOhm, is it possible? or is it just wrong? With this obtained value our PPM is around 20, should we change the parameters? 2.- Once we heated ...
05/07/2020· Download the MQ135 Library and include it in your Arduino IDE. Prepare the hardware setup with MQ-135 gas sensor and 10KΩ Load Resistor (RL) After the 24 hours preheat process, perform the following procedures in the environment of 20 degree C/35% air temperature, and read the value of RZERO. #include "".
