Configure and read out the Raspberry Pi gas sensor (MQ-X) S ensors are necessary to detect the components of the air. These are used in smoke detectors. However, instructions for using these gas sensors at the Raspberry Pi are rare, which is why in this tutorial the general use of such MQ modules at the Raspberry Pi is shown.
· ADC121C_MQ131. ADC121C_MQ131 Ozone Gas Sensor. The ADC121C_MQ131 Gas sensor makes it easy to monitor ozone concentration levels using our I²C Mini Module form factor.
· Wie man jegliche MQ Sensoren (MQ135 usw.) konfiguriert und ausließt wird am Beispiel des Arduino & Raspberry Pi Gas Sensor MQ-2 in diesem Tutorial gezeigt.
· Hi, There is two ways of using the MQ131: - directly the sensor itself (bare / naked sensor) - via a module I used to have a module and I remove the sensor from the module because the documentation doesn’t exist. The two important things are: 1. You have to preheat the sensor for 48h at 5V to have consistent result. 2. In order to compute the ppm/ppb, you have to calculate the Rs/R0 and ...
Sensor MQ131 requires minimum 48h preheat time before giving consistent results (also called "burn-in" time) There are two different MQ131; a black bakelite sensor for low concentration of ozone and a metal sensor for high concentration of ozone. This driver is made to control the "naked" Winsen MQ131.
· The MQ131 ozone gas sensor is capable of sensing ozone air concentration levels between 10ppb and 2ppm. The ideal sensing condition for the MQ131 is 20°C ±2°C at 65% ±5% humidity. This Device is available from [SKU: ADC121C_MQ131_I2CS]

· It has its own fixed reference voltage, so changes in supply voltage (the MQ131 is ratiometric) will result in changes in your readings. Readings of 200-800 means you are at the very low end of the range, measuring very low voltages. That by nature is difficult, you can improve the reading by increasing the ADS1115's gain, but you also have to look at theMQ131 itself: how stable can you …
· For the MQ131, the first parameter is for the heater which is already integrated into the module so you can assign it to any pin that’s not already used. The ozone gas sensor we are using is the black bakelite low concentration version so we indicate it on the third parameter. The 10000 is the load resistance. Lastly, we initialize the variable buf to store incoming messages. void setup() 1 ...

Go to my GitHub for: - Some small hardware changes improve the design, including the ability to turn off itself from software, remediating one of the biggest drawbacks of the design - how to handle low battery. - A PCB v2 design is now published together with a guide to easily apply the change to boards - CAD files for complete enclosure
According to the picture, the sensor is a Winsen MQ131 low concentration (black bakelite version). You can have additional information on the sensor in the datasheet.. Your sensor is mounted on a PCB with some features like converting values (analog to digital), controlling the heater, maybe providing I2C bus...
· 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 MQ-131 gas sensor connected, as well as an LCD to output the values when not connected to a laptop. The MQ-131 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 ...
