I have this sensor MQ131 by sainsmart: https: ... For example if you have 100ppm CL2 and 200ppm O3, you'll read 300ppm on your arduino. If you want a sensor which will give you the ppm of only one gas, it will cost you much much more. – Vincent Teyssier Aug 14 '16 at 15:55.

30/09/2020· MQ131 Ozone sensor measurement. unluz September 30, 2020, 11:57am #1. Hi there! I recently bought Arduino Uno Compatible I2C Shield + MQ131 Ozone Gas Sensor. Despite the fact that I produce ozone gas from the generator, I can’t measure proper values at all. The sensor reads ppm when there is no ozone produced and goes down dramatically ...
The MQ131 ozone gas sensor makes it easy to monitor ozone concentration levels using our I2C Mini Module form factor. The MQ131 is connected to an ADC121C 12-Bit Analog to Digital converter, which is capable expanding to 9 gas sensors per I2C port using just two address jumpers (making full use of the floating address system).

13/06/2021· You can connect Arduino and [MQ-131] sensor and practice the sensor easily with simple coding. In this section, we investigated the influence of ozone on the human body, the reference concentration, the measurement range of the simple measuring instruments, and the sensors used in the measuring instruments, We also measured ozone directly using the MQ131 ozone gas sensor and Arduino…
06/05/2021· 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 ...
Arduino library for ozone gas sensor MQ131. This is a comprehensive Arduino library to obtain ozone (O3) concentration in the air with the Winsen MQ131 sensor. The library supports both versions of the sensor (low concentration and high concentration), the calibration, the control of the heater, the environmental adjustments (temperature and humidity) and the output of values in ppm (parts per ...

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 …

07/05/2016· I didn't have to use any capacitors to improve range, they are directly connected to some medium-quality Arduino Nano GND/ One of them is a lighting controller node, ~3 meters from the PA/LNA gateway (+ a 30cm wall) on the same level as the gateway. The other one is a repeter node and is ~10 meters from the gateway (+ a 20cm wall, same level as the gateway). In this case, radio ...
