Hi, you mention the I2C bus in the article but you’ve used the SPI bus in the Python code. Why ? Is the SPI bus is better than the I2C. Which one to prefer ? Reply; Joey 852020 at 14:42. Hi, I don´t know where to find the MCP3008 library. Can you help me please? Reply; Julien 852020 at 18:37. Hi, I have the ads1115 ADC instead of the MCP3008. I want to connect it two analog devices. Is ...

The software is modular and you can easily add/remove processes and screens so you can add sensors or make it light on power by removing some, if you wish. The only limitation is the number of GPIO pins. However, sensors can be easily added if I2C, or alternatively an I2C expander could be …
20190219· Question about Ozone Gas Sensor 12Bit (MQ131 i2c) Bhaskar February 20, 2019, 3:43am 2. Hi, can you display the raw adc value and see how the values react when there is a change in Ozone level. Thanks. February 25, 2019, 2:38am 3. Hi There, Just chiming in here as I think I have the same problem (sensor reads ppm when there is no ozone present and goes down when there is …
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...
20210505· daveinnj: you need to do the math. each module has a data sheet. each data sheet lists power consumption. here is a start. MQ135 = Heating consumption less than 800mw mq131 = Heating consumption Less than 1100mw so2 = Working current: 150mA
The I2CAS1 is a +5V I2C Expansion Shield for the Arduino platform. This shield acts as a gateway to the entire NCD I2C product line, allowing limitless expansion possibilities. This shield could be the single most significant shield for your Arduino ever made simply because of it’s extreme low cost and broad expansion possibilities. Integrated pullup […]

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 ...
