Arduino Archives - CreateLabz

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 ...

GitHub - ostaquet/Arduino-MQ131-driver: Arduino driver for ...

02/05/2012· Using parts primarily from Adafruit Industries, I made an environmental sensor. Temperature, humidity, light level, and ozone concentration data were collected using the DHT22 sensor, a photo cell, and Futurlec’s MQ131 gas sensor. A Boarduino and Xbee got our sensors talking to our school server and a 6V solar panel powered the beast.

SD card produces corrupt files - Storage - Arduino Forum

11/07/2021· Hello all, I have already read about similar problems in various threads, but unfortunately I can't pinpoint the problem with my setup. As you can see i the pictures the sketch works fine at the beginning, all good. But after some time it will eventually turn into completely corrupted files, even the existing ones, which are then become unreadable. My setup: Arduino MEGA Data-Logger shield ...
