I prefer Chinese clone of Arduino Nano for its outstanding price of 3, but any 8bit arduino will work here. Sketch uses some advanced timers operation, and was tested only on atmega328 microcontroller although probably it will work well on others too. 1. MQ7 CO sensor. Most commonly available with this Flying Fish sensor module, it has to run through a small modification, details in the ...
