=====================
Carbon monoxide, CO for short. It is a colorless and extremely toxic gas without taste or smell, which is formed as a result of combustion due to a lack of oxygen. Without overloading you with detailed information, I will tell you the most important thing: the normal concentration of carbon monoxide at home is less than (10 ppm). A concentration higher than (520 ppm) for two hours causes headaches, dizziness, nausea, and a concentration of (1000 ppm) leads to loss of consciousness. At a CO concentration in the air of (1500 ppm), a fatal outcome is possible.

Добрий день! То який висновок, гідний датчик, чи то датчик руху з генератором випадкових значень? Дякую!
