The sensor value only reflects the approximated trend of gas concentration in a permissible error range, it DOES NOT represents the exact gas concentration. The detection of certain components in the air usually requires a more precise and costly instrument, which can not be done with a single gas sensor. If your projects aims to obtain the gas concentration at a very precise level, then we do not recommend this gas sensor.

★★★★★ Great bag
Purchased this for my 23 year old daughter in the butterscotch color. Great versatile color. She loves the size -- perfect for day or going out at night. Chain can be double to shorten for nighttime and left long to wear as a crossbody during the day.
