Review on π¬ Seeed Studio HCHO Sensor - Grove (Semiconductor VOC Gas Based WSP2110) by David Epps
The documentation says it lasts 48 hours but a fairly constant reading of less than 24 hours
Just got this yesterday and after a few hours of running it has stabilized somewhat. Documentation says it lasts 48 hours but a fairly constant reading in less than 24. Very sensitive as I'm a smoker and picks up cigarette smoke in my room. Tested by simply breathing on it and also recognizes it very well. Butane light is easy to see even at 6 inches. The sensor recovers in less than 2 minutes. So far I'm happy with its performance and the code can be found on the Grove and Adafruit website. Please google as Amazon does not allow website links in comments or reviews. .
