Very easy to use (with Tasmota), fast response (seconds) and very sensitive. Spray some sanitizer/deodorant a few rooms down, or light up some toast, and it's in the "red zone" in about 30 seconds. Open the window and the reading will return to a safe value just as quickly. I used Wemos D1 Mini Lite and this sensor; That's it, just two parts and a USB power supply, cable and case. Added readings to another project with a display and also alerted our phones when air quality crossed a threshold.
