Review on πŸ”¬ Seeed Studio HCHO Sensor - Grove (Semiconductor VOC Gas Based WSP2110) by Julian Davidson

Revainrating 4 out of 5

All in all, it's a pretty good sensor, but it's picking up speed because it needs something.

doesn't give you a PM2 reading. This gives you the exact zero to 1000 value you would find in airborne hazard reports. Overall, this is a pretty good sensor, but it does track speed as it takes time to heat up, making the device's accuracy questionable.

Cons
