Review on π¬ Seeed Studio HCHO Sensor - Grove (Semiconductor VOC Gas Based WSP2110) by Nick Palacio
Works perfectly, functions are very limited
Works perfectly but gives no quantitative results, only three conditions: free air, low pollution, high pollution. It's not clear what this means in practice, so it can only be used to monitor changes in air quality and not actual conditions. The problem isn't with the Grove board per se, but with the sensor they used to detect it - it has very limited capabilities.
- Definitely bad product
