## Questions & Answers

**Q: Is there detailed documentation available for how to interface this with Arduino?**
A: Yes it is available

**Q: How many of these can I connect to a single Arduino?**
A: Hi, just ensure the working voltage and circuit, you may connect six of these to a single arduino, each analog interface for 1 piece. please note it uses 5v and the maximum current is 20mA.

**Q: Can this sensor detect a specific thing that changes the air quality? like if the sensor were to suddenly have cigarette/vape/juul smoke blow onto it?**
A: Yes

**Q: El producto contiene algún certificado de calidad de medición?**
A: no, si lo tuviera, no costaría lo que cuesta, es más una referencia; estoy viendo que certificar las medidas obtenidas
