SDS011 air quality sensor~
This feature is included only in tasmota-sensors.bin

Nova PM Sensor SDS011 can measure the air quality very accurately by measuring air particles or dust based on laser detection.
Specifications:
- Voltage: 4.7 - 5.3V DC (5V DC with <20mV ripple advised)
- Power consumption: 70mA ±10mA (in operation), <4mA (laser and fan sleep mode)
- Measuring range: 0.0-999.9 μg/m3
- PM2.5 and PM10 output
See manufacturer site for more information.
