MQ-135 Air Quality Smog Sensor Arduino
The sensor detects concentration of benzene, alcohols and smoke in the air.
Results can be obtained by measuring the voltage on the analog output. The system should be supplied with voltage from 2.5 V to 5 V.
Thanks to built-in voltage converter, it is possible to use with 5V logic devices.
- Supply voltage: 2.5V-5V
- Outputs: analog, digital
- Working temperature: -10 C - 45 C
- 3mm Mounting holes
- Dimensions: 31mm x 20mm x H 22mm
