MG811 High Sensitivity Carbon Dioxide Detection Sensor Module Analog+TTL 2-Channel Output CO2 Detector

Features:
- Support signal output indication.
- Dual signal output (analog output and TTL level output).
- TTL outputs a valid signal at a low level. (The signal light is on when the output is low, it can be directly connected to a microcontroller.)
- Analog output 0-2V.
- Has high sensitivity and good selectivity towards carbon dioxide.

Specification:
- Working voltage: DC6V
- Module size: 32 x 20mm
- Net weight: about 10g

Package Included:
- 1 x MG811 CO2 Sensor Module (with Probe)

Precaution:
- It is recommended to preheat for at least 5-10 minutes before testing for the first power on use.
- Please avoid vibration and falling, and strictly prohibit liquid from flowing into the interior of the sensor.
- Do not apply this module to systems involving personal safety.
- Do not place this module in high concentration organic gas for a long time.
- Do not install the module for use in environments with strong air convection.
- The testing module has a delay and requires more than 10 seconds for output.
