0-2V analog voltage outp CO2 concentration detection sensor module MG811

Description

1. CO2 acquisition signal amplification processing;
2. Add temperature compensation function to achieve full temperature range detection, more accurate;
3, CO2 detection sensitivity is higher, warm-up response can be faster in 2-5 minutes;
4, increase the power work indicator, output TTL signal indicator
5. The probe can be plugged and unplugged for easy testing. This module has added the signal amplification function, which can be directly connected to the microcontroller development board.

Features
1, with signal output instructions;
2. Dual signal output (analog output and TTL level output);
3. The TTL output effective signal is low. (The signal light is on when the output is low, and can be directly connected to the microcontroller)
4, analog output (0 ~ 2V / 0-4V) voltage output is optional, the default is 0-2V;
5. High sensitivity and good selectivity to carbon dioxide;
6, has a long service life and reliable stability;
7, fast response recovery characteristics;
8. The probe can be plugged and unplugged for easy testing.

application
Carbon dioxide detection device for home and environment. Suitable for the detection of carbon dioxide
concentration, the test concentration range of carbon dioxide gas sensor: 0 to 10000ppm
