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
