CO2 Sensor MG811 Carbon Dioxide Sensor Gas Detection Sensor Module Voltage Type

Demo Board Type:ARM
MG811 Carbon Dioxide Sensor:CO2 Sensor

MG811 Carbon Dioxide Sensor CO2 Sensor Gas Detection Sensor Module Voltage Type
Product parameter:
Size: 32mm X22mm X30mm
The main chip: LM393, carbon dioxide gas sensing probe
Working voltage: DC 6V
Product features:
With signal output indication;
Dual signal output (analog output and TTL level output);
The TTL output valid signal is low. (when the output is low, the signal is bright and can be connected to the microcontroller directly)
Analog output (0~2V/0-4V) voltage output optional, the default 0-2V;
It has high sensitivity and good selectivity to carbon dioxide;
With long service life and reliable stability;
Fast response recovery feature;
The probe can be inserted and designed to facilitate testing.
Upgrade add function:
CO2 acquisition signal amplification, ranging from 0-2V and 0-4V optional;
Increase the temperature compensation function, realize the full temperature range detection, more accurate;
Replace the ceramic base with better thermal resistance, better heat transfer and heat conduction;
CO2 test sensitivity higher, faster response to preheat, in 2-5 minutes;
Increase the power work indicator, output TTL signal light.
Application:
Carbon dioxide detection device for home and environment. Suitable for carbon dioxide concentration detection, carbon dioxide gas sensor testing range of concentration: 0 to 10000ppm
