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 1*MG811 Carbon Dioxide Sensor
