- size:32mm x 22mm x 30mm length * width * height.main chip:lm393 carbon dioxide gas sensor probe.working voltage:dc 6v.1 with a signal output indication;2 dual signal output (analog output and ttl level output);3 ttl output signal is low.
- (when the output low signal lamp,can be directly connected to the microcontroller 4),analog output 30~50mv voltage,the higher the concentration of higher voltage;
- 5 the carbon dioxide has very high sensitivity and good selectivity;6 has long service life and reliable stability;
- 7 fast response and recovery characteristics 8 the probe can be inserted;design,convenient test.
- carbon dioxide detection device for household and environment.suitable for the detection of carbon dioxide concentration,carbon dioxide gas sensitive components test concentration range:0 10000ppm to
this is a carbon dioxide sensor.
