Carbon dioxide sensor module CO2 sensor module MG811 module Output voltage 0-2V
At the request of our customers, we have upgraded this sensor:
1. CO2 acquisition signal amplification processing;
2. Increase the temperature compensation function to achieve full temperature range detection, which is more accurate;
3, CO2 detection sensitivity is higher, the preheating response is faster in 2-5 minutes;
4, increase the power work indicator, output TTL signal indicator
5, the probe can be plugged and unplugged to facilitate testing.
This module has been added signal amplification function, and can be directly connected with the MCU development board. Our agent 炜 的 MG811, absolutely authentic, reasonable price.
Features
First, size: 32mm X22mm X30mm length * width * height
Second, the main chip: LM393, carbon dioxide gas sensor probe
Third, the working voltage: DC 6V
Fourth, the characteristics:
1, with a signal output indication;
2, dual signal output (analog output and TTL level output);
3. The TTL output valid signal is low. (When the output is low, the signal light is on, it 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 to facilitate testing.
Fifth, the application:
Carbon dioxide detection device for home and environment. Suitable for the detection of carbon dioxide concentration, carbon dioxide gas sensor test concentration range: 0 to 10000ppm
