MQ-131 Ozone Gas Detection Sensor Module
Product Name: MQ131 Ozone Gas Detection Sensor Module (with analog and TTL level signal output)
First, size: 32mm X 22mm X 30mm length * width * height
Second, the main chip: high concentration / low concentration MQ131 gas sensing probe
Third, the working voltage: DC 5V
Fourth, the characteristics:
1. It has a signal output indicator indication;
2, dual signal output (analog output and TTL level output);
3. The TTL output valid signal is low level; (when the output low level, the signal light is on, it can be connected to the IO port of the single chip)
4. The analog output decreases with increasing concentration, and the higher the concentration, the lower the voltage;
5. High sensitivity to ozone gas (detection concentration range: low concentration probe 10PPB-1000PPB; high concentration probe 10ppm-1000ppm)
6, has a long service life and reliable stability;
7, fast response recovery characteristics;
8, with mounting holes, convenient for fixed installation;
9, the probe can be plugged and unplugged for easy testing.
