Module Features

One, size: 35mm X40mm X28mm L * W * H
Two main components: sulfur dioxide gas sensor
Third, the working voltage: DC 5V
IV characteristics
               1, the module with level signal output, with alarm signal indicators;
               2, the sensor module with analog signal output voltage range :0-5V;
               3, active low level signal outputs can be driven PNP transistors can also be connected microcontroller IO port;
               4, the analog output voltage increases with the concentration, the higher the concentration the higher the voltage;
               5, the sulfur dioxide gas with high sensitivity;
               6, with a long service life and reliable stability;
               7, after preheating with fast response and recovery characteristics;
