Module Features

size: 35mm X40mm X28mm L * W * H
main components: ammonia gas sensor
the working voltage: DC 5V

Characteristics

the module with level signal output, with alarm signal indicators;
the sensor module with analog signal output voltage range :0-5V;
active low level signal outputs can be driven PNP transistors can also be connected microcontroller IO port;
the analog output voltage increases with the concentration, the higher the concentration the higher the voltage;
to ammonia, trimethylamine, ethanolamine gas with high sensitivity;
with a long service life and reliable stability;
after preheating with fast response and recovery characteristics;
with mounting holes to facilitate fixed installation;
the probe can plug design, easy to test;
the module with temperature compensation function, adaptability and more reliable.
