Gas-sensitive controller circuit

Published:2011/3/29 22:26:00 Author:Jessie | Keyword: Gas-sensitive controller

Gas-sensitive controller circuit
This paper uses gas sensitive components and TWH8751 to compose gas-sensitive controller, it can be widely used in coal mine, chemical industry, metallurgy and family, etc. When RQ touch combustible gas, theresistance drops, when the gas concentrations reach a certainlevel, 8751will connect andmake relay work, R1 is work current to limit RQ, which can lengthen the service life of RQ components. W is the sensitivity controllor, according to some gas concentrations, it adjusts to a certain value, make the decline of RQ, TWH8751 connected and work, achieve purpose of control. (View)

Pyroelectric infrared switch circuit diagram
When infrared sensor processing special chip HX9228receives infrared sensor's output signal, after completing linear amplification, two-way amplitude discrimination, signal processing, delay timing, blockade timing, its pin 2 outputs high-level make triode 8050 conduction, drive relay K suck closes. Then the relay contacts control corresponding controlled object. In the diagram, R2 adjustes choiceaccording to environmental brightness, when thepin 9 is low potential, chip can't trigger. (View)
