MQ307A CO GAS SENSOR
The MQ307A is a tin dioxide semiconductor gas sensor which has an excellent performance in CO detection. Using a mini-bead type sensing element with a periodic temperature change operation method, high sensitivity, selectively, small effect from humidity and other remarkable characteristics have been achieved. The MQ307A realizes the development of reliable CO detection devices.
Structure Gas sensitive semiconductor material is a mini bead type and a heater coil and electrode wire are embedded in the element. The sensing element is installed in the metal housing which uses double stainless steel mesh (100mesh) in the path of gas flow.
