Wholesale Air Quality Sensor HW180 

1.Product Description:
The inside of the HW180 sensor consists of a uniform precious metal oxide semiconductor formed by the heater and the outer surface. The outer part is encapsulated with a metal shell, and the bottom is led by four feet, which are the heating poles and the measuring poles. When the sensor encounters a detectable gas, the resistance of the sensor changes. The conductivity of the sensor increases accordingly with the increase of the detection gas concentration. Based on this conductive characteristic, a simple test circuit can be designed to convert this change in electrical conductivity into a signal output corresponding to a change in the gas concentration, thereby achieving gas detection.

Use caution:

1 Conditions that must be avoided
1.1 Exposure to silicone vapors
If the surface of the sensor absorbs silicone vapors, the sensor's sensitive material will be trapped, suppressing the sensor's
Sensitive and unrecoverable. Sensors should be protected from exposure to silicone adhesives, hair gel, silicone rubber, putty or
It contains where silicone additives may be present.
1.2 Highly corrosive environment
sensors exposed to high concentrations of corrosive gases (such as H2S, SOX, Cl2, HCl, etc.) not only cause corrosion or damage to the heating material and sensor leads, but also cause irreversible performance of sensitive materials change.
1.3 Alkali, alkali metal salts, halogen pollution
Sensors that are contaminated with alkaline metals, especially brines, and exposed to halogens, such as fluorine, can also cause performance deterioration.
1.4 Contact with water splashed in water or immersed in water can cause a decrease in sensitive properties.
1.5 Icing
The freezing of water on the surface of the sensitive element can cause the sensitive material to fragment and lose its sensitive properties.
1.6 The applied voltage is too high
If the voltage applied to the sensing element or heater is higher than the specified value, even if the sensor is not physically damaged or destroyed, the lead wire and/or heater may be damaged and the sensitivity characteristics of the sensor may be degraded.
