Application Principles Indication for module’s status Preheating status: Power indicator is shining once power on and it gets light for long in three minutes after preheating is finished Fault status: When the sensor malfunctions, yellow indicator enters the cycle of light on for 750ms and off for 750ms. Alarm status: When the gas concentration reaches the threshold, re d indicator enters the cycle of light on for 70ms and off for 130ms. Application Development of household ozone alarm device and household ozone detector.

1.1 Exposed to organic silicon steam
Module will lose sensitivity and never recover if it absorbs organic silicon steam. Module must avoid exposing to silicon bond, fixature, silicon latex, putty or plastic contain silicon environment.
1.2 High Corrosive gas
If the sensors are exposed to high concentration corrosive gas (such as H2S, SOX, Cl2, HCl etc.), it will not only result in corrosion of sensors structure, also it cause sincere sensitivity attenuation.
1.3 Touch water
Sensitivity of the sensors will be reduced when spattered or dipped in water.
1.4 Freezing
Do avoid icing on sensor’s surface, otherwise sensing material will be broken and lost sensitivity. 2 .Following conditions must be avoided
2.1 Water Condensation
Indoor conditions, slight water condensation will influence sensors’ performance lightly. However, if water condensation on sensing material surface and keep a certain period, sensors’ sensitive will decrease.
2.2 Used in target gas with high concentration
No matter the sensor is electrified or not, if it is placed in high gas concentration for long time, sensors characteristic will be affected. If lighter gas sprays the sensor, it will cause extremely damage.
2.3 Long time storage
The sensors resistance will drift reversibly if the module is stored for long time without electrify, this drift is related with storage conditions. Modules should be stor ed in airproof bag without volatile silicon compound. For the modules with long time storage but no electrify, they need long galvanical aging time for stability before using. The suggested aging time as follow: Table3. Storage Time Proposed aging time Less than one month No less than 48 hours 1 ~ 6 months No less than 72 hours More than six months No less than 168 hours

2.4 Long time exposing in adverse environment
No matter the modules electrified or not, if exposed to adverse environment for long time, such as high humidity, high temperature, or high pollution etc., it will influence the module’s performance badly. 3. If there are conformal coating around the environment, please be sure th e coating gets dry totally before using the module. 4. Before resetting the alarm value, please contact our technical support team.
