6. Installation
The waterproof breathable film inside the product is waterproof but not waterproof against steam. Therefore, in order to prevent water
vapor from condensing inside the body, it should not be used in high humidity and steam environments.
6-1 Precautions for use of dust sensor
The sensor is made of water-resistant, dust-proof, and impact resistant materials. However, precision instruments need to be
carefully used and maintained to avoid impact and use in harsh environments such as corrosive liquids or gases.
The air inlet of the sensor shall not be blocked or polluted.
The electrolyte leakage will cause damage. Do not disassemble the sensor at will.
Do not use it when the shell is damaged or deformed.
The sensor shall avoid contact with organic solvents (including silicone rubber and other adhesives), coatings, agents, and fuel oils.
It is not recommended to use non-standard methods to test the sensor, and vertical air intake must be avoided. For example, put
the sensor directly on the concentrated ammonia, spray cigarettes towards the sensor, approach the sensor after the lighter is lit,
exhale towards the sensor, and close the sensor to alcohol. Because the regional concentration can be as high as tens of thousands
of ppm when liquid ammonia or alcohol volatilizes, and the carbon dioxide concentration in human breath can be as high as 40000
ppm, which will damage the sensor.
After being used for a long time in a high-concentration gas environment (it is prohibited to store and use it in a high-concentration
acid gas for a long time), it is slow to recover to the initial state.
When the sensor is stored, the working electrode and the reference electrode should be in a short circuit state.
The sensor is not allowed to be hot-plugged. The sensor must be plugged in after the power is turned off, otherwise, the sensor
may be damaged or abnormal phenomena may occur.
Please pay attention to whether there are requirements for limiting the use of wireless communication devices in this situation. If
there are such restrictions, please do not use this device. For example, during aircraft flight and landing, gas stations, gas stations
or other places with flammable and explosive materials.
6-2. Precautions for use of TVOC sensor
The installation place shall be far away from chemical corrosion environment.
The sensor and wire shall be far away from high-voltage electricity, heat source, etc.
The sensor belongs to precision instrument and should be stored in a dry, ventilated and normal temperature indoor environment.
The sensor is a precision device. Please do not disassemble it when using it to avoid product damage.
