Installation precautions for dust monitors？

Choose a suitable installation location
The accuracy of dust monitors is closely related to the monitoring location, and it is very important to choose an appropriate location. The following points should usually be considered:
Keep away from pollution sources: The monitor should be away from direct dust sources (such as mechanical equipment, transportation roads, etc.), but also ensure that it can receive the actual concentration of dust in the air. If the equipment is installed too close to the dust source, the instrument measurement data may be high or locally interfered.
Avoid high temperature and humid environment: Avoid installing the monitor in places with high temperature, humidity or direct exposure to sunlight. Excessive temperature or humid environment may affect the measurement accuracy and service life of the instrument.
Ensure good ventilation: The monitor should be installed in a place with good ventilation conditions, avoiding areas with low wind speed or no wind. Changes in wind speed will directly affect the spread of dust, so when choosing an installation location, consider the impact of wind speed and wind direction on dust monitoring.
Appropriate height: The dust monitor should be installed at a certain height from the ground. Generally speaking, the instrument should be installed 1.5-2 meters above the ground to avoid being affected by dust or debris on the ground.

Power supply and connection
Power supply stability: Ensure that the power supply of the dust monitor is stable and the wiring is safe. Generally speaking, dust monitors require the power supply voltage to be within a certain range. If the voltage is too high or too low, it will affect the normal operation of the instrument.
Waterproof and dustproof: Since dust monitors are often used in outdoor environments, the power connection and the device housing must have a certain waterproof and dustproof ability to prevent rain and dust from entering the device and affecting its working performance.
Data transmission interface: Ensure that the monitor is connected to the data transmission system (such as wireless network, cellular communication, etc.) properly, and can accurately and real-time upload the monitoring data to the background system for analysis.

Instrument calibration and debugging
Calibration during initial installation: After the dust monitor is installed, necessary calibration must be performed to ensure the measurement accuracy of the instrument. Generally, a standard gas source or a known concentration of particulate matter is required to calibrate the device to ensure that it is consistent with the actual concentration.
Regular calibration and inspection: As the use time increases, the measurement accuracy of the instrument may decrease, so regular calibration and inspection are required. It is usually recommended to perform calibration and performance testing every 6 months.

Data storage and backup
Local data storage: ensure that the dust monitor can continue to operate and save monitoring data without network signals. Most devices are equipped with local storage functions to save data when communication is interrupted.
Data backup: To prevent data loss, the monitoring data of the device needs to be regularly backed up to the cloud or server, and a backup cycle should be set.
