The utility model relates to sensor technical field discloses a kind of three-in-one
laser environment monitoring sensors, including shell,
humidity detection module, particulate matter detection module are installed on shell, shell includes: upper shell group;Frame, frame includes frame body, shunt is provided on frame body,
airway baffle,
airway baffle and lower shell cooperate to form main air duct, secondary air duct;Lower shell group.The utility model is designed by main, secondary air duct, optimizes
airflow path, to ensure that
airflow high-efficiency flows through
heating element, to realize active heat dissipation;Different shapes annular groove structure design is used, effectively blocks the heat conduction path on PCB board, reduces the influence of heat
diffusion;Different shapes groove baffle structure design is used, reduce the influence of heat
radiation to temperature and
humidity module, improve equipment stability;Active heat dissipation, heat conduction block and heat
radiation protection three dimensions are respectively proposed innovative solution.
