Title:
MULTI-PARAMETER SENSING MODULE
Document Type and Number:
WIPO Patent Application WO/2016/078217
Kind Code:
A1
Abstract:
A multi-parameter sensing module (10). The multi-parameter sensing module (10) comprises: a shell (101), a plurality of partition plates (102, 103), a fan (113), a particulate matter sensor (107), a gas sensor module (110, 111), a temperature sensor (112), a temperature and humidity sensor (106), a heating device (108) and a control unit (109). The heating device (108) heats air to be at an effective working temperature before the air enters the gas sensor module (110, 111); the control unit (109) compensates a detection value of the particulate matter sensor (107) according to air humidity and controls the heating device (108) to be opened and closed, so that, the multi-parameter sensing module (10) can work normally under a low temperature environment, the sensor failure can be prevented, and moisture condensation inside the multi-parameter sensing module (10) can be avoided. The plurality of partition plates (102, 103) and the shell (101) are integrally formed by a totally-enclosed casting aluminum structure, so that the gas-tightness and shielding capacity of the inside of the module are guaranteed, and meanwhile, it is guaranteed that laser leakage is avoided, and anti-jamming capability is improved.
