A particulate matter (PM) sensor. The sensor comprises a mass separation fluid tunnel body defining a fluid inflow channel, a first fluid channel branch opening off of the inflow channel and having a first outlet, a second fluid channel branch opening off of the inflow channel and having a second outlet, and a fluid port between the first fluid channel branch and the second fluid channel branch, a fan located downstream of the first outlet and the second outlet, a photodetector located in the first fluid channel branch, and a computing device coupled to the photodetector having a processor and a memory storing instructions which, when executed by the processor, determines a mass concentration of particles in the first fluid channel branch based on an output of the photodetector.
