UCB-PATS
UCB-PATS uses the sensing chamber from a commercial home smoke detector that depends on natural air flow and diffusion to bring particles in a sensing chamber.

PATS+
PATS+ is the next generation PATS. It is smaller than the UCB-PATS and performs more on-board processing via a multicore Propeller microcontroller. It uses a modified version of the commercially available Sharp GP2Y1014 sensor.

Dylos Air Quality Monitor
A benchtop monitor that relies on a sophisticated, but still consumer-based optical particle counter, the Dylos Air Quality Monitor. A controlled air flow brings particles through a laser beam where pulses of scattered light are transduced into electrial pulses.

Wireless SUMS
A wireless Stove-Use Monitoring Systems (SUMS). The wSUMS sends compressed data wirelessly, allowing data to be downloaded unobtrusively without entering a household.

Time-Activity Monitors (TAMs)
An ultrasound-based system for monitoring the amount of time spent by different household members in specific household locations and in vicinity of important sources of air pollution.
More Info




Air Exchange Rate Monitors (ARMs)
This system consists of a data-logger with between one and four non-dispersive infared (NDIR) carbon dioxide sensors.
