Part of the Mobile Air Quality Sensing system (MAQS), M-Pods consist of various sensors, a low-power microprocessor, and a Bluetooth interface. The M-Pods house carbon dioxide, carbon monoxide, total VOC, ozone, nitrogen dioxide, light, temperature, and humidity sensors. An Atmega 168 microcontroller logs the data and manages the system. The sensors are placed on the circuit board to receive even airflow and a fan pulls air through the device to minimize sensing latency.
The M-Pod can communicate via its Bluetooth interface with smartphone applications.
