The increasing level of air pollutants (e.g. particulates, noise and gases) within the atmosphere are impacting mental wellbeing. In this poster, we define the term 'TinyDigitalExposome' that takes us closer towards understanding the opportunity between environment and wellbeing using constrained microcontrollers. Specifically, we propose the opportunity of collecting particulate matter to infer mental wellbeing states whilst can have in the real-world
