Demand on CEMS (Chemical Emission Monitoring Systems) is going to jump along with the commitment of the Indonesian government on the recent COP26. We predict that incoming policies will require industries and other pollution-emitting sectors to control their chemical emission. One feature to assist this requirement is CEMS. Faraday wants to explore the opportunity in this industry, therefore a prototyping step is necessary. Dexter monitors chemical emissions from industrial air, using sensors & networks built on the existing infrastructure of Faraday.
