The value of a professional scent machine comes less from its ability to release scent than from releasing it at the right time and at the right intensity. The mechanism that makes this possible is the weekly program and the work/pause cycle on the control board. In this article we cover these two layers and the role of the real-time clock (RTC). Two-layer scheduling logic A well-designed scent board solves scheduling in two independent layers: ...

The most critical power component of a scent machine is the pump: it is the actuator that atomizes the fragrance oil or pushes it into the HVAC duct. The job of the control board is to switch this pump safely and reliably from the 220–240 V AC mains. In this article we cover relay selection, the power supply, the difference between resistive and inductive loads, and mains safety. Onboard AC-DC: why you don’t want an external adapter Control boards run on low-voltage DC (typically 5 V / 3.3 V), but the pump is at mains voltage. There are two approaches: ...

A scent machine control board is the electronic board that forms the brain of professional scent (aroma) machines. Its job, in one sentence: to manage mains power, run the pump at the right times and durations, and carry all of this out automatically according to a weekly program. In this article we cover what the board is, what components it consists of, and how it works, in a technical but accessible way. ...
