1. 01

   The whole VapeSense AI

   A ceiling disc measures room air, classifies each event as vape, smoke or steam and reports it by radio, with no camera or microphone.

2. 02Brain

   ESP32-C6-MINI-1

   The brain: it runs the vapesense firmware program

3. 03

   SEN66 air module

   Measures fine particles, VOC, NOx, CO₂, humidity once a second

   ESP32-C6-MINI-1 · I²C (6-pin cable) · 1 Hz air readings

4. 04

   BME690 gas sensor

   Scans gas resistance to tell sprays from smoke

   ESP32-C6-MINI-1 · I²C (shared bus) · Gas resistance profile

5. 

   05

   RAK3172 LoRa radio

   Sends event summaries to the building gateway

How the parts connect

VapeSense AI, wired up

Every part, what links it to the brain, and how the data reaches your phone. A solid line is a cable; a dashed line is a radio link.

The program

What controls VapeSense AI

for (;;) {
    sen66_read(&air);                    // I2C 400 kHz, 1 Hz
    features_push(&win, &air, &gas);     // baseline-subtracted
    if (ev.state == QUIET && air.pm1 > baseline.pm1 + 25)
        event_start(&ev);                // QUIET -> EVENT
    if (ev.state == EVENT) {
        event_record(&ev, &air);
        if (decayed_to(&ev, 0.20f) || ev.secs > 900) {
            ev.cls = gbt_predict(event_features(&ev), &ev.conf);  // <= 200 trees
            uplink_event(&ev);           // LoRa or MQTT
            ev.state = QUIET;

A smoked room costs about $620 to $1,300 to put right (Minut), and vape detectors sell for about $1,500 each (CDW).

2. 27 Oct 2026, 11:15A small hotel, motel or rental host has three room problems sold separately: smoking in non-smoking rooms ($620–1,300 an incident, Minut), ACs cooling empty rooms (occupancy setback worth up to about $180 a room a year, vendor-reported by Onity, and a BPA study found guests and housekeeping undo plain sensors), and damp bathrooms in humid places where in-room ACs dry poorly (mould repairs $500–10,000+ a room, Hospitality Net). Our own three products for it cost about $547 and $13.50 a month a room.
