1. 01

   The whole StoveSentry AI

   A bar under the range hood watches burner heat and whether anyone is near. Pans left alone sound an alarm, then alert staff by phone.

2. 02Brain

   ESP32-S3 sensor bar

   The brain: it runs the stovesentry firmware program

3. 03

   MLX90640 thermal array

   Reads burner temperatures on a 32×24 grid at 4 Hz

   ESP32-S3 sensor bar · I²C (1 MHz) · Thermal frames

4. 04

   LD2410C presence radar

   Senses a still person standing near the stove

   ESP32-S3 sensor bar · UART + one GPIO pin · Presence and distance

5. 05

   BME688 gas sensor

   Adds a burnt-food hint; it never alarms alone

   ESP32-S3 sensor bar · I²C (shared bus) · Gas index, temperature

6. 

   06

   "I'm here" button

   Clears the alarm and restarts the away timer

   ESP32-S3 sensor bar · 6-wire cable, one pin · Button press

7. 07

   Piezo sounder

   Gives the local alarm at 85 dB before anyone is called

   ESP32-S3 sensor bar · 6-wire cable, one pin · Buzz on or off

8. 08

   USB-C and 4×AA backup

   Powers both units; the cells cover a power cut for 8 hours

   ESP32-S3 sensor bar · 5 V on the cable · 5 V power

   7 key parts, one program, and your phone

How the parts connect

StoveSentry 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 StoveSentry AI

for (;;) {
    mlx90640_get_frame(&frame);                 // I2C 1 MHz, 32 x 24
    bool present = ld2410_present() || gpio_get_level(LD2410_OUT);

    for (int z = 0; z < n_zones; z++)
        zone_update(&zone[z], &frame);          // max, p90, deg C per min

    kitchen_step(&k, zone, n_zones, present, button_pressed());
    if (k.state == LOCAL_ALARM) buzzer_on();    // works with Wi-Fi down
    if (k.changed) mqtt_publish_event(&k);      // QoS 1, TLS
    if (minute_tick()) mqtt_publish_state(&k);
    vTaskDelay(pdMS_TO_TICKS(250));
