1. 01

   The whole GaugeRead AI

   A battery camera wakes on a timer, photographs analog gauges under IR flash, reads each needle on the device and sends the numbers.

2. 02Brain

   ESP32-S3-WROOM-1

   The brain: it runs the gaugeeye-vision program

3. 

   03

   OV5640 camera

   Photographs the gauge face with a set-once focus

   ESP32-S3-WROOM-1 · DVP 8-bit camera bus · UXGA frames

4. 

   04

   IR flash LEDs (x2)

   Light the dial for each photo, day or night

   ESP32-S3-WROOM-1 · GPIO 14 to LED sinks · Flash pulse, 0.5 A each

5. 

   05

   RAK3172 supervisor and radio

   Wakes the camera, checks limits and sends the reading

   RAK3172 (STM32WLE5) · UART with a READY line · Dial readings, CRC16

6. 

   06

   Two D lithium cells

   Run the camera for years between visits

   ESP32-S3-WROOM-1 · 3.6 V leads (JST-PH) · Battery power

How the parts connect

GaugeRead 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 GaugeRead AI

void app_main(void) {
    load_calibration();                       // dials, ellipses, min/max marks
    camera_on(); set_focus(stored_vcm_code);
    for (int f = 0; f < 3; f++) {
        if (ae_needs_flash()) flash_on_vsync();      // GPIO 14, 25 ms
        fb[f] = esp_camera_fb_get();
        extract_dial_rois(fb[f], roi[f]);     // Y plane only
    }
    camera_off();
    for (int d = 0; d < n_dials; d++)
        result[d] = read_needle(roi, d);      // register, unwrap, line fit, median of 3
    uart_send_crc16(result, n_dials);         // then raise READY
}

Today they pay for a cellular alarm dialer (Mission M110 $1,195 plus service, about $55 per station per month in a Florida utility filing), drive the round to read gauges and pay for a yearly heat survey.

2. 27 Oct 2026, 09:15Small towns, water districts and private owners (HOAs, RV parks, mobile-home parks) have three jobs at every pump station: answer the alarm, know each pump is still pumping, and catch a hot connection in the panel. Daily lift-station checklists list alarms, levels and pump readings (MaintainX), pressure is read with pumps off and running (Indiana DNR), a site visit costs $500–2,000 or more (Vista Projects), and a cellular dialer alone is $1,200–1,600 (Mission, Sensaphone). Our own three products for it cost $2,827 and $87 a month per station.
