This mount is designed to attach an ESP32-CAM microcontroller to a water meter Aquabasic PMK-basic 25. Together with the open source firmware "AI-on-the-edge" (https://github.com/jomjol/AI-on-the-edge-device) of the user Jomjol it can read the water meter automatically and send the current counter status to a server via MQTT.
