SMART LPG GAUGE Modular external electronic accessory for residential stationary LPG tanks 1. PROJECT OBJECTIVE Design a professional, compact and modular electronic accessory that can be installed externally over the analog level indicator of a residential stationary LPG tank. The device will measure the angular position of the original gauge mechanism using an AS5600 magnetic rotary position sensor and communicate with an ESP32-C3 SuperMini. The accessory must preserve the original analog gauge visibility and must not require opening, drilling, modifying or mechanically interfering with the original gauge or the LPG tank. The design must be suitable for FDM 3D printing. 2. REFERENCE GAUGE Use the Mexican residential LPG indicator IUSA CIN TQ1, product code 311894, as the initial mechanical reference. Reference specifications: Nominal visible dial diameter: approximately 40 mm. Gauge type: analog magnetic level indicator. Application: residential stationary LPG tanks. Manufacturer: IUSA. Product reference: CIN TQ1 / 311894. IMPORTANT: The 40 mm measurement is a commercial reference, not a verified complete mechanical drawing. Do not assume the external body diameter, mounting depth, clamp geometry or internal shaft dimensions. Create adjustable parameters for all unverified dimensions. The design must support interchangeable mechanical adapters for other residential LPG gauge manufacturers. 3. MAIN CIRCULAR STRUCTURE Create a circular mounting frame surrounding the original indicator. Initial design parameters: Nominal visible dial diameter: 40 mm. Initial internal frame diameter: 42 mm. Nominal wall thickness: 2.5 mm. Adjustable internal diameter. Rounded external edges. Reinforced structural areas. Requirements: Preserve at least 85% of the original gauge viewing area. Keep all numbers, markings and the original needle visible. Never use a solid front plate. Avoid reflections and unnecessary obstructions. Keep the frame compact and lightweight. Include a removable front or rear service component if required.
