Outdoor Sensor-Activated Water ATM

Descripción de la oferta
I need a complete concept-to-deployment package for a rugged, outdoor Water ATM that dispenses purified water hands-free through a sensor-based outlet. The unit must accept cash as well as online payments: coins or notes through a secure validator plus instant wallet/card options integrated via QR or NFC. The system will be installed entirely outdoors, so weather-proof cabinetry, sunlight-readable status indicators and tamper resistance are essential. Hygiene is equally important; the sensor should trigger flow without users touching any surface, and the plumbing must support periodic auto-flushing and easy filter replacement. Core expectations • Mechanical drawings and enclosure design suitable for manufacturing • Electronics schematics, PCB layout and firmware that handle the sensor trigger, flow metering, cash validator and online payment module • Cloud or on-device reporting so daily volume and revenue can be viewed remotely • Assembly guide plus bill of materials with off-the-shelf components available locally Acceptance criteria 1. Prototype dispenses accurately to ±2 % for 250 ml and 1 L selections. 2. Cash and online transactions post to the log within 30 seconds. 3. System passes a 48-hour outdoor stress test (rain, 45 °C heat). 4. Complete documentation delivered in editable CAD, Gerber and source code files. If you have prior experience building vending or kiosk systems that marry hardware, embedded code and payment gateways, this project should feel familiar. I’m ready to move quickly once the design direction is locked.
