RFID · UPI QR · Coin Payment
Smart automated water dispensing machines with real-time IoT monitoring, multi-mode digital payment support, and a centralised cloud dashboard for full remote control.
A complete IoT solution — from hardware payment acceptance to cloud-based remote control.
Pre-loaded RFID cards let users tap and dispense water instantly. Balances update in real-time on the central server.
Dynamic QR codes enable instant UPI payments. Supports GPay, PhonePe, Paytm and all BHIM-UPI apps.
616-series multi-coin acceptor handles ₹1, ₹2, ₹5 and ₹10 coins with automatic denomination detection.
Live machine status, transaction feed, and sensor data streamed to the admin dashboard over GSM/WiFi.
Sensors report tank fill percentage continuously. Automated SMS alerts fire when levels drop below threshold.
Dual-core 240 MHz ESP32 handles all payment logic, sensor reading, OLED output, and secure server comms.
Transactions queue locally on the ESP32 during outages and sync automatically to MySQL on reconnection.
GSM module sends SMS notifications for low tanks, machine faults, power failures, and revenue milestones.
Enable, disable, reboot or reconfigure machines remotely. No physical access required for changes.
Five seamless steps from payment to dispensed water — fully automated, real-time verified.
Monitor every machine, track revenue, manage RFID wallets, and send remote commands — all from one web-based interface.
Industrial-grade components for reliability, low power consumption, and field replaceability.
