Battery-Powered LoRa ESP32 Parking Tracker

I need a working prototype that lets me monitor a single-car residential parking spot without running any wiring. The concept is simple: • Hardware: a custom ESP32 board that combines LoRa radio, BLE, and a low-power magnetic (Hall-effect) sensor... (Budget: ₹1500 - ₹12500 INR, Jobs: Arduino, Electronics, Firmware Development, LoRa, Microcontroller, MQTT, PCB Layout, REST API)
