Smart Parcel Locker Notification Solution
Budget: ₹600 – ₹1,500 INR
**Project Title: Smart Parcel Locker Notification System using EC20 (4G LTE)**
I need a complete hardware and firmware solution for a **Smart Parcel Locker Notification System** designed for offices, hostels, or apartment buildings.
The system should detect when a parcel is placed inside a locker and **immediately send an SMS notification** to the assigned user using the **Quectel EC20 LTE module**. The solution should be low-cost, compact, and reliable for real-world deployment.
**Requirements:**
Features:
* Detect parcel placement using a **weight sensor** or **IR proximity sensor**.
* Send an **SMS notification** to a pre-defined mobile number using **EC20 LTE** module.
* Optional: Store timestamp of delivery to SD card or internal memory.
* Simple user interface with **status LED** (power, message sent).
* Operates on **DC adapter or Li-ion battery** with charging circuit.
* Must be **modular** to allow scaling up to multiple lockers in the future.
Deliverables:
1. **Schematics and PCB design** (preferably in **KiCad**).
2. **Bill of Materials (BOM)** with manufacturer part numbers.
3. Fully functional **firmware code** (C/C++ or Arduino-based) to:
* Interface EC20 via UART (AT commands)
* Detect sensor triggers
* Send SMS via EC20
4. Guidance for hardware assembly and testing.
5. Optional: Basic enclosure design or mechanical layout.
# Bonus (Optional):
* OTP verification via SMS to open locker
* HTTP or MQTT support to log deliveries online
* OLED screen for locker status
