Automated Drug Locker Dispenser Variant 29 Kit with ESP32 + Servo
3-Factor Secure Automated Drug Locker Dispenser Kit — ESP32, Fingerprint, RFID & PIN
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Control access to sensitive medications with a real-world embedded system that enforces fingerprint, RFID, and PIN verification in sequence. This advanced kit guides you in building a fully functional automated drug locker dispenser, complete with timestamped access logs and a servo-driven release mechanism — ideal for clinical, institutional, or research environments where audit trails are non-negotiable.
What You'll Build
You will construct a wall-mountable, enclosed dispenser that opens a secure compartment only after a registered fingerprint, a valid RFID card/tag, and a correct 4-digit PIN are presented. The 0.96-inch OLED walks users through each step, the DS3231 RTC stamps every event, and the microSD module stores a permanent log. Two SG90 servos actuate the door and a lock bolt, with an active buzzer for alert feedback.
What You'll Learn
- Integrate R307 optical fingerprint sensor with ESP32 and implement 1:1 verification logic
- Design a multi-factor authentication state machine that merges MFRC522 RFID reads, keypad input, and biometric checks
- Control dual SG90 servos with PWM for precise compartment opening and locking, including position feedback routines
- Log access events with DS3231 RTC timestamps, save structured data to a microSD card, and display status on an OLED

Who This Kit Is For
Designed for advanced makers, B.Tech final-year students in ECE, EEE, and CSE working on IoT security projects, Smart India Hackathon teams developing healthcare access solutions, and professionals prototyping pharmacy automation or controlled substance management. If you need a full-stack embedded system with biometric logging, this kit delivers everything in one box.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to access your AI companion, which walks you through every wiring step and code line. For further troubleshooting, drop a message on WhatsApp — our team responds within hours.
Can I enroll more than one fingerprint or RFID card?
Absolutely. The firmware supports multiple users; you will learn to manage a database of authorized fingerprints and RFID tags, each linked to an ID for logging.
Does this kit work with refrigerated medications?
The enclosure is not refrigerated, so it's meant for ambient-temperature drugs. However, you can integrate a DHT22 sensor (optional) to monitor internal conditions and log them alongside access events.
Is the dispensing mechanism secure against tampering?
The servos hold the door closed with active torque when locked, and the stout enclosure resists forced entry. Combined with PIN/biometric protection, it provides strong physical and electronic security.
Fingerprint + RFID + PIN three-factor. Servo opens compartment. Logs dispensing event with timestamp and user ID.
