Creating Smarter Realities with AI, IoT, & Robotics
I am Sreehari Viju, a 9th grade student from Trivandrum building innovative AI, IoT, and robotics projects — exploring the convergence of hardware, software, and artificial intelligence.
Technical Expertise
A curated set of technologies and domains I actively experiment with and develop on.
Arduino
Working with Arduino microcontrollers to build basic logic circuits, sensor interfaces, and automated hardware projects.
ESPs (ESP8266/ESP32)
Building IoT devices and smart networks using Wi-Fi enabled ESP boards for remote monitoring and control systems.
Raspberry Pi
Utilizing mini-computers for slightly more complex automation tasks, basic AI scripts, and networking applications.
Featured Projects
Pioneering real-world applications of cutting-edge tech. Built end-to-end as a student in Trivandrum.
Jarvis AI Assistant
A highly intelligent voice-controlled digital companion capable of handling automated system triggers and context-driven conversational prompts.
Smart Fire Detection System
Real-time emergency scanning and tracking using sophisticated telemetry arrays and automated NodeMCU alarms for early warning.
Real-Time IoT Dashboard
A low-latency dashboard for remote device telemetry. Aggregates NodeMCU sensor feeds over a visual grid interface.
Smart Robotic Arm
Arduino-controlled 6-DOF robotic arm with servo motors for automated pick-and-place operations and repeatable motion sequences.
Smart Plant Watering System
ESP8266-based automatic irrigation system with soil moisture sensors and real-time mobile alerts via MQTT.
RFID Security Lock
RFID-based door access control system with Arduino, LCD display and dual-mode keypad authentication.
Line Following Robot
Autonomous robot navigating black-line tracks using a 5-sensor IR array and real-time PID speed control.
Weather Station
Raspberry Pi-powered local weather station with real-time temperature, humidity, and pressure monitoring with data logging.
Obstacle Avoiding Robot
Autonomous Arduino robot using three HC-SR04 ultrasonic sensors for 180° obstacle detection and intelligent path avoidance.
GPS Vehicle Tracker
ESP32 + NEO-6M GPS tracker streaming live location to a Firebase-backed Google Maps web dashboard with geofence alerts.
Smart Video Doorbell
Raspberry Pi Zero W doorbell with live MJPEG streaming, PIR motion detection, and instant Telegram snapshot notifications.
Gesture Control Glove
Wearable Arduino glove with five flex sensors and MPU6050 IMU for wireless 8-channel gesture-based robot control.
Voice-Controlled LED Strip
ESP32-driven WS2812B addressable RGB strip with on-device voice recognition, music-reactive FFT modes, and web control.
Automatic Pet Feeder
ESP8266 smart feeder with NTP-synced scheduled dispensing, load-cell portion sensing, and Telegram meal alerts.
Smart Safety Helmet
Arduino safety helmet detecting G-force impacts and gas hazards, sending instant GSM SMS alerts to emergency contacts.
NTP Smart Clock
ESP8266 internet clock syncing with NTP servers, displaying time, date, and temperature on cascaded MAX7219 LED matrices.
Pi Security Camera
Raspberry Pi 4 dual-camera surveillance system with MotionEye, smart motion zones, and secure remote access via Tailscale.
Mini Quadcopter Drone
Scratch-built 250mm quadcopter with a custom Arduino 250Hz PID flight controller and MPU6050 for self-stabilizing flight.
