This project is intended to dispense safe drinking water by scanning RFID card by the user. The water dispenser uses IoT concept to verify RFID and record all transaction in the server.

IoT based prepaid Water Dispensing System

The sensor gateway was developed to acquire various digital and analog sensor data and controlling relay and pwm outputs from a cloud server or local smart phone app.

IoT based sensor gateway

Smart Bin

This was developed for a client who wanted to monitor the room temperature in a server room. When the temperature rose above a threshold the device would sound an alarm.
I used a thermistor to measure the temperature and used an AVR microcontroller to run the system. The PCB was designed in EAGLE.

Temperature monitoring system

The client wanted a complete tank driving simulator for training the soldiers to drive and using the gunnery system on the tank.
My job in this project was to develop an interface between the hardware in the simulation environment and the control system computer.
I used AVR microcontrollers to take all the hardware status and implemented UART communication for transmitting the status to the control system.

T-69 II G Tank Simulator for Bangladesh Army

The client wanted a pop up target system for firing practice and assessing their shooting efficiency.
I built this pop up device using high torque DC motors that could be controlled remotely with a XBEE RF module.
I also designed the 2 layered PCB using EAGLE.
