PROFESSIONAL PROJECTS (Firmware)
• Hubodometer: LTE based MQTT telemetry for hubo-
dometer. It pushes revolution count, speed, geo-
location etc to AWS cloud via mqtt using NRF9160
Nimbelink modem
• Cytotron: Medical treatment device with Magnetic
& RF guns. (MCU - ADuC 7026)
• Aquaria: Device for formation of water based on
Atmospheric dew point range. ( MCU – LPC2148,
ESP8266 wi-fi)
• Aquatron: Waste water treatment/filtering
device. ( MCU – ADuC 7026)
• Solar water heater controller: Instrument used to control temperature of water in the solar water
tank. (MCU - PIC16F886, PT100).
OTHER PROJECTS
• Heart rate monitor: MAX30100 optical pulse sensor interfaced with STM32F103C8T6 via I2C. Raw data
is processed to find peak to peak and then BPM.
• Finding Roll-Pitch-Yaw using MPU6050 interfaced
to atmega328p via i2c. Roll-Pitch is calculated
from both Acc & Gyro and applied complementary
filter. Yaw is calculated directly from Gyro.
• Graph plot on OLED (freeRTOS based): Explored
RTOS tasks, Semaphore, Mutex, Event Flags,
message Queue, Os-Timers on stm32f407.
• TV Remote decoder (IR): TSOP1738 interfaced
with stm32f103 to receive, demodulate and
decode 38KHz modulated IR signal from a TV
remote.
• Home automation using ESP8266: Explored MQTT
protocol in esp8266 to control an LED bulb
remotely. ESP8266 RTOS SDK is used.
• GSM based Remote water pump controller:
SIM800C is interfaced with STM32F103 via UART to
receive and control motor relays remotely by
SMS.
