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.
