LoRa and TTN

• Dragino LG01 gateway, TTgo T-Beam esp32 LoRa devices are used.

• Configured and Registered Dragino gateway in The Things Network site(TTN).

• Developed code in Arduino IDE and burned it in the LoRa devices.

• Created application in TTN and registered LoRa device in application console.

• Noted down the latitude, longitude, Satellite and GPS time readings from LoRa devices in The Things Network site.

CODE

E-health gateway using IoT

• Implemented a prototype of E-Health gateway Using IoT.

• Used LPC2148 microcontroller on ARM board and GSM modem with SMA Antenna.

• Connected Temperature and pulse rate sensor to the board.

• Developed the code in Kiel IDE and burned it to the board.

• Using the Given frequency of the Antenna calculated the theoretical losses and compared to the actual losses obtained from the Network

• Results were observed in the LCD panel connected to the board and through the website remotely.

CODE

DISTANCE CALCULATION USING ULTRA-SONIC SENSORS

• Ultrasonic sensor is a great tool to measure distance without actual contact and can measure small distances precisely

• Its basic principle is ECHO. By using ECHO time we measure the distance.

• Ultrasonic sensor is connected to Arduino for calculation and LCD for displaying distance.

• The code is developed in Arduino to calculate the distance from the travelling time (ECHO time) and speed of the sound.

CODE

SPEAKER USING OPAMP

audio amplifier is built around popular amplifier LM386 (IC1), an 8-ohm, one-watt speaker (LS1), four capacitors and a few other components. A 6V battery is used to power this project
