Design And Construction Of A Wireless Temperature Telemetry Device

This project outlines the development of a wireless temperature telemetry device that integrates a programmed microcontroller, a temperature sensor, RF transmitter and receiver modules, and an LCD display as its core components. The device is structured into two main segments: the transmitter and the receiver.

In the transmitter segment, the temperature sensor measures the ambient temperature and generates an output voltage proportional to the temperature (10 mV/°C). This analog signal is then converted to a digital signal by the microcontroller (Atmega328p) via its ADC. The digital data is subsequently transmitted wirelessly through the RF transmitter to the receiver segment.

In the receiver segment, the RF receiver captures the transmitted digital signal and relays it to another microcontroller, which processes the data and displays the temperature reading on an LCD screen.

This device is designed to monitor temperature in extreme or remote locations and has potential applications in various industries, including monitoring the temperature of rotary equipment and other temperature-sensitive environments
