DESIGN AND CONSTRUCTION OF A WIRELESS TEMPERATURE TELEMETRY DEVICE
This project describes the development of a wireless temperature telemetry device with the use of a programmed microcontroller, temperature sensor, RF transmitter and receiver, and LCD for display as basic elements. The project is divided into two parts: the transmitter part and the receiver part.
In the transmitter part the temperature sensor measures temperature and then gives an output voltage corresponding to the sensed temperature (10mv/oC), the programmed microcontroller (Atmega328p) in this part then converts the analog signal received to a digital signal through its ADC and then sends it through the RF transmitter connected to it to the receiver part of the circuit.
In the receiver part of the circuit the digital signal is then received by the RF receiver and sent to the microcontroller connected to it, the signal value is displayed on an LCD.
This device can be used to monitor the temperature in extreme, remote locations. It can also be used in industries to monitor the temperature of rotary bodies as well as many more temperature measurement uses.
