Interfacing Lm35 Temperature Sensor With Pic Microcontroller 16f877a Pdf

The complete code for this digital thermometer using lm35 and pic microcontroller is given at the end.

Interfacing lm35 temperature sensor with pic microcontroller 16f877a pdf.

In this tutorial we will learn how to interface lm35 temperature sensor with pic18f4520 microcontroller and display its output on the lcd module. Interfacing pic16f877a with lm35 temperature sensor ccs c the lm35 temperature sensor is three pin device vcc out and gnd with an output voltage linearly related to centigrade temperature. This page shows how to connect the lm35 sensor with pic16f887 and build a simple diy thermometer. That means if output is 300mv then the temperature is 30 degrees.

Lm35 mikroc pro for pic. The output of the lm35 temperature sensor is connected to analog channel 0 ra0 of the pic12f1822 microcontroller. In this project the pic12f1822 microcontroller runs with its internal oscillator 8 mhz mclr pin is configured as an input pin. The code is self explained with comment lines and just involves the concept of interfacing a lcd with pic.

In this tutorial we ll discuss how to interface the lm35 temperature sensor with a pic microcontroller. Using the adc to get the analog output voltage of the sensor then converting it back to celsius degrees and finally display the result on an lcd and also send it via serial port to a host pc to monitor the temperature remotely. A d result low register adresl a d control register 0 adcon0 a d control register 1 adcon1 learn more about adc in pic microcontroller here. Since the lm35 output varies with dependent to the temperature we need adc analog to digital converter module to measure this voltage.
