* This is a free software with NO WARRANTY. * Temperature is displayed on 1602 LCD screen (I2C LCD).
* Interfacing PIC12F1822 microcontroller with LM35 analog temperature sensor. The I2C LCD is initialized with an I2C address of 0x4E: The hardware I2C module of the PIC12F1822 is initialized with a clock frequency of 100KHz (100000Hz): The I2C LCD driver file is included with the line: To be able to compile the C code, a small I2C LCD library for MPLAB XC8 compiler is required which can be downloaded from the following link:Īfter the download, add the library file ( I2C_LCD.c) to project folder.

The C code below is for MPLAB XC8 compiler, it was tested with version 2.00 installed on MPLAB X IDE version 5.05. Interfacing LM35 sensor with PIC microcontroller C code: In this project the PIC12F1822 microcontroller runs with its internal oscillator 8 MHz, MCLR pin is configured as an input pin. The output of the LM35 temperature sensor is connected to analog channel 0 (RA0) of the PIC12F1822 microcontroller. (All grounded terminals are connected together) Project circuit schematic diagram is shown below. Interfacing PIC microcontroller with LM335 sensor circuit:
Calibrated Directly in ° Celsius (Centigrade).If the output voltage = 370mV -> temperature = 37☌ If the output voltage = 200mV -> temperature = 20☌
If the output voltage = 100mV -> temperature = 10☌ If the output voltage = 10mV -> temperature = 1☌ The LM35 output has linear +10mV/☌ scale factor means the following: The compiler used in this project is Microchip MPLAB XC8 (MPLAB X IDE with MPLAB XC8 compiler). Temperature data is displayed on 16×2 LCD screen (I2C LCD). This project works also with DFRobot I2C LCD displays.

This post shows how to build a simple thermometer using PIC12F1822 microcontroller and LM35 analog temperature sensor. Since the LM35 output varies with dependent to the temperature we need an ADC (Analog-to-Digital Converter) module to measure this voltage. The LM35 temperature sensor is a three pin device (VCC, OUT and GND) with an output voltage linearly related to Centigrade temperature.
