Digital Thermometer using PIC16F877A and LM35

This is a simple project showing you how to read LM35 analog temperature sensor using a PIC microcontroller and six seven segment (common cathod).In this tutorial we will make a practical use of multiplexed seven segment displays. We will use them to show current temperature usinga LM35 temperature sensor. The temperature sensors are connected to the ADC ports of the microcontroller, which takes in the anal ...

Digital Thermometer using PIC Microcontroller and LM35 Temperature Sensor

Thermometer can be easily constructed using a PIC Microcontroller and LM35 Temperature Sensor. LM35 series is a low cost and precision Integrated Circuit Temperature Sensor whose output voltage is proportional to Centigrade temperature scale. Thus LM35 has an advantage over other temperature sensors calibrated in Kelvin as the users don’t require subtraction of large constant voltage to obtain the required ...

PIC Digital Thermometer and Clock

Here you will find complete construction details including circuit diagrams, PCB layouts and PIC firmware (and the source code). The code was written in Proton PIC BASIC but the good news is that there is now a free version of this compiler available for download; AMICUS18. ** UPDATED 17th Aug 2013 ** There was a bug in the firmware that prevented the backup battery from being recharged correctly. ** UPDATE ...

A digital thermometer or talk I2C to your atmel microcontroller using pic microcontroller

Abstract: The Atmega8 microcontroller from Atmel has plenty of digital and analog input/output lines. It is the ideal device to develop any kind of measurement equipment. In this article we see how to interconnect the microcontroller to a linux PC over a physical RS232 interface without the extra MAX232 chip. Introduction A pre-requisite for this article is that you have the GCC AVR programming environment ...

chipKIT Project 1: Digital thermometer using an LM34 sensor

In Tutorial 3, we learnt how to use chiKIT ADC channels to read an external analog voltage and convert it into a digital number. We also discussed about interfacing a standard Hitachi 44780-based character LCD to the chipKIT Uno32 board in Tutorial 4. Now it’s time to implement the knowledge we have gained so far to make our first practical application using chipKIT, which is a digital thermometer. Since te ...
