LM35 Interfacing with Arduino Mega 2560

Arduino has been around since 2005 and it is one of the most popular cheap DIY (Do it Yourself) board available in the market. It is a single board complex circuit which has a microcontroller, reset switch, USB port for PC interfacing (serial communication) and input/output ports etc. The board has an open source hardware board designed for 8 bit Atmel AVR microcontroller or 32 bit Atmel Arm. Now a day’s Arduino has USB interface having six analog input pins and 14 digital input/output pins; earlier it had VGA port for interfacing with a computer. We can attach other kits and shield...

Interface LM35 Temperature Sensor with 8051 (AT89C51)

This simple project interface LM35 which is a very common Temperature Sensor giving high precision reading in terms of Analog Voltage with most popular 8051 Microcontroller AT89C51. LM35 gives analog reading and microcontroller process digital data so we have to use a midway converter from Analog to Digital i.e. AD0804 and display the result of a temperature on LCD. Temperature Sensor (LM35): LM35 looks like a transistor it will give you temperature in Celsius in terms of millivolt. For example if the temperature is 25 C its output will give you 0.25V provided that you must supply at least 1V to...
