In this post we are going to learn about strain gauge based load cell. We will be exploring what Strain Gauge is, what Load Cell is, temperature effect on strain gauge, temperature compensation with Wheatstone bridge and Load cell amplifier HX711, and finally we will learn how to build an Arduino based weighing scale machine […]
ECE/EEE Final year projects
RFID based Attendance System Using Arduino
In this post we are going to construct a RFID based attendance system, which can record attendance of 12 students / staffs for a given time window and this system can record up to 255 attendances per person. By Girish Radhakrishnan What is RFID Attendance System We don’t need any introduction regarding the RFID based […]
SMS Based Water Supply Alert Circuit
In this post we are going to construct a circuit which will notify the user via SMS if the water supply to you area / home is initiated. It can show the time when the water is begin to supply and ended, average water flow speed in liter per minute and total water delivered to […]
Incubator Using Arduino with Automatic Temperature and Humidity control
In this post we are going to construct an incubator using Arduino which can self-regulate its temperature and humidity. This project was suggested by Mr. Imran yousaf who is an avid reader of this website. By Girish Radhakrishnan Introduction This project was designed as per the suggestions from Mr. Imran, but some additional modification is […]
SMS Based Pump Controller with Automatic Dry Run Shut Off
In this post we are going to construct a SMS based water pump controller with automatic shutdown of pump when no water flow through the pump is detected. We will also construct another much simpler automatic dry run preventer circuit without GSM in the next half of the article. By Girish Radhakrishnan What is Dry […]
Buck Converter Using Arduino
In this project we are going to step down 12v D.C to any D.C value between 2 and 11volts. The circuit which steps down the D.C voltage is known as buck converter. The output voltage or step down voltage needed is controlled using a potentiometer connected to arduino. By Ankit Negi INTRODUCTION TO CONVERTERS: There […]
