Arduino Based Data Logger (Temperature)

Engineeering Projects
arduino based data logger

The project described here is a simple Arduino Based Data Logger which can be used at any place where data is needed to be stored for further processing and monitoring. The project posted here basically store temperature, humidity with date and time in regular intervals on an SD card or a computer, or both. The wide range of operations and data rate of 12 samples per minute make this circuit more versatile and attractive at the same time. The data logging can be adjusted as per desire by changing the…

Fingerprint Attendance System using Arduino

The project posted here is a simple Fingerprint Attendance System using Arduino and can be very useful for any place where attendance is taken for maintaining registers like offices, schools, etc. Previously, we had posted RFID based attendance system, Arduino Fingerprint Sensor Lock, etc. The project posted here utilizes a thumb impression for taking attendance. The Fingerprint Attendance System using Arduino is based on a simple algorithm called matching algorithm and is compared with previously stored templates of fingerprints against the user’s fingerprint for authentication. Maintaining a register for attendance is…

ultrasonic water level meter transmitter circuit

Wireless Ultrasonic Water Level Meter using ATmega328 Water level indicator is one of the most popular projects over the internet but the problem with that is, it uses metal electrodes as a result corrosion is occurring. When we pass DC in water it starts to react with the metal in presence of oxygen and corrosion is occurring. This problem is minimized by using alternating current instead of direct current but there is always the risk of electric shock which can be dangerous if is handled by a non-technical person. By…

The project “Arduino and GSM Based Automatic Answering Machine” is designed to answer the phone call with prerecorded message when we are unable to attain call. Sometime in this busy world we might not be able to attain the phone call due to several reasons (generally when we are in bathroom or watching movie in cinema or forget mobile in home). These calls might be important i.e. call might be from office or business call which cannot be ignored. Thus, the project posted here receive the call after three rings…

Accident Detection and Alert System using Arduino

Engineeering Projects
author prototype of accident detection system

Today in this article we are going to build a project called Accident Detection and Alert System using Arduino UNO, GSM module, GPS module, and Vibration Sensor Module. The vibration sensor module used in this project is used to detect the change in linear velocity, displacement, or acceleration. The GPS module detects the exact location (longitude and latitude) and the GSM module is used to send all information to the mobile number assigned in the software code. You may also like the Car Lock System using Arduino and GSM modules.…
