With the rapid growth of IoT-based monitoring systems, staying informed about what’s happening in real time has become extremely important. Whether it’s detecting an intruder, monitoring equipment, or tracking activity, users need instant alerts without constantly checking dashboards or screens. Email notifications offer a simple and reliable way to receive detailed…

In our everyday lives, environmental conditions like temperature and humidity can have a big impact, whether it’s in your home, office, greenhouse, or server room. Imagine leaving your room for a few hours and suddenly discovering that the temperature had got too high or the air had become too humid. Keeping track of these changes in real time can be challenging,…

In recent years, the demand for smart security and automated monitoring systems has increased significantly due to growing safety concerns and the need for real-time surveillance. Traditional security systems often require continuous human supervision, which can be inefficient and time-consuming. With the advancement of embedded systems and Internet of Things (IoT)…

In this tutorial, we will learn how to send an email from your ESP32 microcontroller. This feature allows important details such as sensor data, time of occurrence, images, and system status to be sent through email in a clear and reliable format. It is especially useful for event-based alerts, maintaining records, and monitoring systems over a long period. By…

ESP32-CAM is a compact size, low-cost dev board with a camera, making it extremely convenient for camera-based applications. Even though it offers fewer GPIO pins compared to other ESP32 boards, it performs exceptionally well for focused tasks where imaging and connectivity matter the most. In this project, we’ll put the ESP32-CAM to good use by capturing a clear…

DigiKey has announced its Back to School Giveaway, and it’s open for submissions from August 26th to October 24th, 2025. The winners' announcement is expected around the 15th of November. This is a giveaway that happens every year, and the company sees this as a way to help students bring their creative engineering ideas to life.

The entry eligibility is for you to be a student with a…

 Since the coronavirus outbreak, building a contactless body temperature monitoring system has become essential for identifying those affected by the virus.  To solve this issue, temperature devices are often used to measure body temperature. These devices have non-contact IR temperature sensors that can measure the body temperature without any physical contact.…

Previously we built a smart container using weight as a measurement parameter to send alerts. Now in this IoT smart jar, we will check the level of a Jar using Ultrasonic sensor and send an alert email to the user. The level of Jar will also be displayed on a webpage hosted on NodeMCU ESP8266.

This smart Jar allows us to keep track of the stocks,…

We previously used NodeMCU to log temperature data in the Google sheet. Now here we are going to send data to Thinger.io IoT cloud and display it in an attractive graphical format. A BMP180 sensor is interfaced with NodeMCU ESP8266 to collect the temperature, humidity, and altitude data, which will be sent to the Thinger.io platform. In this tutorial, we will learn how…

Atmega16 is a low cost 8 bit microcontroller and comes with more number of GPIO’s than its previous version of microcontrollers. It has all the commonly used communication protocols like UART, USART, SPI and I2C. It has wide applications in robotics, automobile and automation industries because of its wide community support and simplicity.

Atmega16…

We are moving towards the World of Internet of Things (IoT), a technology which is going to play a very important role in the consumer and industrial electronics. Sending an Email from any Microcontroller or Embedded system is one of the very basic thing which is required in IoT. Here we create a demo IoT project where we use ESP8266 and MSP430 Launchpad…

You might have heard about Smart Refrigerator which can automatically order the food items which are running low in refrigerator, so inspiring from that we are here building a Raspberry Pi Smart Container using Load Cell and HX711 Weight Sensor. This Smart Container can tell you about its status like whether it is full or empty, by sending a mail to your Email ID. We…
