When debugging an electronics circuit or testing a new hardware design, often times I tend to check if the components on the board are getting hot abnormally by touching them. And if something is messed up (which usually is in the first try) these components could get as hot as 80°C or more burning not only the component but also my finger along with it. After burning my…
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…
This guide shows you how to build a motion detection system that sends instant WhatsApp alerts using the compact XIAO-ESP32 development board. When the IR sensor detects movement, the board immediately transmits a notification to your phone through the CircuitDigest Cloud platform. This wireless approach eliminates the need for GSM hardware or SIM cards, relying…
This project shows how to send instant WhatsApp alerts from a Raspberry Pi Pico W using WiFi and CircuitDigest Cloud WhatsApp API. The Pico W reads data from a rain sensor and, when moisture is detected, sends a notification directly to your WhatsApp. No GSM module, SIM card, or cellular hardware is required and everything works over a secure HTTPS request. The same WhatsApp notification…
In this tutorial, you will learn how to send WhatsApp messages from Arduino UNO R4 WiFi using the CircuitDigest Cloud Whastapp API. Instead of using a GSM module, SIM card, or complex WhatsApp Business API setup, this method allows your Arduino to send alerts over WiFi using a simple HTTPS request. This makes it much easier and more cost-effective to add real-time…
This ESP32 WhatsApp notification project shows how to send real-time WhatsApp alerts directly from an ESP32 using WiFi and the CircuitDigest Cloud WhatsApp API. The ESP32 reads sensor data, checks for a defined condition such as high temperature or motion detection, and immediately pushes a WhatsApp alert to your phone. And the best part is, you do not need a…
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…
In this section, we focus on one of the most immediately useful capabilities of the LiteWing Flight Positioning Module: precise height measurement using the VL53L1X time of flight sensor (ToF). Before implementing any control logic, it is essential to understand both the fundamentals of how the sensor measures distance and how the flight controller exposes this…
In this project, we’re making an ordinary two-wheeler helmet smart using an RF Transmitter & Receiver. The best part: this Arduino-based smart helmet is simple to build and does not require advanced engineering knowledge or complex components.
