ESP32-CAM

Missing a visitor at the front door usually means missed package deliveries, keeping friends waiting outside, or missing unexpected guests. Standard doorbells only work if we happen to be sitting nearby and the chime is loud enough to hear. If we are stuck in a work meeting, listening to music with headphones, or away from home, it is easy to miss the ring, leaving…

We are all facing a huge transition in tech due to AI. In projects, we can run AI models on PCs, SBCs or even Cloud servers. In this tutorial, we are trying to see if we can run an AI model on a microcontroller board like the ESP32. To test this out, we are going to deploy and benchmark the 260K-parameter Tiny-LLM by Andrej Karpathy using his open-source llama2.c…

ESP32 Cameras have become a popular choice for building low-cost wireless cameras, smart surveillance systems, and even small AI projects. But today, there are several options available, from the original ESP32-CAM to newer ESP32-S3-based camera boards and compact boards like the XIAO ESP32-S3 Sense. At first glance, they may look similar, but there are…

Moving through unfamiliar environments is a challenging thing for visually impaired people. We have a lot of solutions, from sticks to obstacle-avoidance handheld devices on the market, to solve their problem. In the DIY world, a lot of makers have built obstacle-avoidance sticks using Ultrasonic sensors, IR sensors or even a PIR sensor and different variations of…

In modern day, the need for surveillance systems is increasing rapidly. We have a lot of recognized brands that offer such solutions. But can we extend the capabilities of a $5 ESP32-CAM module to build something similar?In this project, we are going to build an AI-Based No Parking Alert System using ESP32-CAM, in which, if someone parks their vehicle in front of the…

Imagine driving into a crowded parking area and not knowing whether a space is available or not. This project solves exactly that problem by building a smart, automatic parking space detection system using the ESP32-CAM and the CircuitDigest Cloud API. With just a button press, the device captures a real-time image of the parking area and sends it over the internet…

Have you ever watched a movie where a system instantly detects a person’s face, like in security doors or smart targeting systems, and thought, “This looks too complex to build in real life?” It might seem like something only high-end systems can do, but the reality today is very different. With compact and powerful modules like the ESP32-CAM, building an ESP32-CAM…

In our day-to-day life, huge amounts of waste are generated in homes, streets, offices, and public places. But the real problem is not just collecting the waste; it is separating it correctly. When biodegradable waste like food waste and leaves gets mixed with non-biodegradable waste like plastic bottles and metal cans, recycling becomes difficult and environmental pollution increases. Manual…

Many visually impaired people identify currency notes by touching them. But as people grow older, their touch sensitivity may gradually decrease, making it difficult to recognise the correct denomination accurately. Imagine an elderly shopkeeper in a small roadside store who has weak eyesight and struggles to identify the money given by customers. In such situations…

Think of a busy road where hundreds of riders pass every minute, some wearing helmets, many not, and imagine trying to monitor all of them manually. It’s almost impossible to keep track in real time. Now imagine a small device quietly watching the scene, capturing an image with a single trigger, and instantly telling you whether safety rules are being followed. That is exactly what this ESP32-…

This tutorial shows you how to build a real-time object detection system using the ESP32-CAM module and the CircuitDigest Cloud Object Detection API. The system captures an image on button press, sends it to the cloud via wireless or internet connection, retrieves the identified objects with name(s), how many there were and how confident (how much certainty the algorithm has) of the object…

Nowadays, everything is rapidly transitioning into the digital world, from the way we communicate to how industries operate and services are delivered. Traditional methods that once relied on manual processes are now being replaced by smart, automated, and interconnected systems. Building an automated attendance system using ESP32-CAM is a practical, affordable way…
