ESP32 Smart Home Motion-Activated Lighting System

Nov 21, 2024 | hackster.io | Mechatronics Lab

Things used in this project This project explains how to create a smart home motion-activated lighting system using an ESP32 microcontroller, a PIR sensor, and an LED. The system detects motion and automatically controls lighting. It also integrates with the Blynk app for real-time monitoring and control. A web interface further enhances the system, offering live status updates and manual controls using HTML5, CSS3, JavaScript, and the Blynk API.
ESP32 Weather Data Logger with DHT Sensor (ThingSpeak + Goog

Nov 15, 2024 | hackster.io | Mechatronics Lab

Things used in this project In this project, you will create an ESP32-based weather data logger that reads temperature and humidity from a DHT22 sensor (connected to Pin D4). The data is uploaded to ThingSpeak for real-time visualization and logged into Google Sheets for storage and further analysis. This project is perfect for monitoring weather conditions over time and analyzing the data using Google Sheets' built-in capabilities.
ESP32 Weather Forecast System Using DHT and Firebase

Nov 14, 2024 | hackster.io | Mechatronics Lab

Things used in this project In this project, the ESP32 will collect temperature and humidity data using a DHT sensor (DHT11 or DHT22). The data will then be uploaded to Firebase, a cloud platform, where it can be stored and monitored. This system can be extended to trigger automations, generate weather forecasts, or perform other actions based on the data. Components Required:ESP32– Microcontroller with built-in Wi-Fi.DHT11 or DHT22– Temperature and humidity sensor.
ESP32-based Smart Greenhouse Control with DHT Sensor (ThingS

Nov 14, 2024 | hackster.io | Mechatronics Lab |Thing Speak.begin

Things used in this project Project Overview:This project uses an ESP32 board along with a DHT sensor (either DHT11 or DHT22) to monitor temperature and humidity inside a greenhouse. The data is uploaded to ThingSpeak, where it can be monitored and visualized in real time. Based on sensor readings, a relay module controls devices such as a fan and water pump to regulate temperature and humidity inside the greenhouse. Components Required:ESP32 Board– The microcontroller for IoT applications.
Temperature & Humidity Monitor with ESP32 and Home Assistant

Nov 14, 2024 | hackster.io | Mechatronics Lab |PubSubClient client

Things used in this project The DHT11 sensor will measure temperature and humidity, which the ESP32 will read and publish to Home Assistant using MQTT. Home Assistant will then display the data in real-time, and you can also set up automations or alerts based on the sensor readings.
Temperature & Humidity Monitor with ESP32 and Adafruit IO

Nov 14, 2024 | hackster.io | Mechatronics Lab

Things used in this project Creating a Smart Home Temperature & Humidity Monitor using the ESP32, a DHT11 sensor, and the Adafruit IO platform allows you to monitor temperature and humidity levels in real-time from anywhere with internet access. In this guide, we’ll set up the hardware and software to send live temperature and humidity data to Adafruit IO, where you can view it on a customizable dashboard.
Repeating Statements with a Counter Arduino and MicroPython

Aug 27, 2024 | hackster.io | Mechatronics Lab

Things used in this project ×1Breadboard (optional, for easier connections)×1×1In this section, we explore the for loop, a fundamental construct in programming for repeating statements a specified number of times. The for loop provides precise control over initialization, condition testing, and iteration, making it ideal for tasks where you need to execute a block of code iteratively with a counter.
Arduino and MicroPython a Sequence of Statements ESP32

Aug 25, 2024 | hackster.io | Mechatronics Lab

Things used in this project ×1×1×1×1Breadboard (optional, for easier connections)×1In this section, we delve into using loops to repeat a block of instructions in your ESP32 projects based on specific conditions. Loops such as while and do...while are essential for executing repetitive tasks, such as monitoring sensor inputs or implementing continuous operations until a condition is met or no longer true.
Taking Actions Based on Conditions Arduino And MicroPython

Aug 22, 2024 | hackster.io | Mechatronics Lab

Things used in this project ×1×1×1In this section, we explore how to execute specific blocks of code based on conditions in your ESP32 projects. This capability is essential for implementing responsive behaviors such as activating an LED when a switch is pressed or responding to sensor inputs. What We Will Learn in This Section:How to use conditional statements (if, if...else) in ESP32 programming. Implementing actions based on sensor readings or input states.
