To minimize hardware requirements we will make Internet clock without using RTC module. This is more accurate as compare to RTC clock. ESP32 is a Wi-Fi module and can be easily connected to the internet so we will use NTP (Network Time Protocol) and UDP (User Datagram Protocol) to fetch Time from the internet using Wi-Fi.
In this project we are going to explore the possibility of controlling AC appliances with the click of buttons on a webpage using internet. Using this IoT based home automation system, you can control your Home appliances from anywhere in the world. This web server can be run from any device which can run HTML applications, like Smart Phone, tablet, computer etc.
IOT based Security System with Voice Message Using ESP8266
This is another interesting IOT project in which we will build a Security system which can trigger an E-mail when it detects someone. This project has blend in the power of ESP8266, PIR sensor and ISD1820 Voice module. At the end of this article you would have built a fully functional Security system which can be Armed/Disarmed (Activated/De-activated) remotely via internet. You can record your own audio clip which will be played when a movement is detected and also send a mail with Date and time to a particular E-mail ID stating the intrusion. Cool enough…..!!!??
DIY IoT Based Raspberry Pi Surveillance Robotic Car
In this DIY session we are building a web controlled surveillance robotic car using raspberry pi and a webcam. This could be a useful and inexpensive security and spy tool, which have many configurable options and can be built in few hours. In this IoT Project, we are mainly using Raspberry Pi, USB web camera and two DC motor with Robot chassis to build this Robotic car.
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 can also monitor the weight of container in real time using web browser, and that’s make it a IoT project where you can monitor your container from anywhere using internet. Here the weight of the container will be updated in every 5 seconds on the web browser, this duration can be easily changed in HTML code file. We have set the threshold weight value of 300 gram to send the email about that “Container is Full”, this limit can also be changed.
