Today we will be working on a Water level indicator whose data can be monitored through a webpage over a local area network. The water level will be detected by using an ultrasonic distance measurement sensor.

HC-SR501 Motion Sensor usually known as the PIR sensor is used in many kinds of Security Alarm Systems and Motion Detector systems. Instead of emitting infrared signals, it absorbs IR signals and that’s why it is called PIR (Passive Infrared) Sensor.

A definitive and comprehensive vehicle accident and rash driving identification and alert system using NodeMCU. Unlike other projects across the internet, it has a fully functional and independent circuitry.

After the COVID-19 outbreak, the contactless temperature measurement devices are getting very popular and most of them use the infrared temperature sensor. This device measures the temperature of the person without any physical contact.

The fall detection system is very useful for elderly people. It can notify the concerned person or family member whenever it detects any fall and can reduce the risk of delayed medical attention.

You mostly have seen Data logging web server with real-time graphs and tables on ThingSpeak and other IoT platforms.

In this project, we are going to integrate Adafruit IO with Zapier to send Email Notifications whenever the data published in the Adafruit IO Feed. We are going to use NodeMCU and BMP180 sensor.

Conventional energy meter which we use in our households to measure Energy consumption is an offline device, so it has to be monitored manually.

Flood is a major known natural disaster that causes a huge amount of loss to the environment and living beings. So in these conditions, it is most crucial to get the emergency alerts of water level status at river beds in different conditions.

Many IoT cloud platforms have emerged in the last few years to cater to the increasing network of IoT devices.
