Temperature and Humidity Monitoring System
A Temperature and Humidity Monitoring System using Arduino and a DHT11 sensor that measures and displays real-time temperature and humidity data on the serial monitor.
Description
The Temperature and Humidity Monitoring System uses an Arduino and a DHT11 sensor to measure environmental temperature and humidity levels. The DHT11 sensor collects real-time data and sends it to the Arduino, which processes the data and displays the temperature (in °C) and humidity (in %) on the serial monitor. This system is useful for environmental monitoring, home automation, and weather forecasting applications.

The Conveyor Belt Object Counter using LDR and 7-Segment Display with the 8051 microcontroller is designed to count objects passing in front of an LDR (Light Dependent Resistor) sensor. The system works by detecting light interruptions when an object crosses the sensor, causing a change in the LDR’s resistance. The microcontroller processes this change and increments an object count. The count is then displayed on a 7-segment display.

A Flip-Flop LED Flasher is a simple electronic circuit that alternately turns two LEDs on and off in a continuous loop, creating a blinking or “flashing” effect. It’s commonly built using transistors, resistors, capacitors, and LEDs, forming an astable multivibrator — a basic circuit that oscillates between two states without any external triggering.
It’s often used for decoration, indicators, or learning basic electronics.

A Visitor Counter automatically counts the number of people entering or leaving a room using an IR sensor. The count is displayed on a 16×2 LCD, and a buzzer can alert when a specific limit is reached. This project is widely used in shops, libraries, offices, and events to monitor occupancy. It demonstrates sensor interfacing, counting logic, and real-time display using Arduino.
