Temperature and Humidity Monitoring System
In Stock
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.

This project involves controlling a DC motor’s direction using an 8051 microcontroller, with a buzzer and LED indicating the motor’s rotation state. When the DC motor rotates forward, the microcontroller keeps the buzzer and LED off. However, when the motor is rotated in reverse, the microcontroller triggers both the buzzer and LED to turn on as a visual and audible indication of the motor’s reverse rotation

- A rain alert system with an LCD display and buzzer, controlled by an 8051 microcontroller, is designed to detect rainfall and provide real-time notifications. The system uses a rain sensor to detect moisture or rainfall, and the microcontroller processes the sensor data. When rain is detected, the 8051 triggers a buzzer to alert the user audibly and displays the rain status on an LCD screen.

A Security Alarm Circuit using the LM358 IC is a simple yet effective system designed to trigger an alarm when unauthorized access or movement is detected. The LM358, a dual operational amplifier (Op-Amp), is used as a comparator to detect voltage changes from sensors like LDRs, IR sensors, or switches, and then activate a buzzer or relay.
