The compact DHT11 sensor module is available in a single-row package with four pins, making the interconnection very convenient. Out of the four pins, only three are required (VDD-GND-DATA), and the ...

The project integrates an Arduino with a DHT11 sensor for measuring temperature and humidity, along with an RTC DS3231 module for maintaining real-time clock functionality. The Arduino periodically ...

Based on the slot counted for defined interval motor speed is computed. Along with this current and power consumption of the motor also measured using the INA 219 current sensor module. DHT11 sensor ...

To build your very own IoT rain checking system, you will need a Raspberry Pi 3 Model B, a DHT11 Temperature & Humidity Sensor (4 pins), and a raindrop sensing board, which can be purchased for ...

This paper explores the realm of home automation, focusing on the development and implementation of a sophisticated system leveraging Internet of Things (IoT) technology. The core of the proposed ...

This proposed work introduces the NodeMCU(ESP8266) microcontroller, a variety of sensors (including the DHT11, MQ135, and PIR), a display, and a buzzer all working together to create a novel smart ...
