This project helps to detect the temperature and humidity of room as soon as it detects the human body. Arduino The Arduino is a microprocessor. A Microprocessor is a compact programmable computing ...

// Connect pin 2 of the sensor to the data pin defined on your Arduino // Connect pin 4 of the sensor to GND // Connect a 10K resistor between pin 2 (data) and pin 1 (VCC) of the sensor ...

Abstract: This paper presents designing and implementing an Automatic room temperature control system using the Arduino and DHT11 sensor. The fan speed control system has also been proposed. Here, the ...

Numerous studies have shown that the indoor temperature and relative humidity at workplace significantly impacts workers’ comfort and productivity. The first step towards optimizing these two ambient ...

LAST week it was rain. This week, our mini weather station will measure temperature and humidity. And by using a second BBC micro:bit, we can get the readings before heading outside. First, we need a ...
