In daily life, air quality has a great impact on human health. Based on the current demand for indoor air quality, an indoor air quality monitoring system is designed. The system can monitor PM2.5, ...

I tested the Pixel 9 Pro’s temperature sensor vs a thermal camera to see which is best — here’s the results : Read moreYou need to understand some physics ...

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 ...

Abstract: In this paper, a set of indoor temperature monitoring system is designed by using computer communication, database, sensor technology, etc., and the effective monitoring of temperature and ...

DHT11 is a temperature and humidity sensor. Its temperature range is 0 to 50-degree Celsius. It is a low cost and an efficient sensor that gives high stability. To measure the temperature it has a ...

DHT11 Module Pinout. The DHT11 module has a total of 3 pins. In which two are for power and one is for communication. The pinout of a DHT11 Sensor module is as follows: DATA Data pin for 1-wire ...

The dust detection module starts to detect the concentration of PM2.5, and transmits the detected data to the single-chip microcomputer through the ADC analog-to-digital conversion module. At the same ...
