Again the same library can also be used with Arduino boards. Next the object lcd for class LiquidCrystal_I2C with I2C address of 0x27 and 16x2 type LCD display is initialized. The value is received ...

This project describes an inexpensive technique of using the DHT11 sensor for measuring temperature and relative humidity in parallel. It uses the PIC16F628A microcontroller to read the sensor output ...

You can use the DHT22 (or AM2302) humidity/temperature sensor and the Arduino UNO board to read data and ... if you want to use an LCD. I’ve chosen the DHT22 over DHT11 because it has a wider range of ...

The DHT11 sensor senses the surrounding room temperature and gives the result in degrees Celsius. Both the reference and the measured values are displayed on the Liquid Crystal Display (LCD). The ...

DHT11 Module features a temperature & humidity ... temperature automatically based on the Room's temperature. In this project, we are going to build a temperature-controlled fan using Arduino. With ...
