The DHT11 sensor has three or four pins, depending on the variant: VCC: Connect to 3.3V or 5V on your MCU (based on your sensor's specification).; Data: Connect to a digital I/O pin on your MCU (not ...

This Arduino project uses the DHT11 temperature and humidity sensor to measure the ambient temperature and humidity in a room, and displays the values on a set of LEDs. The sketch reads the ...

Now that we have completely understood how a DHT11 Sensor works, we can connect all the required wires to Arduino and write the code to get all the data out from the sensor. The following image shows ...

The aim of this work is to implement an innovative Weather Monitoring system and real-time alert system sing IoT. Monitoring temperature (t) and humidity with a sample size of 10 values with g power ...
