A basic GUI that visualizes DHT11 sensor data collected by Arduino nano. Arduino reads the sensor data and sends them to PC through serial. The processing sketch reads the serial data from the COM ...

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 ...

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 communication. GND Ground ...

The DHT11 sensor senses humidity and temperature, and sends the information to digital pin 5 of Arduino MCU, as shown in Fig. 2. From Arduino MCU, humidity and temperature values are uploaded to the ...

I’ve tried the DHT11 sensor modules at both Vcc 3.3V and 5.0V, and at both voltages the humidity values are bad. dfrobot has introduced a V2 DHT11 sensor module that changes the 10K pull-up to 4.7K.

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 user sets ...
