An application for running a WiFi-connected DHT11 temperature/humidity sensor on an ESP32 MicroController. Includes C++ Arduino code for the ESP32 as well as a Node.js application. The Node.js ...

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 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 ...
