Robo India presents tutorial on how to read temperature and humidity data through DHT11 sensor using ESP8266 wifi module on NODEMCU LUA platform. 1. Introduction: The DHT11 is chosen because it is lab calibrated, accurate and stable and its signal output is digital. Most important of all, it is relatively inexpensive for the given performance.

Apr 2, 2022 · In this tutorial, we will be using DHT 11 sensor to send Temperature and Humidity data to Arduino Cloud. Materials Needed. The very first step is to ensure that your PC has …

Interface single wire DHT11 sensor with NodeMCU and read the value of Temperature and Humidity from DHT11. Display the Temperature and Humidity value on a serial window.

Learn how to publish temperature and humidity readings from a DHT11 or DHT22 sensor via MQTT with the ESP8266 NodeMCU to any platform that supports MQTT or any MQTT client. As an example, we’ll publish sensor readings to Node-RED Dashboard and the ESP8266 will be programmed using Arduino IDE. Recommended reading: What is MQTT and How It Works.

Mar 24, 2024 · I am doing my first project using "NodeMCU ESP8266" & "DHT11 Temperature and Humidity Sensor Module" and trying to read temperature and humidity. However, I while trying to read the temperature I get the below result,

In this guide, we have learned how to build a DHT11/DHT22 web server with ESP8266 NodeMCU and Arduino IDE and how to display the sensor readings on a web page using an asynchronous server sent events web server. Additionally, new sensor readings will be updated automatically.

NodeMCU module, based on ESP8266 with onboard CP2102 USB-to-UART Bridge. It SHOULD be NodeMCU DEVKIT V1.0. - Fritzing part of NodeMCU v1.0 can be found HERE. - Blink NodeMCU on-board LED using Arduino IDE with esp8266 library, and more examples using ESP8266 core for Arduino.

Mar 22, 2017 · I'm using Arduino IDE for programming the NodeMCU. From where do I download the DHT.h / DHT11.h file / libraries for reading the temperature data for this setting? Some standard Arduino libraries work fine with ESP8266 (the microcontroller on your NodeMCU module). Others are written for a specific architecture and will not work on ESP8266.
