Visualizing Temperature and Humidity Data using ESP8266 in Cayenne
Temperature and humidity play crucial roles in industrial processes, and monitoring and controlling them is essential for optimal production conditions. Temperature and humidity sensors are deployed in process control systems to uphold specific environmental...
IoT Smart Gardening System – ESP8266, MQTT, Adafruit IO
Gardening is always a very calming pastime. However, our gardens' plants may not always receive the care they require due to our active lifestyles. What if we could remotely keep an eye on their health and provide them with the attention they require? In this article,...
MCP3008 with ESP8266 for Analog Moisture Sensors – SPI
In this tutorial. we will read 2 analog sensor data from ESP8266. Remember that there is only 1 ADC in the ESP Modules, so only one analog sensor can be connected to the hardware. Thanks to MCP3008, we can now read eight different analog sensor data from ESP Modules....
NodeMCU and RGB LED Strip with Adafruit IO – Arduino IDE
In this tutorial, we will connect an RGB LED strip of 5 meters to a NodeMCU and control them via adafruit IO. A combination of 3 LEDs—RED, GREEN, and BLUE—makes up an RGB LED. Red, green, and blue can be combined to create any color. RGB LEDs may produce a variety of...
IoT Weather Station Using NodeMCU-Micropython and an OLED display
Introduction In this post, we will see how to make a weather Forecast Station, which will display the weather of any location using a Nodemcu flashed with MicroPython.We will read a JSON file containing weather data from https://www.metaweather.com/ and display...
Smart Traffic Light System using NodeMCU(ESP32)
In this tutorial, we are going to make an IoT based Smart Traffic Light system. We will connect the lights by using ESP32. Let's begin! Contents: IntroductionMaterials RequiredThe CircuitCode and it's ExplanationThe Final Run Introduction First of all, we will create...
4×4 Keypad Door Lock using NodeMCU with E-Mail Alerts
This project will show you how to interface a 4x4 Keypad with the NodeMCU to make a simple code-based door lock. Entering the wrong code three times in a row or changing the existing code will send an E-mail alert to the specified recipient or the owner of the...
