Flame sensors are found from the simplest gas stoves to huge industrial plants There are different types of fire sensors -- some cheap, some expensive Yet they’re all built for...
Last time, I showed you how to setup the ESP32 development board with the Arduino programming environment This time, I will be building a simple ESP32 web server where data from a...
The DHT22 is a temperature and humidity sensor in one package It is widely used mainly due to its price but also because of it being robust and user-friendly In this NodeMCU...
There is, in fact, a way to create a NodeMCU ESP8266 WiFi jammer although technically, this is a deauther and not really a jammer A jammer sends out noise on the WiFi frequency...
The NodeMCU is an Arduino-compatible board that features the ESP8266 at its core It became popular because it is a WiFi-ready microcontroller by itself - no need for an Arduino...
I finally got my hands on a Raspberry Pi Zero W and started the usual tinkering For those unaware, this smaller version of the Raspberry Pi packs a 1 GHz CPU and 512 MB of RAM But...
You can use WiFi with the NodeMCU (ESP8266) even without a WiFi router All you need to do is create a NodeMCU WiFi Access Point and the device will now act as a WiFi gateway ...
Uploading sensor data to web servers is one of the core ideas for Internet of Things (IoT) Such data are often small-sized and are continuously updated over time And while HTTP...
So far, we've been using HTTP in our NodeMCU web servers and while it works, the protocol is not really the best way for sending and receiving small-sized data for IoT...
