Home Improvement DIY: WiFi Gas Detector with Text Alerts

Hey guys, back with another little project that I’ve been fiddling with for the past week. With kids around, every parent is thinking how to make their home safer for the little ones and for everybody in general. One of the most dangerous thing in the house can be the stove and since we have a gas-powered one, I always wondered why there are no simple gas detectors that can be used around the stove, just to ...

ESP32 Hands-On: Awesome Promise

The ESP32 is looking like an amazing chip, not the least for its price point. It combines WiFi and Bluetooth wireless capabilities with two CPU cores and a decent hardware peripheral set. There were modules in the wild for just under seven US dollars before they sold out, and they’re not going to get more expensive over time. Given the crazy success that Espressif had with the ESP8266, expectations are high ...

ESP8266 touchscreen WiFi light controller and clock

A couple of months ago I picked up cheap WiFi-controlled LED bulbs (one among dozens of very similar devices), after seeing them at a friend’s place.  This turned out to be an excuse to play with the ESP8266, which has inspired several hacks. I was overall very happy with these bulbs: decent Android and iOS apps and, compared to fancier solutions (e.g., Philips Hue or Belkin WeMo), they do not require any p ...

Web Controlled Servo using Arduino and Wi-Fi

In this post we are going to control a Servo Motor using a web browser with the help of Arduino and Wi-Fi module ESP8266. The ESP8266 will establish a connection between the servo and the web browser through the IP address and then by moving the Slider on the web page, the servo will move accordingly. Even by setting Port Forwarding in your router, you can control the Servo from anywhere in the world over t ...

WIFI Battery Monitor System – ESP8266

One of the main problem in battery powered projects is to choose/use the proper battery size/model/type. As market is flooded now with a lot of low quality batteries claiming thousands of mAh ( Ultrafire fakes stories is just an example) the only way to proper check them is to run a set of tests. A simple basic tester that will be able to monitor over the entire battery lifetime at least few parameters like ...

Internet Datalogging With Arduino and XBee WiFi

Introduction Are you looking to get your data gathering project hooked into the “Internet-of-Things”? Then check out data.sparkfun.com! It makes posting data to the web as easy as constructing a URL and POSTing it to a server. I wanted to create a quick project to test out SparkFun’s data logging service. Combining an Arduino, XBee WiFi module, and a variety of gas, temperature, and light sensors I built an ...
