Web portal of heating - open hardware

-
I am offering a built-in web-based backend written in PHP that acts as a data collection gateway for users registered on the site. Each registered user chooses the hardware they use - the development board through which they send the data to the site.

The user has a choice of platforms:
- Arduino + Ethernet shield W5100 / W5500
- NodeMCU / ESP8266
- ESP32

The page allows you to record and view up to 6 temperatures, one of which is the control temperature that controls the heating in the house. Temperatures are recorded with DS18B20 sensors in 6pcs, which can be pulled up to tens of meters from the source. It is therefore possible to cover the entire household, outdoor areas, and so on. When power is active (3-pin connection).

Heating includes 2 modes:
- Automation - switches based on measured temperature targeting with optional hysteresis (+ -0.5 - 2 ° C) (to be implemented)
- Manual - Classically on request ON / OFF (to be implemented)

Of course, you can also represent the measured temperatures during the day and plot them directly on the web within 24 hours or 7 days. The site allows you to change the names of the rooms / senses from which data is taken, the page generates the source code for the microcontroller, shows the status of the connection of the board (whether it is connected, the time of the last received information). The user can record temperatures once in 30 seconds.

The system also offers real-time chat between registered users.
The application is brisk, it offers an interesting way to collect and represent data in a multiuser web application. Each user has a unique identifier that can upload the data to the page. From the administration interface, spammers (boards that send invalid data can be blocked).
Since Arduino boards with Ethernet shields that do not support HTTPS are also integrated into the system, both HTTP and HTTPS have to be varied.
Each device can send the data to the site once per minute (if it sends more often, the system discards the data) - prevents overloading the database + regularly erases old data.
The system uses a MySQL database and a series of tables for users, measured data, heating status.
If you are interested, PM me.

Web scraper via Arduino & NodeMCU & ESP32

Today, we will devote our microcontroller and its general use to a rather unusual purpose. Specifically, I will be talking about how I made a microcontroller from a webscraper. (If this can be called when processing your own backend information). As many of you know, a web scraper is a device that performs the task of retrieving information from that web site. The most wanted information from websites is e-mail addresses, phone numbers. Recently, however, this phenomenon is also used for a variety of statistical tasks where the scraper receives data on products, their prices, and evaluates them. Even similar devices are used as robots for trading with cryptomas or common names. At the most appropriate time (statistically) the robot pedal and bought another - a suitable menu with a rising tendency. In my case, I was interested in getting information from websites, specifically phone numbers and email addresses. We will therefore go directly to the realization. I have used 3 kinds

ESP32 control via UDP datagrams

Today I would like to point out the possibility of controlling the ESP32 development board by sending UDP messages for easy ON / OFF control. This is one of the easiest ways to send data, process it, and take action based on the information received. ESP32 is a platform that is used in most cases in connection with WiFi connectivity as a webserver or webclient, which connects to a remote server and POST, GET method, or with the integration of the MQTT protocol, sends data to a remote server / guest. Libraries for ESP32 written in C++ Arduino core (framework) also allows to use asynchronous UDP libraries for sending and receiving data. An interesting feature is asynchronicity, as they work in the "background" and the user does not have to program complex functions to accept connections, process information, etc. To send data to the ESP32 development board, we need a simple UDP client. In my case, I used the Windows version of the relatively well-known Packet Sender client. It

Biking on Google Maps - Arduino Leonardo (32u4) - HID device

Cycling is a very popular sport, also thanks to the successful athlete Petr Sagan. Passionate cyclists roam our roads and paths. However, as the weather is not always good, not only a fan of bicycles would like to ride from the comfort of home. So today I am bringing a way to do this, say, the augmented reality of Google maps. At the beginning we will go through the necessary hardware resources for the project and in the next step we will discuss their functionality. Hardware Components: Arduino (32u4 CPU) Leonardo  Magnetic reel switch  2x pushbuttons  To use the system, the user must turn on Google Maps, select any site in the world and switch to Street View mode. This ensures a ready interface for interacting with the bike (Arduin). Any type of bicycle can be used. Classic, road, mountain, treadmill. A magnetic contact must be fitted on the pedal and the structure. The main element of the system is the use of the Arduino Leonardo development board, which contains an AT
