This project is not only an intelligent coffee machine with smartphone control but also allows you to graphically view the temperature trend. It can be controlled via Bluetooth or simply fill up with fresh water and the system starts automatically! Developed on Arduino Nano, it uses an ST7920 display, an HC-05 Bluetooth module, a Dallas…
In this project we will see how to make a thermometer to measure the temperature in the room with a measuring range from 10 degrees to 35 degrees Celsius and an accuracy of 0.5 degrees. The temperature is displayed on the WS2812 LED bar containing 50 diodes. Characteristic of this thermometer is that in addition…
With this project we will see how to make a solar powered wireless weather station using an ESP32 WiFi module and some common weather sensors. The weather station is fully solar powered, so you don’t need to worry about external power. It can be installed in a remote location without having to lay long cables…
The following tutorial demonstrates how to interface multiple DS18B20 on a single bus with Arduino and get temperature readings from each of them. This feature can be a huge advantage when you want to control many DS18B20s distributed over a large area. More info
There are a wide variety of temperature sensors compatible with Arduino, ESP32, ESP8266 and other development boards. So, it can be difficult to to pick up the most suitable sensor for your project. In this article, we’ll compare 6 widely used temperature sensors: DHT11, DHT22, LM35, DS18B20, BME280 and BMP180. More info
Thanks to PHP and a temperature sensor, we’ll see how to operate relays and control GPIO pins with a Raspberry Pi. Using AJAX and installing Apache web server on the Pi, this maker is able to control his Christmas lights using any mobile phone, tablet or laptop. All you need is: Hardware requirements Raspberry Pi…
Thanks to the Fishino board, we will make an existing fish tank smart, and we will place it in the IoT world. By now, technology has made way in our daily life as well, and the home automation becomes every day more familiar: it is easy to think, for example, to a heating…
The AAduino is an Arduino compatible microcontroller board, created by Swedish embedded systems engineer Johan Kanflo, that’s the size of a AA battery. The AAduino is designed to fit comfortably inside of one of the bays of a standard 3xAA battery holder, resulting in a reasonably powerful, wireless node will endless application possibilities. The AAduino…
