Have you ever wanted to have sensors scattered all around your house and garden reporting their temperature regularly to a central server? Then, this IoT project might be the solid launching point for you! This project uses ESP8266 NodeMCU as the control device that easily […]

A fantastic feature of any WiFi-enabled microcontroller like ESP8266 NodeMCU is the ability to update its firmware wirelessly. This is known as Over-The-Air (OTA) programming. What is OTA programming in ESP8266? The OTA programming allows updating/uploading a new program to ESP8266 using Wi-Fi instead of requiring […]

Want to add little graphic pizzazz to your ESP8266 IoT projects? Or maybe you want to display IP address of your ESP8266 without resorting to serial output. These super-cool OLED (Organic Light-Emitting Diode) displays might be the perfect fit! They’re super-light, almost paper-thin, theoretically flexible, […]

Every once in a while you’ll come across an idea where keeping time a prime concern. For example, imagine a relay that has to be activated at a certain time or a data logger that has to store values at precise intervals. The first thing […]

ByAbhishek Bakolia Jun 05, 20190 RTC or Real Time Clock is the most commonly used module in Electronics and embedded devices to keep track of time. But the problem with RTC is that the microchips in computers are not that much accurate and they can only provide […]

Over the past few years, the ESP8266 has been a growing star among IoT or WiFi-related projects. It’s an extremely cost-effective WiFi module that – with a little extra effort – can be programmed to build a standalone web server. How cool is that! What is […]

Its summer, you’re sweating heavily and all you really want to know is why the weatherman predicted this morning that today’s relative temperature would max out to 20°C while it feels more like 25°C. Enter the DHT11, DHT22/AM2302 Digital Temperature & Humidity Sensor from AOSONG – the […]

Don’t let the smartphone weather apps or commercial weather stations(that feeds you with data from stations based miles away) ruin your outdoor plans. With this IoT project you can be your own weatherman! This project uses ESP8266 NodeMCU as the control device that easily connects […]

The Internet of Things (IoT) has been a trending field in the world of technology. It has changed the way we work. Physical objects and the digital world are connected now more than ever. Keeping this in mind, Espressif Systems (A Shanghai-based Semiconductor Company) has released an […]

Podcast: Descargar (149.4MB) Cuando creamos proyectos IoT con Arduino, tenemos varias maneras de monitorizar los datos que captamos a través de los sensores. La más básica y que requiere tener el dispositivo conectado a un ordenador es a través del monitor serie. Si tenemos algún display como un […]

Arduino Weather Station Project Part 10: Send Data to the Cloud In the final part of this project we configure the controller as a web client. We transmit the station data to a cloud server every 60 seconds. The cloud server it connects to processes […]

Weather Station Web Server Client (Part 10) In the last part of this project we configure the weather station controller as a web client. We send the data from the sensors connected to the controller to a web server via the Internet. The web server […]

Weather Station Web Server (Part 9) The software sketch shown below turns the weather station into a basic web server. This allows you to connect to the station using a web browser of your choice. Using the static IP address assigned to EtherTen board we […]

Getting Data from the Weather Station Now that we have assembled the weather station the next part of the project is to look at different ways to get data from the controller. Listed below is the data that is available and what units they are […]

Assemble the Weather Shelter (Part 7) The weather shelter was put together using a collection of plastic plumbing parts that are available from your local hardware store or depot. Some of the parts can also be recycled from building sites. We used a 100mm plastic […]

Hooking Up the Arduino Controller Box (Part 6) We decided to mount the Arduino board (Freetronics EtherTen) and shield inside a IP66 rated plastic box. We could have mounted the Arduino inside the weather shield but it would have been a tight fit. This controller […]

Hooking Up the Davis Anemometer (Part 5) Once we have confirmed all the other sensors are working okay we now hookup the last sensor which is the Davis anemometer. This device has two sensors. The wind direction is measured using a potentiometer that changes it’s […]

Hooking Up the Hydreon RG-11 Rain Sensor (Part 4) Observation: The Hydreon sensor is not as accurate as a tipping bucket rain gauge. It tends to read high in comparison. However this sensor will detect rain before a tipping bucket gauge. Once we have confirmed […]

Hooking Up the Bosch BME280 Temperature, Humidity and Pressure Sensor (Part 3) Once we have connected up the DS18B20 and tested it with the sketch we can hookup the BME280 sensor. We are connecting up the sensor using I2C communications. We are using a 5V […]

Hooking Up the DS18B20 Temperature Sensor (Part 2) The first sensor we connect up is the Dallas DS18B20 temperature sensor. We need to use a waterproof version as the sensor will be mounted outside the weather station shelter but protected by the wind temperature cover. […]

Overview (part 1) In this project we are putting together a Weather Station using a variety of sensors. The platform being used is an Arduino board (Freetronics EtherTen) with built in Ethernet. This will provide communications to the sensor along with a power source provided […]
