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 best way to prove the weatherman wrong! These sensors are…

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 to existing WiFi network & creates a Web Server. When…

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 the data and stores it into a database. It also…

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 receives the data, validates it and then stores it into…

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 enter this as this url in the browser. In this…

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 presented in. The data that is collected is pretty raw….

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 pvc tube which is widely used by plumbers for the…

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 box gives us flexibility to add functionality and other features…

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 resistance depending on the direction. We connect this to an…

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 that the DS18B20 and BME280 sensors are working okay we…

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 supply for this sensor. It will be connected to pins…

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. We need to connect a 4k7 resistor between the power…

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 by POE (Power Over Ethernet). As we work through the…
