Weatherstation - Project Overview

This entry is a quick overview of how the weatherstation operates. Previous posts go into more detail about how the device was programmed and constructed.

Weatherstation - Receiving the data

In a previous post, I went over how the weatherstation data will be accessed--an Arduino-based webserver. However, this implementation had a major limitation: no data logging or visualization. I decided to switch to uploading the received data to Xively, which provides the data logging and visualization.

Weatherstation - Protoboard

Now that I have the weatherstation working on a breadboard, it's time to solder it onto a protoboard for a more permanent solution.

Robot - Wireless Communication: Receiver

In this post, I'll go over how to make the robot respond to commands sent by the transmitter. You'll need the parts outlined in a previous post. These parts include a motor driver, 433 MHz receiver, and some Arduino-compatible device. The robot chassis has limited space, so I used an Arduino nano clone.

Robot - Wireless Communication: Transmitter

Now that the robot can respond to commands programmatically, the next step is to get the robot to listen for and respond to wireless commands. RF communication will be accomplished using the same library (VirtualWire) and components as my previous post, entitled Arduino Weatherstation – RF Communication. 

I'll split this part into two posts. The first will go over how to make the transmitter. The second will detail how to get the robot to respond to the transmitter's commands.

Robot - Introduction

I've begun working on a remote-controlled robot with a friend. It consists of a tank chassis and two DC motors. On the left is a picture of the chassis after assembly. The main goal of this project is to design a robot that can be controlled wirelessly by the user. Ideally, the robot will be controlled via two joysticks that can operate both treads independently.

In the next few posts, I will go over the components required to get an Arduino to control the robot directly.

Weatherstation - Internals

The weatherstation's internals are pretty much complete. I just have to solder the antennas onto the transmitter/receiver and the headers onto the barometric pressure sensor. I'll split this entry into three parts: first I'll go over how I made the antennas, second I'll go over the parts/operation of the transmitter, and third, I'll go over the operation of the receiver.

Arduino Weatherstation - RF Communication

I'm still waiting on my SparkFun Redboards. In the meantime, I received one 433 MHz transmitter and one 433 MHz receiver. Since I have a TI MSP430G2553 and a Duemilanove lying around, I thought I'd get them "talking" to each other.

Arduino Weatherstation - Temperature

I ended up purchasing a DHT22/AM2302 sensor, so I quickly put together a rudimentary Arduino sketch to read the temperature and relative humidity and calculate the dew point.

Arduino Weatherstation

I'm currently gathering the components to make an Arduino-powered weatherstation. Currently, I plan to measure temperature, barometric pressure, and relative humidity. One Ardiuno will sit outside, preferably near an outlet and measure and transmit weather data via a 433 MHz transmitter. The second Arduino will have a 433 MHz receiver and will receive the first Arduino's weather data, displaying real-time stats.
