Jeremy Morgan‘s mini weather station is IoT enabled and uses Raspberry Pi to measure temperature, humidity, atmospheric Pressure, and light intensity in Lux. It is capable to send the results to Google Spreadsheet on your Google Drive or an ASP.Net Web API on your website.

Benhur.Goncalves shared his design of an Arduino-based Wristwatch that features Pedometer along with Temperature, Altitude and Compass sensors.
Arduino Pedometer wristwatch
Hi folks! Last few days I’ve been obsessed with the idea to make my own watch from arduino parts, but something cool I could use and say I did it myself. So I found out there was a sensor board (commonly named GY-87) which had three sensors on it: HMC5883L (compass), BMP085 (pressure, altitude, temperature) and MPU6050 (accelerometer and gyroscope). With it, via I2C, I could add an Arduino Pro Mini, and an I2C Oled Display and make a watch capable of having all this information, plus a pedometer (by analysing accelerometer data).
Cool enough, it was incredibly easy to make, and you will just need some cheap parts, a small amount of Eagle PCB knowledge, some skill on making your own PCB board, and preferably a cheap watch to unmount and get the bracelet / carcass.
Before start, I’ll just post some pictures of previous versions I made so you can have an idea of the challenges you’ll face, and stuff you can add if you like. Let’s get going!
Team TAHMO is planning to build a network of 20,000 weather stations throughout sub-Saharan Africa for better weather forecasts, early warnings, and climate observations, which will eventually lead to improved food production in Africa.
TAHMO aims to build a network of 20000 weather stations in Africa
TAHMO stands for “Trans-African Hydro-Meteorological Observatory”, a program that aims to design, build, deploy, and operate a network 20,000 weather stations in sub-Saharan Africa (www.tahmo.org). Presently, we have pilot stations in Senegal, Chad, Nigeria, Uganda, and South Africa and “pilots at scale” in Ghana and Kenya.
TAHMO stations have to be be affordable and robust. For example, unlike standard weather stations, there should not be any moving parts as these are quickly affected by dust and insects. Maintenance so be limited to some simple cleaning. The network makes use of the availability of cell-phone coverage that has reached most of Africa over the past decade.
Presently, we work with stations developed by Decagon that come close to TAHMO specs. These stations cover all standard meteo measurements such as air temperature and relative humidity, wind speed and direction, incoming solar radiation, and barometric pressure.
This instructable describes in detail the setting up a full-featured weather station that records air temperature, relative humidity, and ground surface temperature right below the weather station. The project uses Phidgets SBC3 computer board, which is powered by an 18-watt solar power along with a battery backup.

I have always enjoyed reading/doing projects that involve sensing various environmental parameters and recording them. This Solar-powered outdoor weather station built upon the Arduino platform measures the ambient temperature, humidity and barometric pressure, and send these parameters to a PC using XBee RF modules. The measurements are recorded on the PC and presented in nice charts showing their temporal trends.

The beauty of this project is that the outdoor module is fully powered through a Lipo battery which is charged through a solar panel. Sensors used in this project are DHT22 for temperature and relative humidity measurements, and BMP0805 for measuring barometric pressure.
