In addition to air quality, Raspberry Pis have also become a popular platform for low-cost weather and climate monitoring systems. Amateur weather enthusiasts and citizen scientists are using the small computers paired with outdoor sensors to build their own automated weather stations. These Raspberry Pi weather stations can measure and log a variety of real-time meteorological data like temperature, humidity, barometric pressure, wind speed and direction, solar radiation levels, and more.

Some examples of notable Raspberry Pi weather station projects include Davis WeatherLink, Rain Machine Pi Weather Station and METNO Pi Weather Station. These open-source platforms provide GPIO pinouts for connecting common weather sensors, sample code for reading sensor data, and web or mobile interfaces for visualizing measurements. With just a few environmental sensors, a Raspberry Pi, and power source, anyone can set up their own basic automated weather station for under $200.

Across the world, individuals are using these DIY Raspberry Pi weather stations to monitor hyperlocal weather patterns in their backyards, farms and remote areas that may otherwise go unrecorded. Citizen scientists are contributing their data to larger weather monitoring networks and databases. For example, Weather Underground's Personal Weather Station (PWS) program aggregates observations from over 100,000 volunteer-operated stations around the world, including many Raspberry Pi stations.

On a larger scale, Raspberry Pi weather stations have also been deployed as part of environmental monitoring initiatives. For instance, the government of Seychelles installed 19 automated weather stations across the island country's outer islands and remote areas using Raspberry Pis and open-source software. The high frequency, location-specific data helps scientists and policymakers in Seychelles better understand and prepare for climate impacts.

As climate change brings more extreme weather events, distributed networks of hyperlocal weather monitoring are growing increasingly important for resilience planning, disaster response and community preparedness purposes. The low-cost yet powerful Raspberry Pi has opened up new possibilities for weather and climate data collection around the world.

Energy Monitoring and Conservation

Monitoring and conserving energy is another critical area where Raspberry Pis are making an impact. By reading electricity, gas and water meters, Raspberry Pi-powered devices can help households, businesses and municipalities pinpoint ways to reduce resource consumption and greenhouse gas emissions. There are many open-source projects that enable detailed energy monitoring with just a Raspberry Pi and low-cost sensors.

A popular example is the RPi-Energy-Monitor created by Switch Doc Labs, which uses a current sensor clamp and Raspberry Pi 3B+ to log real-time and historical power consumption data from home or office circuits. Users can wire sensors to individual plugs or whole-home circuit breaker panels to track appliance-level or aggregated building-wide electricity usage. Paired with web or smartphone apps, the system provides energy consumption visualizations to promote more efficient behaviors.

At larger scales, Raspberry Pis have been adopted for city-wide smart meter infrastructure and industrial energy management systems. For example, the city of Turku, Finland deployed over 60,000 smart electricity meters across the municipality that use Raspberry Pis to transmit near real-time consumption data via LTE networks. This empowers residents to monitor and reduce their electricity use, while also supporting demand response programs.

Various colleges, companies and factories have also incorporated Raspberry Pi energy monitoring into sustainability initiatives. For instance, Carnegie Mellon University installed Raspberry Pi meters in 130 campus buildings to analyze energy usage patterns and optimize operations. A bread manufacturing plant in Mexico integrated Raspberry Pi dataloggers throughout its facility to gain insights into production line electricity consumption.

Beyond monitoring, Raspberry Pis are playing a role in automating renewable energy and microgrid systems as well.
