SPOTWeb and Sensor.Network

From Vipul Gupta’s Weblog:

Sun SPOTs are tiny, battery-powered, wireless computers that can be programmed in Java. Different types of sensors (e.g. GPS, temperature, humidity, proximity, light) and actuators (e.g. servos, motors) can be attached to these devices for use in a wide range of applications.┬áThis blog entry discusses two web-based services – SPOTWeb and Sensor.Network – for interacting with these devices and collecting, analyzing and visualizing data from attached sensors.

The SPOTWeb service lets remote users interact with a network of SPOTs using a standard browser. Authorized users can monitor the state of sensors, applications and other system statistics. They can also install, start, pause, resume, stop and remove applications. In the following video, I walk you through many of these features (I recommend the HD-version in full-screen mode to minimize the blurriness of on-screen text). You can follow along on your own by downloading the latest SPOT SDK (red-090706 at the time of this writing) from and running SPOTWebDemo (it is one of the new demos bundled with the red release).

Sensor.Network is a web-based service for sharing, visualizing and analyzing sensor data collected from a variety of sources, e.g. mobile phones, automobiles, datacenters or embedded devices like the Sun SPOT. Besides supporting a heterogenous mix of data sources, the service supports multiple sensor installations, each of which could potentially be owned by a different entity. It places a strong emphasis on security and privacy concerns and gives researchers and scientists fine-grained control over how their data is shared with authorized partners. Additional details are available in this article. The service is still under development but the following video filmed during JavaOne 2009 provides a good overview of the currently available functionality.
