The latest version of OpenSensorHub now gives fine-grained control over user permissions and other security options.
In addition to better support for HTTPS (SSL) and several authentication methods (HTTP Basic, HTTP Digest, X509 Certificate, OAuth) through simple configuration in the web admin interface, a hierarchy of permissions can now be defined by each OSH module needing some kind of access control. These permissions can then be assigned to users and roles using the security API.

Using a combination of the OpenSensorHub (OSH) Arduino helper classes (https://github.com/opensensorhub/osh-arduino) and the Adafruit Unified Sensor Library ( https://github.com/adafruit/Adafruit_Sensor ), it is straightforward to develop drivers to enable all supported Arduino sensors to register with OSH SOS-T. Most took no more than 10-15 minutes to add.
When properly configured, these Arduino sensors can push observations to an OSH node over WiFi using the transactional components of an SOS service (SOS-T). Then all of the power of OSH is available, including storage, processing, and serving of the data through standard web or IoT interfaces.
To use supported Arduino sensors for OSH, one would:
- The SOS-T server which will receive the data, is referenced in the sketch within the newSOSClient method call. e.g. sos = new SOSClient(client, “192.168.0.25“, 8181, “/sensorhub/sos“);
- flash the Arduino “sketch” file for the appropriate sensor onto the board
- restart the Arduino board; it will then register with OSH and send observations until you power it off

The Vaisala Weather Transmitter WXT520 is an advanced and highly-configurable system of weather sensors all in a single package. Because of its compact size, this weather transmitter is well-suited for dynamic field deployment as well as more permanent deployment, making it ideal for integration into the SensorWeb.

We require a suite of inexpensive, geospatially-aware, video cameras that could run OpenSensorHub (OSH) onboard and store and/or stream in real time, video and navigation data (i.e. location and orientation). The OSH team thus developed the GeoCam based on Raspberry Pi (RPi) using the RPi HD video camera, an Adafruit GPS (with or without antenna), and an Adafruit orientation sensor. (Build your own GeoCams following the recipe here).

Unless you have been living under a rock, you have probably seen that Internet of Things (IoT) is all aflutter. Everyone and his brother are connecting THINGS to the Internet, and connecting things to each other via the Internet! Some of these things are sensors. Some of them are actuators. Some of them are processes. Others are combinations of these three, which together some call robots. It is all very cool. But, it has a long way to go.
