Projects
Since it also includes a Core Module equipped with a 3-axis accelerometer and digital thermometer, the kit can be used for various other projects. The basic projects are available on the web.
HARDWARIO Playground
The kit includes the HARDWARIO Playground app, which can be downloaded for Windows, macOS and Linux computers. With the application, you connect the assembled devices to the created radio network, set the purpose of each device according to the selected firmware, and add the required functions using the Node-RED application. The open-source kit passes its data over MQTT, so you can process it further in Node-RED, InfluxDB and Grafana, for example. Introducing HARDWARIO Playground

Safety information
- Read the documentation at docs.hardwario.com before installing the product.
- Use the product only for its intended use and within the operating conditions given in its documentation.
- Do not modify the product beyond what the documentation describes. Do not use a visibly damaged product.
- The product is not designed for potentially explosive atmospheres.
- The modules are electronic assemblies sensitive to electrostatic discharge: hold them by the edges and touch a grounded object first.
- Power them only as described in the documentation (USB, a battery module or the Power Module).
- Keep small parts out of the reach of small children.
- Replace the batteries only with the type given in the documentation and insert them with the correct polarity (+ and −).
- Never recharge primary (non-rechargeable) cells. Do not short-circuit, open, crush or heat batteries and do not throw them into fire.
- Keep batteries out of the reach of children.
- A damaged or leaking battery can overheat or catch fire: take it out of service and do not touch leaking electrolyte.
