The expectations of both experienced DIY enthusiasts and beginners are increasing. We are aware that advanced technology is developing so rapidly that we can use really smart solutions. At the same time, we require that the systems are easy to install and that their use does not require a lot of specialist knowledge. Gravity systems perfectly match this trend and therefore attract so much interest. These open-source electronic modules show compatibility with both Raspberry Pi and Arduino. Gravity has many advantages, including, among others, great possibilities of project development. Installation is quick and easy, does not require a lot of experience, so even a beginning do-it-yourselfer can handle it. You have a chance to dynamically develop your projects, complementing them with additional functionalities. You can quickly and flawlessly connect the modules with each other via a plug-and-play interface and color-coded output markings. Moreover, there is no need to use a soldering iron during installation, which also supports efficient installation. You fear that you will make a mistake during the installation and connect the connector the other way around. If this happens, there is no risk of damaging the module. Thus, you can learn how to create and design electronic devices on Gravity without any fun. This is a very good choice for beginners who are just starting their adventure with electronics. Develop yourself and carry out more and more difficult and complex projects.
Using Gravity modules - what can be created using them...
Gravity modules are available in many variants. They are solutions with a very versatile application, a wide range of possibilities and at the same time easy installation and use. In our shop's offer you will find a few interesting proposals, thanks to which you will be able to carry out a project for, among others, an extensive weather station, which will monitor environmental conditions outside. You will receive from it information concerning not only temperature, but also air humidity. Moreover, you can design a station monitoring conditions in other environments and examining other parameters such as: salinity, gas pressure, sound pressure, pH, liquid level and light intensity. An interesting solution for those who want a strong experience is the Lightning Sensor, which is used to detect lightning at a distance of up to 40 km.
At the beginning, we recommend mainly Gravity DFR001 set. It is equipped with 9 different sensor modules and connecting cables. You get a ready-made set, allowing you to install it immediately and use it quickly. You don't need any additional accessories, you just need basic knowledge in the field of electronics, which every beginner DIY enthusiast is sure to have.
