Easy data logging with grove sensors using the MKR Connector Carrier and MKR boards
If you’re looking for an ever faster, smoother, and more rewarding way to build your own IoT projects at home, the new MKR IoT Carrier Rev2 could be perfect for you. The new carrier can work with any board from the MKR family, giving you a wide choice of connectivity options to match the needs of your next IoT project. The MKR IoT Carrier Rev2 doesn't require any additional components to get started, and you can create impressive and complete hassle-free projects this way. What does the carrier include? You’ll get all the sensors and actuators you need to develop IoT projects and connect them to the internet, taking your home automation journey to the next level. Let’s take a quick look at what you can build with the MKR IoT Carrier Rev2 and any board from the MKR family. Environment monitoring stations. The new carrier comes with sensors that allow you to map and measure various things in the world around you — temperature, humidity, air quality, barometric pressure, and more. You can also track the movement of the board. For even more sensory awareness, you can connect analog or I2C grove compatible modules to the grove connectors. You can store the data you collect in the SD card or send it directly to the Arduino IoT Cloud. GUI IoT interface. Visualizing your data is incredibly important — and the Rev2 comes with its own OLED color display, allowing you to create your own navigation menus. You can also use the included LEDs and buzzer for feedback. Connect to and control external devices. The IoT is all about networks, and with the Rev2 you can control electronic devices up to 24 Volts using the two on-board relays. You can do this manually — like switching your reading lamp on or off via the Arduino IoT Cloud Remote app, or you can set the lamp to behave according to sensor data like the light levels in the room. The MKR IoT Carrier vs the MKR IoT Carrier Rev2 — what’s the difference? There are a few key differences
