The GrovePi Shield is an open source platform to connect a range of sensors called the Grove sensors to the Raspberry Pi. We can create our own Internet of Things applications without any need for soldering using the GrovePi! Grove is an easy-to-use collection of more than a hundred Plug and Play modules that we can use to sense and interact with the physical world. The array of sensors include relays, temperature sensors, OLED displays, ultrasonic ranger, joystick, accelerometer, humidity sensor, GPS, and so on. They are divided on the basis of the following six categories: Environment Monitoring, Motion Sensing, User Interface, Physical Monitoring, Logic Gate, and Power.
You can interact and monitor the world using the sensors and then store the data on your Raspberry Pi bridging the gap to the real world!
As you can see from the preceding image, the GrovePi slips over the Raspberry Pi and has a variety of sockets to hold the different sensors that you might want...
