Uzuki Sensor Shield


Uzuki - IoT Sensor Shield for Konashi & Arduino, is a shield board developd by Macnica to connect through I2C with Yukai Engineering's physical computing tool kit "Konashi." In addition to Konashi, Uzuki also connects to Arduino through I2C.

Uzuki has on-board 3-axis accelerometer, temperature & humidity sensor, proximity & UV index sensor. These sensors enable the use of data such as ambient temperature, humidity, light luminescence, IR level, UV level, vibration, shock, and detection of movement on the iOS devices using Konashi environment. The grove connector can connect off-the-shelf I2C sensors.

The Konashi environment enable software engineers, designers and artists to prototype easily without the need to access complex hardware and develop firmware on the MCU.

Connecting Uzuki to Konashi module as a sensor shield, you can easily develop various sensor data acquisition application without soldering.
