These environmental sensors for Nissha can measure motion, temperature/humidity and open/close. Based on the sensor data, it can be used to understand the environment of the office and other places to create a more comfortable environment. When considering the ideal shape of the environmental sensor, a shape that follows the rules of the horizontal and vertical space as much as possible seemed to be optimal. We spent a lot of time designing a simple box shape, from the way it is mounted to the way its internal structure appears. In addition, the height of the box is fixed at 80 millimeters so that the various sensors can be neatly arranged in a series of horizontal tiles.
