SENSOR DEVICE

To provide a sensor device that can improve a detection accuracy of an environmental sensor.SOLUTION: In a sensor device 10 attached to a rear portion of a helmet, a through hole H1 for an environmental sensor is provided on a left surface SL of a housing. A through hole H2 for a buzzer is provided on a lower surface SD of the housing. A distance between an environmental sensor 20 and the left surface of the housing is shorter than a distance between the environmental sensor and a right surface SR of the housing. In a case where the through hole for the environmental sensor is provided on the right surface of the housing, a distance between the environmental sensor and the right surface of the housing is shorter than a distance between the environmental sensor and the left surface of the housing. A distance between the buzzer and the lower surface of the housing is shorter than a distance between the buzzer and an upper surface of the housing.SELECTED DRAWING: Figure 2 【課題】環境センサの検知精度の向上を図ることができるセンサ装置を提供する。【解決手段】ヘルメットの後部に取り付けられるセンサ装置１０において、筐体左面ＳＬには、環境センサ用貫通孔Ｈ１が設けられている。筐体下面ＳＤには、ブザー用貫通孔Ｈ２が設けられている。環境センサ２０と筐体左面との距離は、環境センサと筐体右面ＳＲとの距離より短い。筐体右面に環境センサ用貫通孔が設けられている場合には、環境センサと筐体右面との距離は、環境センサと筐体左面との距離より短い。ブザーと筐体下面との距離は、ブザーと筐体上面との距離より短い。【選択図】図２
