The present invention relates to an object sensing notification safety helmet, sensing an object by an ultrasonic sensor and ringing a piezo buzzer to notify a wearer of the fact. The object sensing notification safety helmet reduces a blind spot for a wearer to avoid a collision in advance. First of all, two ultrasonic sensors (1, 2) are attached to a head band (4) back and forth. At this time, a fabric ring is made on the head band and the ultrasonic sensors are attached thereon to allow the ultrasonic sensors to be moved inside the head band. An arduino substrate (3) is installed in the center, and the piezo buzzer (5) is hidden in a side surface. |
