Sit reminding device for a long time

The utility model discloses a sit reminding device for a long time, including treater, micro motor, distance measuring sensor, the optical emitter, treater electric connection micro motor, distance measuring sensor, the optical emitter, characterized in that, distance measuring sensor is located the shell upper end, the optical emitter is located shell front portion, angle downward sloping, micromotor takes dynamic testing rotatory apart from the sensor rule, drives the random motion of optical emitter. This device utilizes rotatory distance measuring sensor to detect user's scope, prevents the simple test error of bringing that moves of user, reminds the user through in disorder laser, disturbs the effectual while not lead to the fact the influence to other people. 本实用新型公开了种久坐提醒装置，包括处理器、微型电机、测距传感器，光发射器，所述处理器电性连接微型电机、测距传感器，光发射器，其特征为，所述测距传感器位于外壳上端，所述光发射器位于外壳前部，角度向下倾斜；所述微型电机带动测距传感器规则旋转，带动光发射器无规则运动。本装置利用旋转的测距传感器检测用户范围，防止用户简单移动带来的测试误差，通过凌乱的激光提醒用户，干扰效果好同时对他人不造成影响。
