There are many ways to remind your child of the dangers. Flashes and sirens can attract children, which puts children at risk. In contrast, the irritating odor tube is used more.
Safe Smeller has two parts: a sensing module on children's cloth and an odor generator attached on any dangerous objects. When the child is too close to the dangerous objects, the sensing module will send signal to the odor generator and activate it. The irritating odor released by the odor generator will force the child to leave and arouse parents'attention, so as to prevent the occurrence of potential accidents.
