Abstract
The search to reduce the disappearance of infants has been the main objective of many public officials and institutions, however, the result has not been satisfactory yet. Our country is considered one of the most dangerous regarding citizen insecurity; The state of Puebla ranks third in the nation in terms of missing minors, in Huauchinango there are at least 50 missing so far in 2020, half of whom are minors. This work shows the design and development of a double alarm prototype for possible kidnappings and loss of infants in a place that agglomerates people focused on the Huauchinango region, with the main objective of helping to reduce the theft of infants, kidnapping or loss, following a simple and straightforward process method using two devices, emitter and receiver. The process is between two Squeaky bracelets which are linked to each other, they will have indicator lights when the link is in the programmed range (green indicator), if it is outside the range the red light will be activated and it will emit a sound, to give notice of possible distancing between devices. The project is not only for the reach of infants, but to the entire public.
