Abstract: An apparatus for checking and monitoring a child's temperature through the use of a baby pacifier. The pacifier provides a radio signal to a receiver unit. The pacifier senses the temperature and provides a proportional frequency signal if above or below designed limits. The pacifier detects temperature variation, discriminates between normal or abnormal temperatures and automatically transmits only the abnormal high/low temperature signals to a remote radio receiving apparatus where such signals are visually displayed and audible/visual alarms are provided.
