ABSTRACT:
A remote timer, thermometer and paging system includes a first unit having a radio frequency transmitter, a housing having a recess formed therein and a timer for selecting a time period. The system includes a temperature sensor in communication with the first unit for measuring temperature. The system also includes a second unit having a radio frequency receiver adapted to communicate with the radio frequency transmitter of the first unit. The first unit is adapted to wirelessly transmit an alert signal to the second unit when the temperature measured by the temperature sensor matches a pre-selected temperature or when the selected time period has expired. The second unit is insertible into the recess for storage inside the first unit and is removable from the first unit for moving the second unit to a remote location away from the first unit. The first unit includes a controller that deactivates the radio frequency transmitter when the second unit is at least partially inserted into the recess and activates the radio frequency transmitter when the second unit is removed from the recess so as to provide for wireless communication between the first and second units.
