ABSTRACT:
An animal monitoring system includes a temperature monitoring unit which is governed by a microcontroller, i.e., an electronic computer, and which is placed inside an animal's body, usually inside the birth canal. An inactive or sleep mode of the monitoring unit reduces battery drain. Periodically the monitoring unit enters an active mode during which a temperature of the surroundings is measured; the analog temperature is converted to digital data, then transmitted as an UHF, low-power radio signal via a self-contained antenna. A base unit receives the signal, displays the received temperature value, compares the received temperature value to a predetermined range of temperature values, and initiates an alarm condition if the received temperature is outside the predetermined range. The alarm condition also results if the animal strays and the signal is lost. The alarm condition includes an audible and/or visual alarm, either at the base unit or at a remote location, and may include dialing preselected telephone numbers and transmitting a prerecorded message when such an automatically dialed call is answered.
