Disclosed is a device for detecting temperatures which differ from a variable norm of particular use in detecting elevated temperatures in cattle. The device, one being attached to each animal, includes a square wave generator, an identification number encoder for outputting the identification number of the particular animal in the herd, a fever detector with an ambient temperature compensating circuit which provides output only when internal temperature of the animal is above a preset value for a given ambient temperature, and a transmitter which sends the identification code to a receiver. In certain embodiments, no separate fever detector is provided; rather the square wave generator outputs a frequency-modulated signal related to the internal body temperature. Of particular interest is the identification number encoder which intermittently outputs a preset hardwired identification code to the transmitter at periodic intervals for transmission to a receiver either at constant intervals or when temperatures sensed by a temperature detector exceed the variable norm by a preset given amount.
