1. An external infusion device for infusing fluid into a person from a reservoir, comprising:
- a housing adapted to be carried by on an exterior of the person;
a drive mechanism contained in the housing and operatively coupled to the reservoir to deliver fluid from the reservoir into the person'"'"'s body;
a processor contained in the housing;
a memory coupled to the processor and adapted to store a predetermined temperature threshold; and
a thermal sensor coupled to the processor and adapted to provide a temperature output signal as a function of temperature in the housing;
wherein the processor is adapted to compare the temperature output signal with the predetermined temperature threshold, and to control the infusion device based on the temperature comparison.

Abstract
An ambulatory medical device for detecting acceleration, temperature, and/or humidity conditions in or around the medical device is provided. The medical device includes one or more acceleration, thermal, and/or humidity sensors which detect acceleration, temperature, and/or humidity conditions in or around the medical device. In response to detected conditions, the medical device may, among other things, alter the operation of the device, provide an alarm or warning to the user, or transmit data about the detected conditions to another device.
