    Abstract: An electronic device may include one or more low-noise pressure sensors for measuring air pressure. The electronic device may include wireless communications circuitry for communicating with external devices also having pressure sensors. Pressure data gathered by an external device may be used as reference pressure data for the electronic device. For example, if both devices are located in the same building, both pressure sensors will detect similar pressure fluctuations due to doors opening and closing and temperature-control systems turning on and off. By subtracting the reference pressure data from the pressure data gathered by the electronic device, calibrated pressure data may be obtained and may be used to reliably detect vertical displacement changes of the electronic device. In other scenarios, the pressure data may be compared with the reference pressure data to determine whether the two devices are in the same room.

    Abstract: An electronic device may be provided with proximity sensor capabilities for monitoring for the presence of nearby external objects. The electronic device may make temperature measurements such as measurements involving the monitoring of nearby objects for emitted blackbody light indicative of whether or not the external object is a heat-emitting object such as a human body part. The same sensor that is used in gathering temperature readings may be used in gathering proximity sensor data or separate temperature sensor and proximity sensor detector structures may be used. Motion sensor capabilities may be provided using sensor structures having an array of heat sensing elements. Signals from the array of heat sensing elements may be used in making temperature measurements and in gathering proximity sensor readings. Sensor structures may operate at wavelengths longer than 3 microns such as wavelengths from 3-5 microns or 10-15 microns.

    Abstract: An electronic device may be provided with electronic components such as buttons and environmental sensors. An environmental sensor may be temperature sensor for gathering temperature data associated with the environment surrounding the device. The temperature sensor may be mounted to a button member for the button. The button member may be an actuating member that moves within an opening in a device housing and that extends beyond an outer surface of the housing into the surrounding environment. The button member may be arranged so that an internal electronic switch is activated when the button member is moved within the opening. The button member may be thermally isolated from other device structures using insulating material on the button member. The button member may be formed from a thermally conductive material that transmits the temperature of environmental materials that contact the button member to the temperature sensor.
