Abstract
To collect data, an electronic device transmits a signal on an output channel of the headset jack to provide an excitation signal to a sensor for measuring a physical quantity. A signal from the sensor is received via an input channel of the headset jack of the electronic device. Data based on the received signal may be sent from the electronic device to a remote location for further processing. The data may be used to detect a physical condition, e.g., a temperature, humidity, soil moisture, sound, vibration, pressure, motion, and/or pollutants.
