Multifunction sensors and transducers incorporate two or more individual sensors with driving and output conditioning circuitry. The data is communicated via a single output type such as Bluetooth, USB, CAN bus, Ethernet, I2C, SPI, or RS-485. Combination examples include accelerometer-magnetometer, humidity-pressure-temperature, humidity-light-pressure-sound-temperature-tilt-vibration, and accelerometer-gyroscope.
