The Blues Wireless Notecard includes onboard temperature and accelerometer sensors that are accessible via the Notecard API. Temperature and voltage is captured every 5 minutes, and reported with the JSON included in every sync operation. Shock/impact detection can be reported by enabling the built-in IMU sensor (card.motion API), then querying it to enhance your data with “shock/impact” information. In addition, cellular signal strength data is included with the card.wireless API.
