Source: TDKThe all-in-one sensor module integrates a six-axis inertial measurement unit (IMU) with magnetometer, pressure, temperature, humidity and ultrasonic sensors as well as precision algorithms such as HVAC filter monitoring, asset monitoring, gesture detection, activity classification, air mouse monitoring and smart door open/close detection.
SmartBug allows for remote monitoring of both Bluetooth low energy (BLE), Wi-Fi and autonomous SD card data logging for IoT applications with large data volumes. The module includes an ecosystem of components to enable features:
- Nordic Semiconductor — A low-power MCU with BLE 5.2 multi-sensor data from the SmartBug that runs algorithms as well as support for add-on cards with SD card logging and ultrasonic sensors.
- Espressif Systems — A Wi-Fi chip that expands the wireless data streaming and logging capabilities of the SmartBug.
- AKM — A magnetometer that includes compass data collection, nine-axis sensor fusion for orientation heading and magnetic anomaly detection for asset monitoring applications.
- Sensirion — Humidity and temperature sensors for data streaming and logging of SmartBug to higher throughput (up to 2 KHz) and longer ranges.
IoT applications that the SmartBug could be used for include wearables, hearables, robotics, smart door lock detection, asset monitoring, HVAC filter monitoring, air mouse, robotic vacuums, orientation detection, smart home and smart appliances.
