TDK SmartBug™ (MD-42688-P) is an all-in-one sensor module which provides the perfect out-of-box IoT solution, as it requires no soldering, programming or any other mechanical changes. It is a pre-programmed module that facilitates quick access to meaningful data from its motion, pressure, ultrasonic ToF, temperature, humidity, and MEMS magnetic-field sensors.

Each IoT application today requires trusted and intelligent sensor data for making critical product development decisions. SmartBug meets this key requirement by leveraging data from its high-performance sensors and algorithms. Additionally, SmartBug’s Wi-Fi (TCP-IP) interface on its Add-On board expands the module’s overall wireless data streaming and logging capabilities to higher throughput and longer ranges. The SD card slot allows autonomous data logging for applications that require larger amounts of reliable data to derive real value.

The TDK SmartBug Add-On board is used to enable extra functionality on the SmartBug module. The Add-On board consists of a Wi-Fi chip, an SD card slot and an ultrasonic range sensor from TDK.

All data and outputs from the module can be visualized, streamed and recorded on the SmartBug Windows 10 Application. Windows 10 provides a secure, familiar and powerful ecosystem, with which users can collect and analyze data from SmartBug.
