SmartBug™: The All-in-One Sensor & Algorithm Module for Your IoT Applications

Written by Mike Benson

August 28, 2020

TDK SmartBug (MD-42688-P) is a multi-sensor wireless module that leverages TDK’s MEMS sensors and algorithms for a wide range of IoT applications.

This module combines six sensors, a powerful wireless (BLE) MCU, seven algorithm driven features and a rechargeable battery, in a small enclosure. It also comes with the option of an Add-On board that includes a WiFi module, an SD card slot and an ultrasonic sensor from TDK.

It is the go-to-module for quick and easy access to reliable and smart sensor data. The data from each sensor and algorithm can be accessed “Out-of-Box” without the need for any programming, soldering or extra modifications. This makes it a perfect enabler for IoT product developers, algorithm developers and sensor data enthusiasts to better understand real application signatures, environment variations and multi-sensor/algorithm behaviors.

It includes ICM-42688-P 6-axis IMU, ICP-10100 pressure sensor with humidity sensor, temperature sensor, magnetic sensor and an optional CH-101 ultrasonic sensor from TDK, creating an All-in-one sensor solution. A unique feature of this module is the provision of smart sensor data from IoT sensor algorithms with customized tuning parameters. The algorithms include Door Open/Close Detect, 6 and 9-axis sensor fusion, Asset Monitoring, HVAC Filter Monitoring, Pedometer, Activity classification, Gestures and Air Mouse Monitoring.

The SmartBug data and outputs can be easily visualized, streamed and recorded on a Windows 10 Application – SmartBug. This application is available for free to download on the Microsoft Store. The application offers great flexibility to acquire data from BLE, WiFi or USB, depending on the use-case. SD card logging feature in addition allows autonomous logging of data (upto 32GB) without any Windows 10 Application.

Key Features:

  • All-In-One Sensor Module including a combination of sensors and algorithms
  • Out-of-Box Solution
  • Pre-programmed. No soldering or programming needed.
  • Dedicated source of raw and intelligent sensor data
  • Small size lets you stick this module almost anywhere
  • BLE, USB, WiFi and SD data logging
  • Reliable and quality data from highperformance sensors and algorithms
  • Over the Air (OTA) Firmware upgrade
  • Visualization Software available
  • Optional Add-On Board adds WiFi, SD card and an ultrasonic range sensor

SMART APPLICATIONS
