Wearable ECG and Heart Monitor Evaluation and Development Platform
The MAX-ECG-MONITOR evaluation and development platform, featuring the MAX30003 clinical-grade AFE, analyzes data and accurately tracks heart signals (ECG and heart rate), as well as user status signals such as temperature and motion, to provide valuable insight for clinical and fitness applications. Quickly develop ECG-based applications with the embedded algorithms, or use it to collect raw data to develop your own custom health sensor algorithms. Part of the Movesense ecosystem, the MAX-ECG-MONITOR runs an open Application Program Interface (API) for developing unique in-device apps for a variety of ECG-based use cases showing heart-rate signals at rest or during high motion activity.
The MAX-ECG-MONITOR works with an Android® OS device to display real-time measurements of each of the sensors. It also captures the measured raw data from the health sensor signals and stores them to allow full access for custom development of use case results and summaries.
The MAX-ECG-MONITOR comes with an ECG/heart-rate monitor reference design module with embedded firmware, chest strap and dry electrodes for fitness applications, and wet electrodes for clinical applications. It includes instructions for downloading the Android-based application.

Quick Start Guide for the MAX-ECG-MONITOR
What You Need
- Chest strap or adhesive electrodes (both provided)
- Android® device (e.g., phone, tablet, etc.) with Bluetooth connection for data logging
The MAX-ECG-MONITOR turns on automatically when it detects a heartbeat through the electrodes. A red LED flashes on the top of the monitor to indicate that it is on.
The monitor automatically powers off when no heartbeat is detected across the electrodes (for example, when the device is not worn).
Wearing the ECG Monitor
- Snap the monitor into the chest strap connector.
- Moisten the strap electrode areas with water or electrode gel.
- Adjust the strap length to fit tightly but comfortably around your chest below the chest muscles with the Maxim logo facing out.
- Ensure the moist electrode areas are firmly pressed against your skin
- For applications where more secured mounting is desired, use the adhesive electrodes (red) instead of the chest strap. NOTE: Detach the monitor and rinse the chest strap under running water after every use. Dry the strap and electrodes. Sweat and moisture left on the electrodes can keep the device on unnecessarily and reduce battery life.
NOTE: The adhesive electrodes are for single-time use and may be left on the skin up to a few days. More supplies can be ordered from www.maximintegrated.com.
Movesense® Showcase App
The ECG monitor can be paired with an Android-based device, such as phone or tablet, for viewing and logging data through the Movesense Showcase app for Android.
Installing the App
- Save the provided .apk-file to a location that you can access by phone (for example, to the phone's storage if you have a file browser or to Dropbox®).
- Open the file, which prompts you to install the Movesense Showcase app. The main screen of the app is shown below.
Figure 1. Movesense Showcase main screen.
Connecting to an ECG Monitor
- To connect the MoveSense app to an ECG monitor, press the Movesense icon in the app—devices available for Bluetooth® connection are then displayed (see figure below).
Figure 2. ECG monitors available for connection.
- Click on the appropriate monitor to connect. The connection can take 10 seconds to 30 seconds to establish.
Using the App
After a successful connection, a list appears to show all the measurement applications that are available.
- Scroll down the screen to reveal a complete list (see figures below, result split in two images).
Figure 3. List of sensors.
- Select the desired measurement application.
For example, click on the ECG item to bring up the ECG measurement screen (see figure below).
Figure 4. Inactive ECG measurement application.
- Activate the measurement application by sliding the Subscribe button to the right.
In this example, the button becomes blue and the ECG chart is displayed at the bottom of the screen (see figure below). Data is logged into a file called *_EcgActivityGraphView.csv in the local MoveSense folder.

Other measurements include heart rate, temperature, and motion sensing. Refer to the "Maxim ECG Monitor User's Guide" for a complete description of each available measurement.
The monitor uses a 3V lithium cell battery (CR 2025). Refer to the user's manual for instructions to replace the battery.
