Good accuracy, documentation could be better

The sensor data is quite accurate when compared to clinical devices. However, the setup guide for the gyroscope calibration was a bit sparse. Once figured out, it works perfectly for my motion analysis project.

Perfect for custom wearables

I built a custom wristband for tracking stress levels during workouts. The combination of SpO2 and skin conductance gives a great overview of physiological state. Highly recommended.

Excellent for DIY Biofeedback Projects

This module is incredibly versatile. The GSR readings are stable, and integrating the accelerometer data with heart rate metrics was straightforward using the provided libraries. Great value for researchers and hobbyists.

Reliable data output

We use these in our university lab for student projects. The consistency of the pulse and GSR data is impressive for the price point. No connectivity issues so far.

Exceeded expectations

The 3-axis gyro adds a whole new dimension to the data logging. Being able to correlate movement spikes with heart rate variability is exactly what I needed. Fast shipping too.

Great hardware, easy integration

Connected easily to my ESP32. The I2C interface is clean and the data stream is consistent. Took off one star because the wristband strap material feels a bit cheap, but the electronics are top-notch.

5 FAQ

Q: Is this module compatible with Arduino Uno?

A: Yes, the module supports I2C and UART interfaces which are fully compatible with Arduino Uno. You will need to connect the VCC, GND, SDA, and SCL pins accordingly.

Q: What is the battery life if used continuously?

A: Battery life depends on the external power source you connect, as this module does not include an internal battery. When powered by a standard 500mAh LiPo battery, continuous operation typically lasts 6-8 hours depending on sampling frequency.

Q: Can I access the raw data from the gyroscope and accelerometer simultaneously?

A: Absolutely. The firmware allows simultaneous reading of all sensor channels. You can retrieve raw 3-axis acceleration, angular velocity, heart rate, and GSR data in a single polling cycle.

Q: Does this require external calibration for the GSR sensor?

A: The module comes pre-calibrated for general use. However, for precise scientific applications, we recommend performing a baseline calibration specific to the user's skin type before starting data collection.

Q: Is the wristband size adjustable for children?

A: The included strap has multiple adjustment holes and fits most adult wrists. For children, you may need to purchase a smaller replacement strap separately, though the sensor module itself is lightweight and suitable for smaller arms.
