MH-BPS101 is a compact EMG/ECG sensor, designed for registration and measurement body biopotentials, such as an electromyogram and an electrocardiogram.

Very easy to use with such microcontrollers as Arduino, STM32 and Teensy. To receive a signal, it is enough to power the device with a voltage of 3.3V (no more than 5.5V) and connect the output signal to a microcontroller input.

We provide free libraries for using MH-BPS101 sensor with Arduino, Teensy and STM32, also we provide sketches for visualisation signals by Python and Matlab.

Features:

• Size: 6.8x32.1 mm.
• Supply voltage range 3.3 - 5.5 V. Typical voltage 3.3 V.
• Gain is 1000 V/V.
• 8 – 200 Hz filter.
• Dry skin contact.
• Stainless steel electrodes.
• Libraries for Arduino, STM32 and Teensy.
• Examples of sketches for signal visualisation by Python and Matlab.

NOTE: this product is NOT a medical device and should not be used to diagnose or treat medical conditions.

If you plan to use the sensor with a plugged-in PC (connected to the household power supply), we recommend purchasing a USB Isolator: it will reduce the interference caused by the household power supply and also make the connection safe.
