MH-BPS102 is a compact EMG/ECG sensor, designed for registration and measurement body biopotentials, such as an electromyogram and an electrocardiogram.
Adjustable signal gain.

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-BPS102 sensor with Arduino, Teensy and STM32, also we provide sketches for visualisation signals by Python and Matlab.

Features:

• Size: 19.1x14.9х3.0 mm (accuracy to 0.2 mm).
• Operate voltage range is 3.3 – 5.5 V. Typical 3.3 V.
• The output signal is analog, the maximum range is equal to the supply voltage.
• Base gain is 500 V/V, can be increased by 8 additional Gain Selections: ⨯1, ⨯2, ⨯4, ⨯5, ⨯8, ⨯10, ⨯16 or ⨯32 V/V
• Serial Peripheral Interface (SPI) gain selection.
• 8 – 200 Hz filter.
• Dry skin contact.
• Stainless steel electrodes
• Built-in LED for indication (supply voltage 3.3 - 5.5 V

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

See the pdf-file below for more information on the features and connection of the sensor. English version will be here soon.

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.
