MicroECG

Overview

MicroECG is an ECG monitoring module based on nRF51822 BLE chip and BL1860 ECG chip, which can transport heart information through either UART or BLE. Users can control nRF51822 via AT Commands. Also, they can use the open-source software to develop their own firmware, making it to support more functions.

The heart information includes row data and the heart rate. The row data is the result of ADC detection, representing the strength of heart beat. The row data can be used to draw ECG directly. And the heart rate is the result of calculation with the row data.

This ECG module is easy to use. Data can be transported through either UART or BLE. When the switch on the board is set to the BLE side, data can be transported through BLE. In this case, one can use app on one’s phone to receive the heart rate from this module. When the switch on the board is set to the UART side, data can be transported through UART. In this case, one can control the board with some AT commands.

You may order the ECG lead wire and ECG limb clamp to use with the MicroECG module.  How to use it? Solder your MicroECG to the board you want, plug the lead wire into the ECG module, then buckle the red clamp with the red wire, buckle the black clamp with the black wire, and buckle the white wire with another desired clamp. The black one should clamp with your left arm, while the red and white one should clamp with your right arm.

If you prefer a completed board that doesn't need any soldering, please order BL18 ECG Maven module.
