Scheme introduction:
Note: The design scheme of ECG module is sold here, including: ECG module schematic diagram, MCU program code, Bluetooth chip program code, and mobile phone ECG data processing software APK.
If you need ECG module PCB and ECG data processing program code (APK code), please contact again.
Mini ECG is a high-performance, low-power single lead ECG monitoring module with Bluetooth interface and TF card interface. ECG data can be transmitted to the mobile phone's ECG data processing software through Bluetooth, or saved to the local TF card. It can be directly used for ECG monitoring or secondary development.
Technical indicators of circuit board:
Ø Common mode rejection ratio of signal input end: 80 dB (DC to 60 Hz).
Ø Fast recovery function reduces filter setup time.
Ø Automatic detection of lead falling off.
Ø HBM ESD (anti human electrostatic discharge) rating: 8kV.
Ø Input impedance 10 | | 7.5 G Ω | | pF.
Ø Input voltage noise (RTI) peak to peak voltage noise (f=0.5 Hz to 40 Hz) 14 μ V p-p.
Ø Filter design: dual pole high pass filter with cut-off frequency of 0.3 Hz and a dual pole low pass filter with cut-off frequency of 37 Hz.
Ø 24 bit high precision Σ-Δ Type ADC.
Ø Low power Bluetooth chip BLE, receiver sensitivity: - 93 dBm.
Ø Mobile phones can monitor and process ECG signals through Bluetooth.
Ø Rechargeable battery power supply (3.7V, 400mAh), continuous ECG monitoring for 24 hours.
Ø Charging voltage 4.35V~6V, charging through MiniUSB interface.
ØØØØØØØØ has a charging indicator light. When charging starts, the LED lights up. When the battery is saturated, the LED indicator light goes out.
Ø It has operation status indicator.
ECG monitoring software parameters:
Ø ECG waveform display and data saving are performed simultaneously.
Ø You can query the monitoring results. ECG data is saved to the SD card of the mobile phone. The location of each QRS wave, whether the waveform is normal, and heart rate and other parameters are recorded. QRS detection accuracy can reach 99.81%.
Ø It can display QRS waveform at specified position and has positioning function.
Ø You can read the user manual online.
Ø The entire ECG waveform file can be viewed by sliding the button.
Ø It has the function of turning pages back and forth.
Ø It has the screenshot function, which is used to save the ECG waveform specified by the user.
Ø Real time display of heart rate changes.
Ø It has a time mark.
