Mini-ECGIt is a high performance, low power single lead ECG monitor module with Bluetooth interface and TF card interface. The ECG data can be transmitted to the ECG data processing software of the mobile phone through Bluetooth, and can also be saved to the local TF card. It can be used directly for ECG monitoring or two development.
Circuit board technical index:
O The common mode rejection ratio of the signal input terminal: 80 dB (DC to 60 Hz)
O The fast recovery function reduces the setup time of the filter.
O Automatic detection of lead shedding
O HBM ESD(anti human electrostatic discharge) rating: 8kV
O Input impedance10||7.5 GOmega||pF
O Input voltage noise (RTI) peak to peak voltage noise (F = 0.5 Hz to 40 Hz) 14 P-P V P-P
O Filter design: a dual pole high pass filter with a cut-off frequency of 0.3 Hz and a double pole low-pass filter with a cut-off frequency of 37 Hz.
O 24High precision sigma delta ADC
O Low power Bluetooth chip BLE, receiver sensitivity: -93 dBm
O Mobile phones can monitor and process ECG signals through Bluetooth.
O Rechargeable battery powered (3.7V, 400mAh) can be continuously monitored for 24 hours by continuous ECG.
O The charging voltage is 4.35V~ 6 V, charging through the MiniUSB interface
O With charging indicator, the LED lights up when charging starts. When the battery is saturated, the LED indicator lights go out.
O A light with a running state.
O With TF card socket, ECG data can be saved to local TF card.
ECGMonitoring software parameters:
O ECGWaveform display and data preservation are carried out at the same time.
O The monitoring results can be queried. ECG data is saved to the phone’s SD card, eachThe position of the QRS wave, the waveform is normal, the heart rateAll the parameters are recorded. The detection precision of QRS can reach 99.81%
O You can display the specified position of the QRS waveform, with positioning function.
O You can read the instructions online.
O Through the sliding button, you can browse the entire ECG waveform file.
O It has the function of front and back pages.
O It has the function of screenshot, which is used to save the user specified ECG waveform.
O The change of heart rate was displayed in real time.
O It has time mark.
