Description
Product introduction
This module is mainly used to test people’s heart rate
This function can be realized by simply connecting a single-chip microcomputer and writing a corresponding program
We provide information on testing the heart rate of people using arduino microcontrollers
Features:
(1). With DC-DC isolated power supply, low voltage safety
(2). Test heart rate data is accurate. Working voltage: voltage 3.3—5V working current: 800uA operating temperature range: 0–60 degrees Celsius
