GENERAL DESCRIPTION
The HL8018 Heart Pulse Detector is a single chip AC Type Photo-sensing heart pulse detection system. With built-in power regulator, the HL8018 has higher immunity from power noise, which is induced by buzzer or other devices.
FEATURES
- Wide operating voltage range (2.4V to 5V)
- AC type photo-sensing detection
- Built-in power regulator
- Wide operating range in different light environment
