EM7028 series is a low-power I2C interface module includes Heart Rate Sensor(HRS) and internal LED Current Drivers with 2 Green LED. It can work in both continuous mode and pulse mode. It is designed for applications of Heart Beat Rate detection esp. such as smart watch etc. Heart Rate Sensor in continuous mode is designed to monitor heart rate by optical detection. A 16-bit ADC detects the result constantly with adjustable gain and resolution. Heart Rate Sensor in pulse mode is designed to monitor heart rate by optical detection in low-power. It also acts as a proximity sensor with rejection of ambient light noise. In order to removing component variations and eliminate offset caused by IR reflection, 2 registers were specially defined for compensation and high dynamic range of detection. HRS in continuous mode stores ADC output result into HRS1 registers, while HRS in pulse mode stores ADC output result into HRS2 registers. All pixels are controlled by analog-MUX in different modes. 艾普柯微: 心率传感器:EM7028 EM7029 长距离传感器:EM30918 EM30916 EM30917 三合一光感:EM30718 EM30719 更多详情欢迎来电咨询
