Overview
BMH03201 is a digital blood pressure module pairing a high-performance analog front end with a 24-bit ADC to output blood pressure and heart rate. Factory-calibrated (the sensor can be used or replaced without software re-calibration), it lets the host read results over UART, suiting blood pressure monitors, blood-pressure/glucose combo devices and health wearables.
Features
- Pressure range 0–300mmHg, pressure accuracy ±3mmHg
- Heart rate range 40–200BPM, heart rate accuracy ±5%
- 2.7–5.5V wide supply, low-power standby
- Built-in 24-bit ADC, factory-calibrated, lowering whole-unit calibration cost
