Sample Application

CSM37F70 is a module utilized in home-use professional body composition analyzers. It supports weight, body composition, and heart rate measurement through the built-in body bioimpedance measurement (BIM) circuit, weight measurement circuit, and algorithm microprocessor. The module supports weight measurement, with automatic wake up function of pressure scale; 8-electrode impedance measurement, built-in dual frequency excitation frequency of body composition algorithm, and supports body fat rate, muscle rate, water rate, basal metabolic rate, visceral fat grade, protein, bone salt amount, body age, body score, and many other parameters. It has a built-in heart rate algorithm that supports resting heart rate measurement.

(1) Supports 8-electrode impedance measurement, excitation frequency 25 kHz, 100 kHz

(2) Built-in body composition algorithm

(3) Supports resting heart rate measurement, built-in heart rate algorithm

(4) Supports weight measurement, with automatic wake-up function for pressure scale

(5) Supports UART communication, baud rate of 115,200 bps

(6) Supports OTA function, can upgrade the function and algorithm

(7) Wide input voltage range 3.6 V ~ 6.5 V

(8) Operating current 7.5 mA (typical), standby current 20 μA (typical, enables the automatic wake-up function of the pressure scale)
