HRM-COMB1 is a fully integrated biosensor module developed by WestMicro, a Canadian technology company. This all-in-one solution combines heart rate monitoring, motion detection, and sleep tracking into a single compact unit. It is designed for use in mobile medical devices, wearables, smart headphones, and safety helmets. The module includes all necessary hardware, software, and algorithms, allowing it to operate independently without the need for external components.
The HRM-COMB1 features a waterproof stainless steel housing, an LED light source, a high-precision ADC, signal conditioning circuitry, an MCU, and advanced algorithms for heart rate and step counting. Users only need to connect a lithium battery, and the module can immediately output accurate biometric data. By handling all aspects of biosensor design, HRM-COMB1 significantly accelerates the development of wearable and medical devices, reducing time-to-market.
Operating on a voltage range of 3.6–4.5V, the module can be directly powered by a lithium battery. It includes a built-in 200mA LED driver, making it suitable for detecting heart rate even in dark skin tones. Communication is supported via I²C or UART interfaces, and the module can be turned off via software, with a standby current of less than 1µA. The hardware also supports oximetry and can be updated remotely through firmware upgrades.
