System designers can speed time to market for wearable and healthcare products, says Maxim Integrated Products, with the MAX30102 pulse oximeter and heart rate integrated sensor module. The integrated pulse oximetry and heart rate monitor module integrates red and IR LEDs to modulate LED pulses for oxygen saturation (SpO2) and heart rate measurements.

Able to detect levels of the UVA and UVB light spectrum, the two-channel ZOPT2202 sensor from IDT, has sensitive photodiodes which, when coupled with the sensor’s patented infrared light suppression, deliver UV levels and also a contextual awareness in health and wellness applications in smartphones and wearable devices.

Designed to reduce the cost and complexity of wrist-based heart rate monitoring (HRM) applications, the Si1144 has a low-power optical sensor module, paired with an EFM32 Gecko microcontroller running the company’s HRM algorithm.

Suitable for power-sensitive applications, such as wearable devices, the u-blox 8 GPS/GLONASS receiver addresses power sensitive usage.
Compared with the earlier u-blox 7, it has increased tracking sensitivity, increased by 4dBm to -166 dBm. The enhanced odometer functionality, a new geofencing feature, and optimised pre-set power save modes can halve the power requirements for sport products, says the company.
AssistNow boosts GNSS acquisition performance, available online, offline or as an autonomous service. Positioning makes it suitable for all battery powered devices, especially wearables and sports tracking.
u blox 8 is pin-compatible with u blox 7. It will be available as a chip and as modules in several form factors. Customer samples will be available by Q2 2016.
