The platform combines Dialog’s DA14580 Bluetooth SoC with three low power sensors from Bosch Sensortec: the BMM150 for thre axis geomagnetic field measurement; the BME280 pressure, humidity and temperature sensor; and the six axis BMI160, which combines a three axis accelerometer and three axis gyroscope in one chip.
The resulting unit, built on a 14 x 14mm PCB, consumes less than 500µA from a 3V coin cell when updating and transferring all data wirelessly to a smartphone.
Udo-Martin Gomez, pictured, Bosch Sensortec’s CTO, said: “The result of this close cooperation is the world’s lowest power Bluetooth Smart connected sensors platform. Higher functional integration and lower power consumption are key design goals for devices at the heart of mobile consumer electronic products. From our companies’ joint experience, we see many opportunities to deliver competitive advantages for our customers by creating smaller, highly integrated and more energy efficient smart connected solutions.”
Mark Tyndall, senior vp of corporate development and strategy with Dialog, added: “Our work with Bosch Sensortec is bringing together best-in-class Bluetooth, power management and sensor technologies that enable our customers to develop high performance, innovative products with exceptionally long battery life. Combining the complementary talents of our respective design teams enables us to keep customers at the forefront of technology as the IoT market continues to evolve.”
