Newsteo¿ï¥ÎNordicªºNrf9e5®a±Ú²£«~(­^¤å¤º®e)

Nordic Semiconductor ASA has announced that Newsteo has selected its nRF9E5 family of integrated 433/868/915-MHz ISM band transceivers for use in its latest wireless product solution. The system comprises three parts: RF Tokens (using an nRF9E5 transceiver), RF-to-PC USB key transceiver (again equipped with an nRF9E5), and RF Monitor software used to configure, control and collate data collected by the Tokens.



Nordic¡¦s nRF9E5 is a true system-on-chip (SoC) comprising a fully integrated RF transceiver, 8051-compatible microcontroller (MCU) and a 4-input, 10-bit 80-kS/s (kSample per second) analogue-to-digital converter (ADC). The nRF9E5 operates in the popular European 433- and 868-MHz ISM bands and the 915-MHz band in North America, Australia and Israel. The device is an ultra-low-power, low-cost transceiver with a data rate of up to 50 kbit/s.



Newsteo¡¦s 12 gram RF Tokens can run for up to 5 years from a single CR2450 3-V lithium coin cell and come pre-certified eliminating the need for lengthy certification approval. The Tokens are supplied in a 44 by 30 by 10 mm cuboid form factor for discrete mounting on target equipment, walls or pipes. Each transceiver responds to a ID code to avoid communication clashes, and incorporates on-board security to prevent unauthorized access. Each RF Token can simultaneously host several different types sensor (for example, temperature, pressure, force, constraint, acceleration, flow, current and light), while an on-board Flash memory stores from 2,000 to 2 million measurements.



Newsteo¡¦s RF systems allow customers to switch cost effectively from hard-wired to wireless sensoring. Applications include temperature and humidity sensoring in commercial greenhouses, cold chain logging and control and automation (for example of hotel room air conditioning systems), as well as intelligent sports applications (for example, logging runners in a marathon).
