Industrial grade low power wireless connectivity for building automation and sensor networks
Nordic Semiconductor today announces that Shenzhen Minew Technologies, a Shenzen, China-based manufacturer of Bluetooth® Low Energy beacon technology, has selected Nordic’s nRF52832 Bluetooth® LE System-on-Chip (SoC) for its ‘S1 Sensor Beacon’, designed to collect and report real-time temperature and humidity data in industrial, agricultural, and home applications.
The S1 Sensor Beacon has a compact 50 by 50 by 15mm form factor, weighs 26g, and comes in an IP66 rated dust- and waterproof-case with an operating temperature range of -40 to +70⁰ C, making it suitable for use in harsh industrial environments. Temperature readings are accurate to ±0.5⁰ C, while humidity readings are within 2.5 percent relative humidity.
The sampling rate for temperature and humidity readings is 1 Hz, with the collected data transmitted via Bluetooth LE connectivity provided by Nordic’s nRF52832 SoC to iOS or Android Bluetooth 4.0 (and later) smartphones and tablets running BeaconSET application software. From the BeaconSET app, users can check real-time temperature and humidity data, as well as view historical temperature and humidity changes represented on a curve graph. The data can also be transmitted to a network gateway and stored in the Cloud, allowing for online PC-based data analysis.
In the absence of a receiver or network connection, the nRF52832 SoC’s 512kB of Flash memory allows the S1 Sensor Beacon to store collected data which can then be downloaded from the device at the next opportunity
