Nordic Semiconductor has announced that ConnectedYard has selected Nordic’s nRF51822 Bluetooth Low Energy (BLE) SoC to provide the wireless connectivity for pHin, a smart water care solution designed to simplify the care and maintenance of backyard swimming pools and hot tubs. pHin combines an nRF51822 SoC- and Wi-Fi-enabled smart monitor and smartphone app that monitors water chemistry and temperature around the clock and notifies customers when they need to take action.
The pHin Smart Monitor floats in the pool or hot tub and continuously monitors water temperature and water chemistry—including pH and oxidation reduction potential (ORP)—and then wirelessly sends the water chemistry data over the Nordic SoC-enabled Bluetooth LE connection to the pool owner’s Bluetooth 4.0 (or later) smartphone and the ‘pHin WiFi bridge’. The data is also available via the pHin Partner Portal, which allows retailers, service technicians, and pool builders to remotely monitor water conditions and provides features that help drive consumers back to their local retailer for chemicals and other products. pHin uses a coin cell battery to achieve over two years of battery life between replacement, thanks in part to the ultra low power consumption of the nRF51822 SoC.
Nordic’s nRF51822 is ideally suited for Bluetooth LE and 2.4GHz ultra low power wireless applications. The nRF51822 is built around a 32-bit Arm® Cortex M0 CPU, 2.4GHz multiprotocol radio, and 256kB/128kB Flash and 32kB/16kB RAM. The SoC is supplied with Nordic’s S130 SoftDevice, a Bluetooth 4.2 qualified concurrent multi-link protocol stack. Nordic’s software architecture includes a clear separation between the RF protocol software and the application code, simplifying development for ConnectedYard’s engineers and ensuring the SoftDevice doesn’t become corrupted when developing, compiling, testing and verifying application code.
