PRODUCT SHOWCASE CPI waterproof switches Control Devices has added CPI waterproof switches to their product line. CPI switches are designed to cater to demanding Industrial and Defence applications, where efficiency and reliability of machine operation is essential under severe environmental conditions. Based on the users’ set parameters, the switches can qualify for an IP68 rating. They are protected with a thermoplastic or neoprene rubber cover, and are fully submersible – splashproof, waterproof and wash-down resistant. They perform under exposure to water, salt water, oil, sand, dirt, humidity, vibration, shock and temperature extremes. They also come in a selection of styles ranging from a pendant, rocker, plunger, limit and ball. Momentary and maintained functions are available. For installation, the switches can be mounted into a bracket to fit into confined spaces or a switch panel unit.

They feature the low-energy Bluetooth 5.2 specification, industry-leading security and a proven Zigbee stack. Based around an ARM Cortex-M4, the PIC32CX-BZ2 integrates a high-­performance 2.4GHz radio and supports a wide temperature range in a stand-alone package making it wellsuited for industrial applications such as industrial lighting and remote factory/building control. Home automation is at your fingertips with the PIC32CX-BZ2. It can be used to turn on living room lights, lock your front door and control your blinds remotely. You can even use Bluetooth to set up a Zigbee network and control it from your smartphone. The applications for this exciting new solution are endless. Be one of the first to get early access to Microchip’s development kit, user guides and example demos. The EA71C53A is an early access development kit for developers who want to explore and develop applications with Microchip’s upcoming Bluetooth 5.2 and Zigbee wireless solution. The kit is available now for US$88.

The BMP390 is an ultra-small, low-power and lownoise 24-bit barometric pressure sensor with vertical (z-axis) capabilities that enable accurate indoor localisation with smartphones in case of emergencies. The Bosch BMP390 barometric pressure sensor offers a pressure range of 300hPa to 1250hPa at 0°C to 65°C with typical relative accuracy of ±0.03hPa. The sensor features low 82 Silicon Chip power consumption of 3.2µA at 1Hz and a small 2 × 2 × 0.75mm form factor, making it ideal for a wide range of lowpower, altitude-tracking applications in smartphone and wearable devices. For development, Mouser also stocks the BMP390 Shuttle Board and the Application Board 3.0. Designed to be used together, the Application Board and Shuttle Board enable access to the BMP390 sensor’s pins to build prototypes. The minuscule, single-package BMP390 solution enhances design Australia's electronics magazine flexibility to allow easy integration, including Internet of Things (IoT) devices, smartphones, GPS modules, wearables, hearables and drones.
