A ceramic port is included in the design of the Bourns Model BPS140 pressure sensor to enhance its compatibility with certain harsh media, explains the company.
IoT
Precision positioning antenna has enhanced positioning
Antenna and RF antenna module manufacturer, Antenova, is now shipping its latest positioning antenna, Raptor. It is able to pinpoint a location to within centimetres, claims the company.
ST combines accelerometer and temperature sensor for tight spaces
A MEMS three-axis accelerometer and a temperature sensor are combined in the LIS2DTW12. Available from STMicroelectronics, the single die is designed for use in space-constrained and battery-sensitive detectors such as shipping trackers, wearables, and IoT endpoints. The sensing accuracy of 0.8 degrees C offers precision comparable with standalone standard temperature sensors, according to ST Microelectronics.
Low power Bluetooth microcontrollers support mesh networking
Two low power, dual-mode Bluetooth 5.0 and Bluetooth Low Energy (BLE) microcontrollers introduced by Cypress include support for Bluetooth mesh networking for the IoT. The CYW20819 and CYW20820 each provide simultaneous Bluetooth 5.0 audio and BLE connections, delivering low-power wireless management that enable music and voice commands for battery-powered fitness bands, health monitoring devices, and voice remotes. Designers can also use the microcontrollers to develop low-cost, low power Bluetooth mesh network devices that can communicate with each other and with smartphones, tablets and voice-controlled home assistants via simple, ubiquitous, and hub-free Bluetooth connectivity.
