Smart Cities

IoT specialist, SensiEdge now offers the SensiSub system-on-module (SoM) starter kit, describing it as a board-level IoT sensor node. It joins the company’s Bluetooth-enabled SensiBLE IoT SoM, but delivers higher range and more reliable frequency bands to penetrate obstacles and reduce interference. The SoM is suitable for IoT applications in varied locations, including smart factory, smart home, smart grid and smart city deployments.

SensiSub is based on a low power Arm 32-bit Cortex-M4 CPU with FPU, and a range of serial interfaces (including SPI, I²C, UART, ADC, CAN, USB and GPIO). The SoM combines a Spirit1 low-power RF transceiver from ST Microelectronics, offering certified sub-1.0GHz connectivity (in three frequency versions: 433, 868 and 915MHz). A suite of customisable sensors includes a three-axis accelerometer, magnetometer and digital gyroscope, plus pressure, microphone, relative humidity, ambient light, temperature and UV sensors.

SensiSub’s hardware-ready configuration provides a complete, self-contained RF platform in a small form factor (20 x 30mm) that enables wireless connectivity without prior RF expertise. The SoM is therefore suitable for a range of applications that demand rich functionality, including smart metering, industrial lighting, and home and building automation, where it can capitalise on its long range, reduced interference and low power features of the sub-1.0GHz spectrum band.

The SensiSub IoT SoM is an industrial-grade customisable module for engineers looking to design IoT products without getting involved in either hardware development or production logistics. It allows developers to focus on their own applications, domain expertise and core competencies, rather than the underlying hardware platform or production logistics when creating products for the IoT.

SensiSub fits an array of coin battery-powered applications that require integration of multiple sensors with sub-1.0GHz connectivity, without compromising on cost and power consumption, says SensiEdge. It also shares the same small form factor as SensiBle, enabling customers to develop and build prototypes and proof-of-concepts using SensiBle, before transitioning to SensiSub for deployments requiring greater range.

Distributor Mouser Electronics now stocks the A71CH secure element from NXP Semiconductors. A ready-to-use security solution for next-generation Internet of Things (IoT) devices, the A71CH provides a root of trust at the IC level to deliver chip-to-cloud security out of the box. Designers can connect to IoT clouds and services without writing security code of exposing keys with the A71CH. Target applications include connected industrial devices, sensor networks, IP cameras, smart home devices, home gateways, and smart cities.

The NXP A71CH IC provides secure, zero-touch connectivity for IoT devices. This encrypted and authenticated interface-to-host processor can be securely provisioned with the required credentials for autonomous cloud on-boarding and peer-to-peer authentication. Featuring security functionalities such as encrypted key storage, ECC key generation and signature verification, and an encrypted vault for product master secrets, the chip is designed to help protect private information and credentials for mutual authentication.

The A71CH is designed for easy integration of security and cloud on-boarding through host libraries, example codes and various application notes, as well as the A71CH Arduino compatible development kit. The kit includes an A71CH Mini PCB board and Arduino-compatible interface board that seamlessly connects to many NXP LPC, Kinetis, and i.MX boards to support microcontroller and microprocessor development.

Mouser aims to empower innovation among design engineers and buyers by delivering advanced technologies. The distributor claims to stock the world’s widest selection of the latest semiconductors and electronic components for the newest design projects.
