Low-cost sensor node SoM lowers barriers for IoT development

IoT expert SensiEDGE have announced a new SensiSUB system-on-module (SoM) starter kit, a board-level IoT sensor node. Building on the success of the company’s Bluetooth-enabled SensiBLE IoT SoM, SensiSUB delivers higher range and more reliable frequency bands to penetrate obstacles and reduce interference.

The new device is ideal for advanced Internet of Things (IoT) applications, including smart factory, smart home, smart grid and smart city deployments. Featuring 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), SensiSUB combines a SPIRIT1 low-power RF transceiver from ST, offering certified sub-1GHz connectivity (in three frequency versions: 433 MHz, 868 MHz and 915 MHz), with a suite of fully customisable sensors (including 3-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 (20x30mm) that enables wireless connectivity without prior RF expertise. As such, it is suitable for a wide range of target markets and applications that demand rich functionality, including smart metering, industrial lighting, and home and building automation. The long range, reduced interference and low power features of the sub-1GHz spectrum band make it an ideal fit for these IoT applications.

“Our new SensiSUB is a certified solution that helps developers with limited or no RF expertise accelerate the design phase of projects and reduce the time-to-market for IoT applications,” explained Milan Yudkovich, founder and CEO of SensiEDGE. “As seamless connectivity becomes a standard requirement, this IoT module helps product and system designers integrate complex RF functionality into their prototype embedded designs, enabling a new generation of makers to more easily realise their concepts.”

The SensiSUB IoT SoM is an industrial-grade customisable solution 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 a vast array of coin battery-powered applications that require integration of multiple sensors with sub-1GHz connectivity – without compromising on cost and power consumption. 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.

Tick-Tock: What Your Engineers Could be Spending Time Doing if They Weren’t Stuck Designing a Display?
As soon as any design project is embarked upon, the clock starts ticking. The length of time needed to develop a system can impinge heavily on its commercial success. Windows of opportunity could be missed if it takes too long to complete, with products from rival companies gaining greater market share.
