SensiEdge portable BLE module accelerates IoT applications

A portable IoT module from SensiEdge comes in a 17 by 40mm form factor and is powered by a rechargeable Li-ion battery.
 
The Sensible 2.0 is packed with a variety of sensors such as ambient light sensor, UV sensor, pressure sensor and relative humidity sensor, as well as a microphone. It is for use as an IoT application accelerator and features an accelerometer and magnetometer so the device can be used as a digital compass, pedometer or to measure vibration levels.
 
The Israeli company’s module runs on the all-in-one Bluetooth 4.2 module SPBTLE-1S from ST Microelectronics. This is a certified module that includes the BLE v4.2 stack and the low-power Arm Cortex-M0 32bit core. It has been designed to leverage the BlueNRG-1 integrated DC-DC step-down converter to achieve low power consumption in active mode.
 
The module runs at 32MHz, which is more than enough for most applications. In addition, the module has 160kbyte of flash and 24kbyte of embedded RAM with data retention.
 
The module is compatible with the STBLE Sensor application available for Android and iOS. This programme makes it easier to read values and send them to the cloud. Also available to designers is Sensible Windows, a SensiEdge application for Windows. The source codes of both programmes can be found on the GitHub, and its licence allows designers to edit their source codes based on their requirements.
 
Sensible 2.0 is an industrial-grade customisable device for design engineers looking to design IoT products without getting involved in either hardware development or production logistics. A key benefit is it allows developers to focus on their applications, domain expertise and core competencies, rather than the underlying hardware platform or production logistics when creating products for the IoT.
 
The software code is available online and it can be customised. For example, it is possible to configure an external flash memory on the board to store sensor measures if a Bluetooth LE connection is lost; when the connection is restored, all data received during this downtime can be transferred.
 
Sensible 2.0 is available from Arrow Electronics and Mouser.
 
Founded in 2015, SensiEdge is led by Milan Yudkovich, a hardware expert with practical engineering experience solving technical problems for the entire design cycle. Sensible, the company’s first module, is a hardware-ready platform for developers and entrepreneurs. The current product roadmap includes a Sensisub module, as well as SensiLoRa, a LoRa-enabled IoT module.
