ON Semiconductor has introduced RSL10 Multi-Sensor Platform powered solely with a solar cell. This complete solution supports the development of IoT sensors using continuous solar energy harvesting to gather and communicate data through Bluetooth Low Energy, without the need for batteries or other forms of non-renewable energy.
The latest introduction is an effort by the company to continue enabling battery-less and maintenance-free IoT with ultra-low-power wireless communications, small form-factor solar cell, and low duty cycle sensing applications makes it possible to develop and deploy totally maintenance-free IoT sensor nodes.
The RSL10 Solar Cell Multi-Sensor Platform is enabled by the RSL10 SIP, a complete System-in-Package (SiP) solution featuring the RSL10 radio, integrated antenna, and all passive components.
The platform combines the RSL10 SIP with a solar cell and a host of low power sensors from Bosch Sensortec, including the BME280 all-in-one environmental sensor (pressure, temperature, humidity) and the BMA400 ultra-low-power 3-axis accelerometer.
The combination will allow developers and manufacturers to create complete IoT nodes that are entirely powered through renewable energy or energy harvested from the sensor’s surroundings.
Commenting on the release of the RSL10 Solar Cell Multi-Sensor Platform, Wiren Perera, who heads IoT at ON Semiconductor, explained, “With this solution, established on the RSL10 Bluetooth Low Energy radio, we are proving that a battery-free and maintenance-free approach to smart sensor development is not only possible but can help manufacturers improve their designs.”
There are a growing number of IoT sensor applications where the duty cycle is low enough to support intermittent communications, allowing the energy needed to support operation to be harvested using renewable sources. The energy efficiency of the RSL10 is augmented by the highly efficient power management system and the ultra-low-power sensors implemented in the platform.
The Major Application of the RSL10 Solar Cell Multi-Sensor Platform include:
- Smart home and building automation – HVAC control, window/door sensors and air quality monitoring.
- Asset tracking – package open/close detection, shock monitoring,
- Temperature and humidity data logging
For easy development, the platform is supplied with all design files (Gerber, schematic and BoM) and customizable source code as part of a CMSIS software package.
The RSL10 Solar Cell Multi-Sensor Platform is available now from ON Semiconductor alongside a number of other energy-efficient rapid prototyping platforms for IoT.
