Health care IoT using Renesas Synergy
With IoT becoming the buzzword and rather a new reality in the embedded systems industry, and with the emergence of new technology trends and rising customer expectations, there is a need of reducing the product development cycles and providing cost optimized quality IoT solutions. The many uses of Internet of Things (IoT) in healthcare are changing business in medical industry. Mobile medical applications, wearable devices, telehealth systems being some of internet of things applications in healthcare. Internet of Things healthcare devices allow patients to capture their health data and hospitals to use IoT to keep track of the location of medical devices, personnel, patients etc.
HealthCare IOT on Renesas Synergy platform allows the monitoring of sensor data remotely using Wi-Fi / Ethernet network. The Renesas Synergy Platform used in the HealthCare IOT is the SK-S7G2 Starter kit with the Renesas Synergy S7G2 240-MHz ARM® Cortex®-M4 Micro-controller. iWave Systems developed both Hardware and Software for this Medical Healthcare IoT device to cater to the growing Healthcare market. The sensor adaptor board is compact in design with sensors like Body temperature, Ambient temperature, Air pressure ( and optional sensor like Heart rate+ SPO2, Accelerometer and Gyroscope). The Adaptor board can be easily mounted over the Renesas Synergy Kit.
iWave has developed MQTT IoT protocol library with publisher and subscriber support on Synergy platform for communication with Cloud Server.
Developed the MQTT Publisher application (using MQTT library) for sending the sensor data to MQTT cloud server using MQTT Protocol via Wi-Fi /Ethernet. The Publisher Application sends the sensor data along with a specific topic to the MQTT cloud server. Based on this topic the server decides which MQTT client has to receive the particular message. Any MQTT Subscriber Application which runs on Android Mobile/ Tablet can connect with the MQTT cloud server with the registered topic and receive the live updated sensor data.
We can re-use the existing design such as MQTT Cloud communications APIs, Sensor reading application, etc for other product verticals like industrial, Automotive etc.
- IoT application will launch automatically, which will capture the sensor data and send it to the cloud using MQTT IoT protocol. The communication medium is either Wi-Fi or Ethernet.
Using open source MQTT IoT application(MQTT Dashboard) on any mobile or Tablet, We can connect to the cloud and download the sensor data that was captured on synergy platform.
The Renesas Synergy SK-S7G2 evaluation kit uses the Renesas Synergy S7G2 240-MHz ARM® Cortex®-M4 microcontroller (R7FS7G27H3A01CFC) with 4 MB of flash, 640 KB of SRAM, and IEEE 754 single precision Floating Point Unit (FPU). It supports interfaces like USB Host/Device, Ethernet, SPI, I2C, UART, TFT LCD, QSPI Flash etc.
