Dear Friends,
I would like to share my recent project "Renesas GR Lychee based smart home automation project" In this project I have used enOcean energy harvesting sensor modules which were received from element14 as sponsored as part of my Forget me not Design challenge Project, so I thought that this is good place to share the project and take valuable inputs from community members...
Here is final demo video of this project..
Abstract:
Our Goal is to design energy efficient IoT based home automation system for future smart home using GR Lychee. GR Lychee will be heart of the project, it is connected to internet via Wi-Fi connection using ESP32 onboard. Camera connected to GR Lychee detects any motion using motion detection algorithm running on GR Lychee and captures image when motion detected and send it to the android app running on user mobile via internet over Wi-Fi. Also user can capture and receive image of the home by Android App via internet.
Many Wireless sensors and actuators are communicating to GR Lychee using NRF24L01 Transceiver connected to GR Lychee using SPI protocol. The data of sensors are sent to Amazon AWS Server using WiFi by GR Lychee, where AI algorithm used to efficiently trigger Light/Fan/AC based on training data and reduce overall power consumption of the home. Further Android App can trigger the actuators manually too and all sensor data are displayed in mobile app in realtime. Each wireless sensor nodes are powered using normal room light/mechanical effort.
Sensors:
1. reed switch based magnetic door open/close sensor (STM 320 Solar Powered)
2. DHT 11 temperature and Soil Moisture sensor. (STM330 Solar Powered)
3. Rocker Switch (Mechanical Energy Harvesting)
Actuators:
1. RGB Mood Lighting Wireless Control module. (nRF24l01)
2. Relay module to turn on/off appliances. (nRF24l01)
GR Lychee Board : Its Heart of the project connected to nRF24l01 TXRX (2.4GHz ISM) using SPI Bus and EnOcean TCM210 RX (868MHz ISM) using UART Bus. Camera capture image on user demand as well as when motion detected. ESP32 provides Internet Access of GR Smarthome Hub via MQTT.
Android App is designed using Processing IDE and GR Lychee firmware designed using Gr-ide.
Android App provides real time access to camera and various sensor module data as well as user can control Relay switches and RGB LEDs. Captured images also stored on mobile phone storage with time stamp.
Here are few build pics...
I have attached source codes for readers reference...
Cheers,
Ravi
