ME216M: Design of Smart IoT Health Hub
March 2019 - June 2019, Stanford University
Part of ME216M: Introduction to Smart Product Design at Stanford University. This is a smart product design class which is at the cross roads of interaction design and mechatronics systems to create smart products in today’s consumer electronics world.
The problem prompt we were given was to develop a product that affected positive change to health and wellness of end users. As a team of 3 students at Stanford University, we came up with “Waking with Water”, a smart IoT health hub that aimed to initiate a healthy waking up routine for young professionals.
Design Process:
Our team aimed to create a health hub that serves as an alarm clock which also has calming LED lights that adjust color based on time of the day and intensity based on brightness levels. We decided to manufacture this hub by laser cutting some Maple wood and creating bends as seen in the pictures below. Several such laser cut pieces were assembled together and finally some wood stain was used to provide the walnut finish as seen in the thumbnail picture.
Electronics System:
In order to achieve the required functionality of the hub, our team used the ESP8266 microcontroller which has an inbuilt WiFi module. This was connected to a touch screen (to display time and to allow the user to tap to dismiss the alarm), an MP3 module and speaker (to play the alarm), a light sensor( to obtain the brightness level in the room) and LED lights (to display a color depending the time of day and the intensity based on brightness sensed). To determine the time of the day and hence color of light, the ESP8266 was made to read data from a Web API - darksky.net
Below is the schematic of the circuit that was used to obtain this functionality and the PCB layout which allowed us to fabricate a PCB for connecting the various components together.
