Title: Wearable Tracking Device for Miners
By: sunnyiut
Design Challenge: Safe and Sound Wearables
Blog number: 13
Intro:
This blog is about the Hardware design of the wearable device that will be mounted on the wrist of the Miners.
Objective:
The first part of my Project Proposal is to design a wearable device that contains the sensors for collecting the environmental information.
The Launchpad, sensor boosterpack and other necessary components in-together will be quite big and bulky to fit on the wrist. So, my objective is to design a customized board to make it wearable.
Components of the Wearable Device -
- MSP432P401r
- Sensors -
- OPT3001
- BME280
- TMP007
- TFT display
- Power supply
- Battery charger
- Selection buttons
Optional components [Not included in this project proposal] -
These components will be implemented in the Hardware but the Firmware integration is left for future work.
- MAX30100 sensor for Heart rate and SPO2
- WSP2110 sensor for air quality [spec. Benzene]
- BLE [RN4020] to send/receive beacons in between miners, in case of emergency
Board Design:
MSP432P401r [MCU and other supportive circuitry] - TFT display -
Sensors - Power supply -
Bluetooth Low Energy -
PCB:
3D Layout:
** that's basically the end of the designing the first part [wearable device] of my proposal. As the time is short, I'll try to develop the board later on, if I can manage some time.
Meanwhile,
I placed the order for PCB fab on 20th June.
Unfortunately, the delivery got stuck into EID vacation [it's a big one in my country
] and customs clearance
However, I have received it yesterday. I don't have much time left for the Project Submission.
So at first I'll post my blogs on the two other parts of my project proposal -
- Miners location detection based on RFID and
- Central monitor to display and log miners' location
My next blog post will be on Reading Miners' RFID tags to detect their location.
