Wearable Prototype for Behavioral Monitoring
Budget: $10 – $1,000 USD
I'm looking to hire an experienced hardware engineer who can design and deliver a real, working prototype — not just schematics or theory.
This is for a wearable device that collects behavioral data and uses Bluetooth passthrough to sync with a mobile/web app. All data must route through a secure channel to private cloud servers (not stored locally).
What I Need:
Design of hardware + firmware using ESP32 or similar
Integration of the following components:
VL7700 or similar light sensor
TMP36 temperature sensor
OV2640 camera module (or compact equivalent)
ATGM 336H GPS module
Contact sensors
ADS1115 I2C expander
Deep sleep logic (ULP) for power saving
Compact, wearable-ready PCB
Working prototype (can be video demo or mailed)
Full BOM and testable schematic
What I Expect From You:
Proof of past work with actual hardware (not just designs)
Demo video or clear photos of a working prototype you’ve built
Willingness to sign NDA and IP assignment
Clear communication and ability to stick to deadlines
