IR Sensor Specialist for Outdoor Motion Detection
Budget: $50 – $0 USD
Infrared (IR) Sensor Engineer – Outdoor Motion Detection & Prototype Design (ESP32 / Arduino)
Job Description
We’re looking for an experienced Infrared (IR) and optical sensor specialist to help design and validate a motion-detection system that can operate reliably outdoors and in full sunlight.
The ideal candidate will assess the feasibility of using IR-based detection (reflective or break-beam) in bright environments, recommend suitable sensor modules and configurations, and design a proof-of-concept circuit or PCB that can integrate with an ESP32 or Arduino microcontroller.
You’ll be advising on both hardware design and signal reliability, ensuring stable detection without false positives from ambient light or environmental noise.
Responsibilities
Evaluate IR/optical sensing options for outdoor motion detection
Recommend emitter/receiver models with daylight interference mitigation
Design or simulate a small prototype circuit (ESP32 or Arduino compatible)
Optimize optical geometry, shielding, and filtering for reliable triggering
Optional: provide sample code or logic for trigger validation
Requirements
Proven experience designing IR or optical sensing systems
Strong understanding of photodiodes, break-beam, and reflective IR setups
Experience mitigating ambient light interference and noise
Proficiency with ESP32, Arduino, or similar MCUs
Familiarity with signal conditioning, analog/digital filtering, and low-power design
Deliverables
Feasibility assessment (short written report)
Recommended sensors and schematic
Optional: breadboard or PCB layout for prototype testing
Optional: example test code
Project Details
Type: One-time consulting + prototype design
Timeline: Deliverables within 7–10 days
Budget: Open — please include your proposal or hourly rate
Preferred Qualifications
Electrical Engineer or Applied Physics background
Experience with outdoor sensing devices or robotics
Familiarity with Altium, KiCad, or other PCB tools
To Apply
Please include:
A brief description of your experience with IR or optical sensor systems
An example of a previous project involving daylight IR detection or motion sensing
