PCB Mounted Strain Logger with Download Software

Project Description

We're looking to use a mounted PCB to log the strain seen by a larger mechanical part over an amount of time in a remote location.

• Form Factor

○ 15 mm Width x 50 mm Length

○ Single board

○ Mounting

§ Enough room on sides to slide into a channel

• Power Requirements

○ 1.2 Ahr-3.3V Battery must last 6 months on standby, and 300 hours of high frequency logging measurements

• Measurements

○ Logging Frequency

§ Times that are "In Use" - 1 sec

§ Standby - 10 minutes

○ Hours of use

§ "In Use" is defined as any of the strain measurements above their configurable threshold

○ Temperature

○ Strain on PCB

§ Torsion

§ Bending

§ Axial compression/expansion

• Hardware Requirements

○ Utilize dsPIC microcontroller

○ Minimal components

○ TTL UART communication

• Software Requirements

○ Configure settings/thresholds

○ Download from logger

○ Export measurements to CSV in fact table format

§ Date time, measurement name, measurement value

Skills: Circuit Design, Electrical Engineering, Electronics, Microcontroller, PCB Layout
