Ear Sensor (Shock & Temperature)

The customer in the Motosport racing industry had the desire to obtain quickly a tiny PCB mounted with sensors. The objective was to create an ear sensor.


  • Ear temperature measurement
  • High Impact shock detection
  • Tiny electronic parts
  • Tiny PCB
  • Embedded C Firmware development (ARM)

Kelsec successfully designed the PCB and the required firmware (in the central controller) for cyclic temperature measurement and shock detection.

  • Ear temperature monitoring using Melexis Mlx90615 device
  • High impact detection handled by STMicroelectronics H3LIS331DL High-g triaxial accelerometer
