Sensor Design & Integration
Breathing perception into products through precise sensor selection and integration. We work with a vast array of sensors to capture environmental, motion, and biometric data.
We specialise in sensor fusion, low-noise analogue signal conditioning, and high-frequency data sampling. Whether it is IMUs for motion tracking or specialised chemical sensors, we ensure accurate data capture and processing.
What this includes
- Sensor selection on accuracy, power, cost and supply risk
- Thermal isolation design for temperature, humidity and gas sensors
- Low-noise analogue front ends and ADC selection
- IMU calibration and sensor fusion firmware
- Environmental, motion, pressure and biometric sensing
Temperature, humidity and gas sensors that read true
Environmental sensors such as the SHT4x, SGP4x, BME68x and CO2 sensors measure the air around them, and on a small board that air is warmed by the processor, the radio and the regulators. A sensor a few millimetres from a hot component can read several degrees high and report humidity that is wrong as a result. We model heat flow through the PCB from every heat source to each sensor, then design milled isolation slots, copper keep-outs and placement that cut the coupling, and check the result against real routing before the board is built.
Analogue front ends and signal conditioning
Many sensors output small signals that are easy to bury in noise. We design low-noise amplification, filtering and reference circuits, choose ADCs on resolution, sample rate and power, and lay out the analogue section away from switching supplies and digital edges so the data you collect reflects the physical world rather than the board.
Motion, position and sensor fusion
IMUs, magnetometers and pressure sensors are cheap, but raw readings drift and disagree. We write the calibration and fusion firmware that turns them into stable orientation, motion and activity data, and test it on the real product in the way it will actually be used.
Common questions
Why does my humidity or temperature sensor read high?
Usually because the board is heating it. Processors, radios and regulators warm the copper around them, and a sensor nearby measures that heat as well as the air. The fix is a mix of placement, copper keep-outs and milled slots that isolate the sensor, plus firmware compensation where some offset remains. We can analyse an existing board and tell you how much of the error is self-heating before you change anything.
