The principal in building an infrared sensor is not rocket science, the critical factor is a high precision manufacturing process and calibration. And calibration again.
We have a lot of customers that take the Sensor Core and successfully install it to their own board. But when something goes wrong there are many factors to consider.
When you order a Sensor Onboard from us the warranties are extended and the risk on your behalf is diminished.
When we design and manufacture there is only one responsible ”head”, and most important, the calibration and the tests are performed after the board is manufactured (did we mention that before?).
