A prototype answers a question
Reliable readings? Enough radio range? An understandable interface? Each prototype must remove one specific uncertainty. ESP32-type boards combine Wi-Fi, Bluetooth and inputs/outputs: they speed up this phase without committing to manufacturing.
Test in the field, not on a desk
Humidity, distance and power supply change everything. We quickly install the prototype in its real environment and follow the readings from a small web console, as in our Sillage concept.
Prepare what comes next
A successful prototype is not a product. The next version deals with power consumption, security and updates. Our kick-off workshop helps decide what should go into production. See also: Bluetooth LE or Wi-Fi.
