Will also equip the PCB with an acceleration and gyroscope sensor to estimate forces and change of position. The plan is to base the BLE on the BLE mesh topology/protocol. The solution can also be used for tire temp measurements.
The layout and routing of the prototype PCB is finalized, but not set into production.
IR sensors, factory calibrated to measure up till 1100 degree C, are tested on a Bluetooth Eval kit. Tricky unit to work with. Took some effort to make it work, but what a nice feeling when it worked :-)
