sensor unit
The Time-of-Flight sensor module with the tiny dimensions of LxW=10x17mm measures distances to a target up to 2m. The board has to be configurated with an additional controller unit in order to transfer proximity data. Both PCBs are linked either with up to 50cm flat-ribbon-cable or can work as 1 unit with dimensions of LxW=35x17mm. Then the controller unit transmitts distance values via serial interface to a master periphery. In autonomous mode the unit sets an output, if the objects' distance reaches a limit.
With the initial configuration the distance ranges for minimum and maximum threshold are adjusted, the data format is set and the behaviour of the output pin (impuls or continuous) is chosen. The hardware is ready to connect a 3V-DC motor or a bistable relay.
As an application the unit could be used for counting or recognition of objects within a defined range as well as a level meter.
