  • Good sensor

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:

    This module is really easy to use, it is well made and the board is tiny enough to use it in a lot of applications. Range voltage of 3 to 6v allows this module to be connected in a wide range of projects. It has an enable input that can be controlled by a uC in order to reduce power consumption when it is not being used. The led indicating a detection is really usefull when testing.

    Cons:

    The range is really poor, no more than 20 cm, even replacing the original adjusting potentiometers by others. The cost can be lower.

    OtherThoughts:

    If you not need more than 20cm detection range, this is a good sensor to have to play with it.

    Bottomline:

    If you have some electronic knowledge maybe you can built your own version with an increased detection range for less money. But if you don't need a higher detection distance and you just want something that works..this is a good choice
