Can anybody guess or does anyone know what lifespan can be expected of this piezoelectric sensor - https://www.sparkfun.com/products/10293 - with a weight glued to it and used inside a passenger vehicle ?

  • \$\begingroup\$ What does the datasheet say? \$\endgroup\$ – Leon Heller Jun 27 '17 at 11:34

    \$\begingroup\$ That'll be hard to guess. I guess mechanical reliability will depend very much on the weight and the mounting, as well as how well you're able to protect the cables and solder joints. If you need the reliability, dedicated, enclosed vibration sensors are probably a better choice. \$\endgroup\$ – Marcus Müller Jun 27 '17 at 11:36
  • \$\begingroup\$ That page also has this on it. Why wouldn't you use it? \$\endgroup\$ – Dave Tweed Jun 27 '17 at 14:33
  • \$\begingroup\$ @DaveTweed tried it. It is much too insensitive for my purposes. \$\endgroup\$ – kellogs Jun 28 '17 at 8:50
