[Muris] is pumping out the home lighting hacks. He developed this motion sensing module as an add-on to the IR switch we saw last week. There’s some kind of fuse box above his entry door and its white ...

Automated test stations don’t always need proprietary test tools. Using a microcontroller, a PC, and free software tools, we developed an automated test station to test and align motion sensors. Test ...

The LSM320HAY30 integrates a three-axis digital accelerometer with a two-axis analog gyroscope in a single module, a feat that allegedly improves performance, boosts reliability, reduces size, and ...

The LSM320DL multi-sensor module provides what the company says is five degrees of freedom. In essence, the integration of a three-axis digital accelerometer with a two-axis digital gyroscope in a ...
