As pointed out earlier, the sensor-head of the circuit is a 50 turns (25T top ... Let’s get on with testing the $5 Chinese metal detector module. Well, coming to the module’s key specifications, the ...

The project looks good with an LED module and a rotary encoder to set sensitivity. Pulse induction metal detectors use a single coil to send and receive short pulses. This differs from the more ...

high-accuracy module (11.8 × 8.6 × 2.5 mm) combining a three-axis accelerometer sensor (from ROHM’s Kionix Group) with proprietary earthquake-detection algorithms embedded alongside the sensor ...

“Rohm will continue to develop algorithms optimised for different vibration detection and expand its sensor module lineup. We will also leverage wireless technologies, such as Wi-SUN, that is ...
