By reading different values from the sensor, we can detect if is it light , dark or a value between them. Another element that we are going to use on this experiment is Piezo Buzzer.

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

As a biomedical equipment technician [Adam Outler] equipment needs to be in top working condition. The emergency room staff were complaining about erroneous noise on the electrocardiogram and it&#8… ...

In these short-term acceleration applications, a piezo-bender or piezo film sensor is the transducer of choice. A piezo transducer’s equivalent circuit is an ac voltage source in series with a ...

Because of the affordability and seeming ubiquity of the Arduino platform, they have been hard at work this last month trying to get their Geiger counter sensor board for an Arduino out the door.

HDK-America has released a small, piezo-resistive three-axis acceleration sensor, the HAAM-325B, measuring 3 mm x 3 mm x 1 mm. Just one-fifth the size of the previous generation product, it offers ...
