Reusing Gyroscope - salvaged from old camera

Question

Hello, I am new in the community. Hope this is the right place for this question. I disassembled a camera and in one of the circuits there are two accelometers perpendicular to each other. I just want to learn how can I read and understand data from it. But I couldn't understand the circuitry. Could someone give me some pointers in that? I only have a multimeter as a testing device, by the way. Please find attached image.

Welcome to the E14 community. Your inquisitiveness will stand you in good here. It may also be a curse when the answers you seek are not forth coming. I would tend to agree with shabaz and see a more efficient road to the knowledge you seek by using a single board computer or microcontroller. You need to know what you don't know. Using a pre-existing configuration gives you that opportunity. You know it will work and you will know how it should behave. Now you just have to get it to do it. My first foray into this stuff was using some parrallax sensors. I got to explore the math involved using the components. I stopped short of taking a quadcopter installation and maintenance course. How those type of sensor are used to control a quadcopter is fascinating. Vacation with the family or a week in technical school? Yeah, I need to go on vacation with the family. Keep the camera components you can always go back and explore them later.

Hi Enes, With any part, you need to examine the datasheet, it will describe what you're requesting. You need to find the datasheet for the part (e.g. via google. Or if you somehow have the circuit diagram for your camera with the part labelled). Unless you find the datasheet, I don't think you can do much except probe it with the power applied to the camera and see what you see. That's 'reverse engineering. That would ideally require an oscilloscope, or a logic analyzer (logic analyzers are inexpensive but there is a learning curve), and not a multimeter. For a simpler way, Adafruit (and others) sell accelerometers on easy-to-use 'breakout' boards, for $5 USD. There are tutorials for them online (usually they require a microcontroller and some programming, for instance see 'Arduino') since they have a serial digital output stream. There are some accelerometers which have an output voltage and require no microcontroller or programming, but they are likely to be rare, and more expensive these days. Analog Devices is a manufacturer that had analog output versions.

They are Murata, I think. Based on the M in Circle logo ...
