sensors

So there are many electronic 'air' drumsticks in the market, such as Aeroband, Freedrum, Senstroke, Aerodrums, etc. I wanted to know what sensors do these use or might have used to do what they do. For example, the Aeroband Pocketdrum have a pair of drumsticks with sensors, and a pair of foot...

Hello everyone, I am currently working/struggling to get a thermal mass flow sensor (IST FS7) to behave like intended, regarding the response time. The sensors datasheet states that is has response time of t66% = 200 ms going from a low air velocity to a higher air velocity. I have build the...

Hello, Sorry 1) if this is wrong place 2) Dumb question. I am working on smart irrigation project, I have Arduino connected with 4 sensors and 1 actuator, Arduino collect data and send to ESP32 using Reyax RYLR896 Lora Module connected to it. I keep all PCBs in one waterproof box, but this...

I'm searching for any videos which explain and show me how to answer questions like this, as I am unable solve this question.

I am making a chess board with integrated AI for a year 12 school project and I am not sure what kind of components I will need to use to be able to sense what pieces are where at the start of each turn. I was thinking of using RFID but the range is too long I also thought about using smart card...

Good evening all, Background: I am final year Electrical & Electronic engineering student currently in the process of completing my undergraduate thesis. The thesis topic consists of making a low-cost, non-intrusive, battery powered electronic device that is small enough to fit in the punt (the...

Hi, I am currently trying to make an arduino based Power Meter. I will buy the SCT010T-D ct from YHDC. My question is the following. The ct says it has a DC 5v output at 5-10-20 etc Amps depending on the model. Does that mean the output is a sine wave with dc offset (which requires more...

Are there any motion sensors that can detect a person that is 80 feet away?

Hello, can you help me with this project? I want to design a circuit which counts up when the ENTRANCE SENSOR detects an object and counts down when the EXIT SENSOR detects an object. I created the circuit design attached below with the help of some tutorials on YouTube but I do not know what...

How are smart sensors different from normal sensors? What are the advancements in this field? How to design and implement a proximity sensor for industrial applications?

I need to develop solution for monitoring movement & rotation of components in 3D space (integrated logistical and production workspace). Components have a size of circa 0.5 x 0.25 x 0.25 meters. Both movement as well as rotation of components need to be measured. Workspace where components are...

Hi, I am trying to develop a Gas detector module to detect Methane (CH4) gas. I am using the 'ezPyro CH4 Gas sensor' (SMD). Now, the difficult part is resourcing the required Methane Gas. I believe I need small amount of Methane gas for lab testing. But I coudn't find any such supplier who...

Hi there, Recently, I have designed a new charge amplifier than can be used to implement a precision and low-cost interface for piezoelectric sensors. I have published an article about the novel proposed circuit in IEEE Sensors Journal. ( A brief information about the new proposed circuit has...

Hello AAC! Running into some issues with my current light switch design, and realizing that, if possible, I would like to change my setup to include some sort of sensor that can detect movement. Basically, my application for this bedroom light would be to have the light turn on and off based on...

Hello everyone, I'm trying to find out the model of the two chips on a temperature/humidity sensor. As you can see the surface of the chips have partially melted. I think I found the model of one of them (the long-one with 14 pin): ICM7556. I found this link to a datasheet But I can't find...
