    Question about SCT's

    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...

    Up/Down Counter with 2 input sensors to trigger clock

    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...

    Object movement & rotation detection in electromagnetic field

    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...

    Gravity Sensor for Light Switch

    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...

    Microchips package surface partially melted. Do you recognize the model? It is a temperature/humidity sensor.

    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...
