I'd like use the TCA 355 for proximity switch product. Could you please provide manual regarding how to calculate inductive distance of components TCA355? and how to steady the inductive distance caused by ambient temperature variation? any compensation design proposal?

I just came into contact with Labview, designed a product counter, and asked how to wire the photoelectric sensor and the capture card. After I connected it, it was an NPN type, that is, it outputs a low level when an object is blocked, and the program I designed is a low power When the pin goes high, the count is +1, and now when I click to run the program, it will change the count from 0 to 1 without doing anything. Is there a PNP connection between the sensor and the acquisition card?

Hi there, is it possible to use INA3221 Current Sensor to measure only voltages at the three output channels without anything on the input bus? I am wondering if it is possible to use this module in a reverse direction, and have CH1, CH2 and CH3 voltage readings separately and maybe then allow CH1 to pass through the input bus using a switch transistor. Something like a voltage detect and then passthrough in the opposite direction from CH1 CH2 CH3 to input bus.

I used the accelerometer sensor of the PCB, and cooperated with the NI 4461 acquisition card to perform a vibration signal of an insect, and obtained such a signal. It stands to reason that the sensitivity of this sensor is very high. But even if I tap the tabletop that touches the sensor with my hand. The change in this waveform on the graph is also not obvious. Where is the problem? PS: Because my computer does not have a PCI slot, I bought a CPI-E to CPI interface, and then used an extension cable to connect the capture card to the computer. Does it matter?

The S8050, an NPN transistor, is suitable for audio amplification circuits, class B amplifiers. How can an S8050 transistor be used as a switch?
