Electronic – Are pins supposed to have the same thickness by some standard

jumperpinsstandard

I bought a DHT-22 temperature sensor, some other sensors, and some jumper cables. The cable and the pins on other sensors and a Raspberry Pi fitted well, but the pins on DHT-22 seem thinner. The jumper cables cannot stick to the pins, though they still work. I wonder if this is normal or the DHT-22 is a defective one.

That is, are the pin thicknesses supposed to be the same by some kind of standard?

There are many standards.

Wires, jumpers, sockets, and other parts made for use with solderless breadboards are made to fit together. I don't know if there's an official standard for them, but the companies who make them make things that work together.

The DHT-22 is not made to whatever standard that breadboard parts are made to. The DHT-22 is made to be soldered to a PCB. Its pins don't need to follow the standards that solderless breadboards follow.

There's nothing wrong with your jumper wires and there's nothing wrong with the DHT-22. They are just made to different standards and don't play well together.
