This post is in response to a reader who asked about detecting mains electricity using a microcontroller. The easiest and safest way to detect mains electricity using a microcontroller is with an ...

When taking measurements from analog sensors located at long distances, voltage drops and noise can affect precision of the readings. Therefore, a voltage-to-current (V/I) module is needed to transmit ...

Out of curiosity, I bought a strain gauge sensor module after it appeared on sale. This write-up is fuzzy, since I decided to write based on a quick inspection of it. Have fun reading my little post ...
