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 ...

This post describes the preliminary results of a small Hall-Sensor module. This is widely known as KY-024 module. The KY-024 sensor module I got from an online retailer is inexpensive, and the ...

INA333_test.ino – This code reads the analog voltage from the VOUT pin of an INA333 (CJMCU-333) module using Arduino's analog input A0. The INA333 amplifies the small differential signal from a strain ...

Voltage sensors are structures within a protein that can sense the membrane potential. The movement of the sensing charges, combined with the configuration of the electric field, determines the extent ...
