Working Principle of ACS712 Current Sensor with Arduino The ACS712 sensor operates on the Hall-effect principle. When current flows through the input terminals (IP+ and IP-), it generates a magnetic ...

Arduino can only measure voltage signals it can not "read" current signals. All I do is use a resistor. 0 to 20 mA through a 250 Ohm precision resistor gives me 0 to 5 volts. Your uc (Micro-controller ...

Current signals of 4-20 mA are commonly used in industrial applications to transmit process signals to controllers. Compared to analog voltage signals or digital communication, the current loop ...

Considering microfluidic technology, this work has been innovated to consist of monitoring, temperature control and cooling sections. The work consists of peltier a module attached to the heatsink and ...
