This sensor from the Troyka module series will determine the current in DC or AC circuits up to 5 A.
The sensor is suitable for monitoring current draw, updating information on load changes, or even raising an alarm when your system is de-energized.
The current sensor is based on the ACS712 microcircuit.
The resultant output of the sensor is an analog signal. In the absence of a current, the sensor outputs half the supply voltage. When a current appears, the signal voltage either goes towards zero or the supply voltage and is proportional to the strength of the measured current (+/-).
Connect the sensor via 3-pin jumper cable to receive a signal from the scanner. The 3-pin jumper cable needed for the connection is included in the kit.
There are several different ways to wire this module:
Troyka Shield. The most straightforward method. Connect the module to a pin group on Troyka Shield with the 3-pin jumper cable and you’re ready to interface with it from your Arduino.
Troyka Slot Shield. The best choice for quick prototyping. Using slots on the shield, you can get rid of cables. The module will be held securely in place using both pin headers.
Breadboard. For advanced use. Troyka pin headers have 0.1” spacing which is compatible with any breadboard. Simply wire the module like you would do with any IC.
