## Description

desertcart.com: YHDC Split Core Hall Current Sensor HST21 300A/4V : Industrial & Scientific

Review: Excellent hall effect current sensor from Poland. - Works as advertised at an excellent price. Bought to monitor a inverter/charging system for an RV. I went with this hall effect sensor because I'm not a fan of big exposed shunts. I was planning to integrate it with an Arduino project. Seems reasonably accurate. It arrived in a timely manner. I was surprised it came from Poland. The manufacturer has a reasonable web site and they are OEM suppliers for industry heavy hitters like Siemens.
