About this product
The WCS1800 is a Hall-effect current sensor module with two functions. It provides an analog output, conditioned by an operational amplifier and suitable for A/D conversion, and a digital switch output. The overcurrent threshold is preset by the user; when the measured current exceeds it, the switch output goes high and an LED indicator lights. Useful for current monitoring and overcurrent protection projects.

Frequently asked questions
How do I set the overcurrent limit?
The limit is set through the module's preset adjustment. The listing does not specify the adjustment method, so check the markings on the board or the module documentation before adjusting it.
Can the analog output be read by a microcontroller ADC?
Yes, the analog output is conditioned for A/D conversion. Confirm the module's supply voltage and output range against the ADC input range of your board before connecting.
