<p>This module has two main functions. The first function is the analog signal followed by the op amp, which is suitable for A\/D conversion.</p> <p>The second function is the switch signal, which can pre-set the current limit value. When the actual current value is the pre-set current value, the switch signal change from low level to high level, and there be an LED indicator to indicate. Simple and easy to use.</p> <p>Application areas: AC and DC current detection; motor stall detection; leakage detection; multi-channel current detection.</p> <p>Application: Intelligent car motor overcurrent detection, stall protection current detection, short circuit protection testing, demonstration teaching experiments and other occasions to facilitate the secondary development.</p> <p>Main chip:LM393 op amp, WCS2702</p> <p>Working voltage:DC DC5V</p> <p>With signal output indication</p> <p>Current detection range is wide DC\u00B12A AC:1.4A</p> <p>Current detection resolution is 1V\/A</p> <p>Output overcurrent signal indication</p> <p>Overcurrent signal setting critical point is adjustable, and the setting resolution is 0.1A</p> <p>With mounting holes, it is convenient for firmware installation</p> <p>Sampling current conversion analog signal output, which can be connected to ADC, TTL level signal output, and can be connected to 10-port control of single-chip microcomputer.</p> <p>The output signal is: analog signal and switch signal</p> <p>Colour:Black</p> <p>Material:PCB+electronic components</p> <p>Package Contents:</p> <p>1 * Current Sense Sensor</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +\/- 1-3cm.</p>
