Based on a current sensor module and based on the principle of the hall current which convert current into an analog voltage output; MCU (Arduino UNO R3) that includes AD converter can be read out and converted into measured current value; Suitable for SCM system powered by 5V power supply; Can measure AC and DC; Widely used in over-current detection current monitoring and other occasions.
An electronic brick is an electronic module which can be assembled like Lego bricks simply by plugging in and pulling out. Compared to traditional universal boards and circuit modules assembled with various electronic components electronic brick has standardized interfaces plug and play simplifying construction of prototype circuit on ones own. There are many types of electronic bricks and we provide more than twenty types with different functions including buttons sensors Bluetooth modules etc whose functions cover from sensor to motor drive from Ethernet to wireless communication via Bluetooth and so on. We will continue to add more types to meet the various needs of different projects. Electronic brick of current sensor is based on ACS712 sensor which can accurately detect AC or DC signals. The maximum AC or DC that can be detected can reach 5A and the present current signal can be read via analog I / O port. Features 1. Plug and play easy to use.
