What is an electronic brick? 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 electricity sensor is based on TA12-100 current transformer which can transform AC signals of large current into small amplitude signals. The maximum current 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. Compatible with the mainstream 2.54 interfaces and 4-Pin Grove interfaces in the market. 2. With use of M4 standard fixed holes compatible with M4-standard kits such as Lego and Makeblock. Specifications Compatible interfaces 2.54 3-pin interface and 4-pin Grove interface(1) Note 1: S for analog output port G for ground and N for not used pin. Electrical characteristics Parameter Min. Typical Max. Unit Transformation coefficient - 1000:1 - - Input current 0 - 5 A Output current 0 - 5 mA Sampling resistor - 200 - Ω Sampling voltage 0 - 1 V Working frequency 20 - 20000 Hz Working temperature -55 - 85 ℃ Dielectric strength - 6 - KAC/1min DEMO Connect S port of electronic brick of electricity sensor to A0 port of Arduino board and we will use the following program to read the analog value and the send it to computer for display via serial port.
