The Module is made from a dedicated benchmark IC and high-precision current sensing resistor, proving a more stable constant current, (when 20°C to 100°C constant current 1A, temperature drift less than 1%); and therefore it is particularly most suitable for LED driver applications. The output current of the module can be raised up to 10A(for continuous use it is recommended up to 8A with additional cooling fan). To enhance the stabilization in output voltage has four high-frequency capacitance which gives the lower output ripple. Double heat sink design provides easy and fast heat dissipation. MOS Schottky diode independent heat sink, which heat dissipation is good, and won’t affect each other. Also using large size Sendust Core and double pure copper wiring, improve working efficiency, reduce fever.

This WiFi relay module carries an ESP8266 WiFi module and microcontroller. It will send the serial port instructions to the cell phone APP and Implementation within the local area network (LAN) for wireless control relay. This module is ideally suited to controlling larger voltages in your project through WIFI. This is a 2 channel relay module that can be used to activate up to 250V AC and 30V DC. This allows you to build in device control, operating remote lights, or triggering systems when the module is supplied with a signal from an ESP8266 module. The module has an LED that lights relative to the state of the module. A red power activation LED that lights when a signal is received on the IN pin. When a signal is received an audible click can be heard as the relay triggers, connecting the output pins. The relay is controlled via the included ESP8266. This will require configuration via UART prior to full operation. Once it is programmed and powered it will look after itself, making it ideal for use in internet of things IOT based projects.

The WCS1700 current sensor provides economical and precise solutions for both DC and AC current sensing in industrial, commercial, and communications systems. The unique package provides easy implementation without breaking the original system and makes current sensing possible. Typical applications include motor control, load detection and management, over-current fault detection, and any intelligent power management system, etc. The WCS1700 consists of a precise, low-temperature drift linear hall sensor IC with temperature compensation circuit and diameter 9.0mm through-hole. Users can use the system’s own electric wire bypass it through this hole to measure passing current. This design allows system designers to monitor any current path without breaking or changing the original system layout at all. Any current flowing through this hole will generate a magnetic field that is sensed by the integrated Hall IC and converted into a proportional voltage.
