This feature is used in automatic water equipment,allowing the water level is maintained at a low level and high level between. When the function switch when pressed, when the high-water relay (external solenoid valve) begins to drain, the water level drops below the low water relay off (solenoid valves stop working) until the water level rises again to the high-water relay pull again, the above process cycle. This feature is used in automatic drainage device, allowing the water level is maintained between low water and high water level.

ACS714 5A 5V Current Sensor Breakout Board Isolate Filter Resistance Capacitor Hall Effect Module

ACS714 5A 5V Current Sensor Breakout Board Isolate Filter Resistance Capacitor Hall Effect Module

Introduction: This current sensor is a carrier board or breakout board for Allegro's ACS715LLCTR-30A-T Hall effect-based linear current sensor, The sensor operates at 5 V and has an output sensitivity of 133 mV/A. The board ships fully populated with its SMD components. Feature: Designed for unidirectional input current from 0 to 5 A, but the sensor will provide meaningful feedback for currents as low as -1.5 A, and the robust IC can survive up to five times the overcurrent condition. Conductive path internal resistance is typically 1.2 m and the PCB is made with 2-oz copper, so very little power is lost in the board. Use of a Hall effect sensor means the IC is able to electrically isolate the current path from the sensor's electronics (up to 2.1 kV RMS) which allows the sensor to be inserted anywhere along the current path and to be used in applications that require electrical isolation. 80 kHz bandwidth that can optionally be decreased by adding a capacitor across the board pins marked 'filter'. High accuracy and reliability: typical total output error of 1.5% at room temperature with factory calibration, an extremely stable output offset voltage, and almost zero magnetic hysteresis. Automotive-grade operating temperature range of -40C to 150C. Package included: 1 x ACS714 5V 5A current sensor
