Arduino Sensor And Modules

1 Channel 5V Arduino Relay Module for Arduino PIC AVR DSP ARM. Single-channel relay, a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, and so on can control it. The 5V relay module circuit, each needs a 15mA-20mA driver current and is equipped with a high current relay: DC 30V / 10A, AC 250V / 10A. This one channel module has a standard interface that can be compatible with a microcontroller. This 5V Arduino relay module has on the high level and low level-triggered mode, friends who do not understand, have a look high-level trigger refers to the signal voltage between input and trigger, can be understood as a signal input with VCC cathode short-circuit triggered away. Low-level trigger refers to the signal voltage between the input terminal and Earth OV trigger, which can be understood as the signal input terminal and the GND negative electrode short circuit triggered away 1-channel relay module connection.

This is a 5V 4-channel relay interface board, and each channel needs a 15-20mA driver current. This 4-way relay module can be used to control various appliances and equipment with a large current. This four-channel relay module is equipped with high-current relays that work under AC250V 10A or DC30V 10A. 5 volts relay driver module has a standard interface that can be controlled directly by the microcontroller. This relay module board allows a wide range of microcontrollers such as Arduino, AVR, PIC, ARM with digital outputs to control larger loads and devices like AC or DC Motors, electromagnets, solenoids, and incandescent light bulbs.

This 6 Channel Relay Module (with light coupling) 5V module meets the safety standard as control areas and load areas have the isolation groove. Optical coupling isolation module. The triggering of the 6 Channel Relay Board is reliable, more stable. The double FR–4 circuit board design, high-end SMT process. Arduino 6 Channel Relay Module has power and relay operation instructions. Relays terminals (C, NC, NO) are accessible through screw terminals which makes wiring up the board very easy. The inputs of the 6 Channel Optocoupler Relay Module are isolated to protect any delicate control circuitry. A wide range of microcontrollers such as Arduino, AVR, PIC, ARM, and so on can control it. The use of such a high-voltage relay eliminates the risk of heating up the relay as an electromechanical relay limits the current consumption in accordance with a voltage rating.
