5VDC 10A Single Channel Relay Module compatible with arduino
RM5.00DescriptionNote: From February 2020 onwards, the module comes with a logic low circuit.
The Relay breakout board is a convenient board to be used with 5V microcontrollers such as SK40C, SK28A, Arduino, SKds40A, SK18B. You can easily use 5V signal to control the relay. Three inputs:
- VCC = 5V is needed
- GND = Common Ground, 0V
- IN = Control signal need to be
5V0V to activate the Relay (Active Low)
The relay terminals (COM, NO, and NC) are brought out using a 3-way screw terminal. On-board relay is rated at 10A. It can be used in many applications: controlling high voltage, high current loads such as motor, solenoid valves, lamps, and AC load. It also comes with 2 LEDs to indicate the status power (VCC) and the status of the relay.
Note: This is an
active-highactive-low device, which means logichigh (5V)low (0V) at pin IN will trigger the relay. -
HC-SR04 Ultrasonic Distance Range Finder Sensor for Arduino
RM5.00DescriptionIf you’ve been searching for distance measurement and object detection sensors at a rock-bottom price, look no further! This legendary HC-SR04 ultrasonic sensor is your perfect choice. It offers excellent range accuracy and fairly stable readings at a very low cost. It requires two digital I/O pins (an output pin and an input pin) to interface with it.
An ultrasonic sensor is created based on the principle of echolocation used by animals like bats and dolphins. Since the ultrasonic sensor uses sonar to determine the distance to an object, its operation is not affected by sunlight, spotlight, and object’s surface color which will affect the readings of any infrared distance sensors. However acoustically soft materials such as clothes can be difficult to detect.
