5V Relay Module 1-Channel (KY-019)
Recommended for Arduino starters!
14 in stock
This relay module is designed to control small electrical objects such as motor, pump, lamp, and other devices that require high voltage and high current to operate. The logic level of this module is positive, which means you need to feed a HIGH (3 – 5V) signal to the Signal ‘S’ pin to activate the relay switch. Feed a LOW (0V) signal to the input pins to deactivate the relay switch.
Be very careful when handling the relay with AC power source, mishandling can cause electrocution, short-circuits and unwanted consequences!
