Module Relay Gravity 1 kênh 5A

The DFRobot Relay Module is a standard relay designed to establish a connection between external circuits or modules and controller boards. It finds common applications alongside Arduino in areas such as home lighting, high-power appliances, and various other devices. Its modular design allows for seamless integration with controller boards, ensuring ease of use. This relay module integrates a status LED, enabling visual indication of its activation or deactivation state. It can be controlled through the digital IO port with a simple HIGH or LOW on Arduino compatible boards. Other boards will require the same voltage level. This module is also suitable for controlling electromagnetic valves, lighting fixtures, motors, and other high-current or high-voltage equipment.

If you intend to use this relay coil with 3.3V controllers such as ESP32 and Raspberry Pi Pico, you can consider exploring this relay that supports 3.3V operation.

Relays are typically employed for low-frequency switching applications, such as controlling the on/off operation of solenoid valves or lighting fixtures. However, if you want to adjust the brightness of a light or regulate the speed of a water pump using PWM, I recommend using the Gravity: MOSFET Power Controller. This MOSFET controller does not support AC voltage and cannot isolate high voltages exceeding 30V. Nevertheless, it allows for the smooth power control of loads within the voltage range using a PWM signal with a frequency of 1kHz.
