ESP 32 GENERAL PURPOSES RELAY BOARD
This board has some useful features:

• 4x SPDT Relays with independent power supply
• 5x Solid State Relays
• 6x GPIO pin connected to 4x PWM pin and 6x ADC pin.
• 1x I2C port
• 2x UART port (1x for debug and programming)
• I2C Real Time Clock Module
• I2C Oled Display
• 3x buttons
• 1x RGB Led
• 1x buzzer
• 1x SDCard slot

You can use this board for any project like:

• IoT home automation

You can use the relays or solid state relays for controlling your home equipment based on time or other conditions.

• Smart incubator

You can add sensors like DHT11/DHT22 for humidity and temperature monitoring or an LDR circuit that is connected to the GPIO pin then you can use relays to control the heater or fan.

• Smart greenhouse

You can add sensors like soil sensors and DHT11/DHT22 for humidity and temperature monitoring that is connected to the GPIO pin then you can use relays to control the water pump or heater and fan.

• Data logger

You can use the Micro SDCard slot to record all activity and your sensor data.

• ETC...
