4 CHANNEL BLUETOOTH RELAY SHIELD
4 channel Bluetooth relay shield for Arduino. Wirelessly control AC/DC loads for home automation and IoT projects.
Description
The 4 Channel Bluetooth Relay Shield is a smart wireless control module designed for Arduino and microcontroller-based automation projects. Featuring built-in Bluetooth connectivity, it allows users to control up to four high-voltage AC or DC loads wirelessly using a smartphone, tablet, or Bluetooth-enabled device. Each relay can be independently switched, making it ideal for home automation, smart appliances, robotics, and IoT applications. The shield’s plug-and-play design simplifies installation and reduces wiring, while ensuring reliable and safe operation.
