PRODUCT DESCRIPTION

Introducing a versatile solution for controlling higher voltages within your project: the single channel relay module. With the capability to activate devices or systems up to 250V AC and 30V DC, this module serves as a reliable switch for powering connected equipment.

Equipped with an onboard Bluetooth chipset, wireless control is at your fingertips. Simply use a Bluetooth-enabled scanning device, like a mobile phone, to trigger the relay. After pairing with the module (password: “1234”), you can effortlessly send signals to activate or deactivate the relay.

Visual feedback is provided through two onboard LEDs: a red power LED indicates the module’s status, while a green activation LED illuminates upon signal reception to trigger the relay. A blue LED for Bluetooth state indication and four red LEDs (D2, D3, D4, D5) indicate the relay’s status (ON/OFF).

Moreover, an audible click accompanies the relay’s activation, providing both audible and visual cues of operation.

This module offers a convenient and efficient way to incorporate remote control functionality into your project, whether it’s remotely controlling lights or triggering systems based on user-defined signals.
