In this post we are reviewing the ESP-01 Wi-Fi Relay Module. It is one of the cheapest smart switches you can purchase currently for making smart home, internet of things, and other wireless do it ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

In electronic and industrial automation systems, relay modules play a crucial role by allowing low-power control signals to switch high-power devices. Selecting between a 5V relay module and a 12V ...

Designed specifically to comply with updated ISO 13849 Safety Category 2 requirements, this safety relay module helps users economically apply better and more appropriate safety measures. IDEC ...

Someone has invented a way to add Wi-Fi to a standard Arduino Uno, by proposing a module that drops into the DIL socket normally reserved for the ATmega328 – it will not work with Unos that have a ...

The relay repeater module accepts single contact closure inputs from logic solver trip outputs including the company's STA Safety Trip Alarm and the SPA2 Programmable Limit Alarm Trip. With three ...

Addressing the requirements of power switching applications, the ADAM-6066 relay-output module includes Ethernet connectivity, an embedded web server for remote monitoring, and support for Modbus/TCP ...

[Andy] needed a cheap Internet connection between a data-gathering Arduino and his home server. An Ethernet shield would suffice, but he couldn’t run CAT5 to the Arduino’s location. Wireless shields ...

Fire-Lite Alarms has added a wireless relay module to our SWIFT® line of devices. The SWIFT® relay module expands wireless application opportunities providing the ability to activate a remote power ...

Raspberry Pi may be grabbing the headlines and Arduino board may be developing a big following, but arguably the blueprint for the embedded design platform was created by TI’s BeagleBoard and ...
