8 Channel relay board for your Arduino or Raspberry PI - 12V
A general purpose 8 SPDT channel relay board (power supply 12VDC) for switching high-current electrical loads (both AC and DC) siuch as motors, lights, pumps, contactors and more. With this relay board, any logic-level signal from 3V up to 30V can be used to activate a relay (it may be controlled direclty by microcontroller TTL logic as well). It can be used successfully for example with PIC,AVR,ARM microcontroller, Raspberry PI, Arduino outputs and other.

Wi-Fi Wireless Relay Board 8 Channels - Web, Telnet, HTTP API, E-mails
This is WiFi Wireless 8 channel SPDT relay module (board) for remote management and control with Virtual Serial Port, TCP/IP, Web, HTTP API, Telnet and serial commands access. It has 8 SPDT Relays, 8 digital inputs, 8 analog inputs and one UART port. Inputs can be adjusted to control relays (standalone work). Also inputs of one controller can control outputs of another over the LAN/WAN (box-to-box mode). It can send E-mails on inputs change as well. Suitable for remote control, home automation, data acquisition, sensor processing, alarm systems, PLC applications. Works with Home Assistant, Domoticz and OpenHAB home automation systems as well as with Node-RED IoT platform. Now with FREE Android and iOS App!
