Designed as a \u003cstrong\u003elow-level trigger\u003c\/strong\u003e SSR board, it activates when the control signal goes low, simplifying integration with common 5V logic setups. The single-channel design is ideal when you need one GPIO-controlled on\/off output for smart home builds, test benches, lighting control, and embedded automation tasks without the clicking of a mechanical relay. It is a practical relay module for microcontroller and single-board computer projects where silent solid state switching is preferred for frequent or responsive control.\u003c\/p\u003e","brand":"ShillehTek","offers":[{"title":"Default Title","offer_id":52709886755103,"sku":"NA167","price":5.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/4340\/8415\/files\/5v-1-channel-ssr-module-angle-01.jpg?v=1786597389","url":"https:\/\/shillehtek.com\/products\/solid-state-relay-1ch-5v-active-low","provider":"ShillehTek","version":"1.0","type":"link"}
