Perfect for dimmable incandescent lights, small fans, pumps, air purifiers, and low-power heating elements. True voltage control, not just on\/off switching.\u003c\/li\u003e\n\u003cli\u003eULTRA-COMPACT DESIGN – Tiny footprint (60 × 20 × 20 mm) fits easily into small enclosures and tight spaces. Ideal for DIY smart switches, lamp controllers, and space-constrained automation projects where larger modules won't fit.\u003c\/li\u003e\n\u003cli\u003eARDUINO \u0026amp; ESP32 COMPATIBLE – Supports 3.3V, 5V, and 12V logic levels for universal microcontroller compatibility. Works with Arduino, ESP32, ESP8266, STM32, Raspberry Pi, and more. Ready-to-use rbdimmerESP32 library simplifies coding with example projects.\u003c\/li\u003e\n\u003cli\u003eSMART HOME INTEGRATION – Direct compatibility with ESPHome for Home Assistant, Tasmota firmware, and custom automation platforms. Build voice-controlled lighting, scheduled operations, and energy-saving routines through your preferred smart home ecosystem.\u003c\/li\u003e\n\u003cli\u003eSAFE OPTOCOUPLER ISOLATION – Complete electrical separation between high-voltage AC and low-voltage control circuit protects your microcontroller. Zero-cross detection output enables precise timing synchronization for flicker-free dimming.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch1\u003eOverview\u003c\/h1\u003e\n\u003cul\u003e\n\u003cli\u003eOperation Mode : ON-ON-ON\u003c\/li\u003e\n\u003cli\u003eCurrent Rating : 4 Amps\u003c\/li\u003e\n\u003cli\u003eOperating Voltage : 120 Volts\u003c\/li\u003e\n\u003cli\u003eContact Type : Normally Closed\u003c\/li\u003e\n\u003cli\u003eConnector Type : Clamp\u003c\/li\u003e\n\u003cli\u003eBrand : Generic\u003c\/li\u003e\n\u003cli\u003eSwitch Type : TRIAC\u003c\/li\u003e\n\u003cli\u003eTerminal : Screw\u003c\/li\u003e\n\u003cli\u003eMaterial : PCB\u003c\/li\u003e\n\u003cli\u003eItem dimensions L x W x H : 1.97 x 0.63 x 0.39 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"SmartHomeValueHub","offers":[{"title":"Default Title","offer_id":46755128115389,"sku":"B0G33DHKYM","price":13.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0755\/9344\/9661\/files\/515XaxfOrtL._SX522.jpg?v=1778233226","url":"https:\/\/smarthomevaluehub.com\/products\/b0g33dhkym","provider":"SmartHomeValueHub","version":"1.0","type":"link"}
