Light-Sensitive Resist Module with Automatic Brightness Control
Precision-engineered photosensitive sensor detects ambient light levels with ±5% accuracy, triggering automatic relay switching at customizable thresholds. High-grade ABS housing with flame-retardant (UL94 V-0) casing ensures durability in humid/dusty environments. Industrial-grade 5VDC relay supports 10A/250V AC loads – ideal for street lamps, greenhouses, or smart home automation. Zero-crossing detection eliminates arcing for silent operation. Ultra-low 2mA standby current with 0.5s response time. Gold-plated PCB traces prevent oxidation. IP65 waterproof optional for outdoor use. Batch pricing available for OEM/wholesale buyers. CE/FCC certified. Compatible with Arduino/Raspberry Pi via 3-pin GPIO.
