Automatic Stair Step Lighting Solution — PIR Staircase LED PCB
SOLUTION DEFINITIONAn automatic stair light solution uses motion sensors and an MCU to illuminate stair strips step-by-step as people approach, then fade them out after a delay. It supports PIR and microwave radar sensing plus master-slave cascade wiring, and is widely deployed in duplex homes, villas, hotels and offices.
Pain Points We Solve
- Stair lights are either always-on wasteful, or you fumble for switches in the dark
- Off-the-shelf controllers have short sensing range and false triggers from pets
- Multi-step cascade wiring gets messy and expensive to install
- Hotel projects need dimming, CCT control and fire-alarm linkage most solutions lack
Key Features
Precise SensingPIR or 5.8GHz radar, 3–8m range adjustable, lux + time gating against false triggers
Step-by-step Effects16 built-in animations: cascade, flow, breathing, fade — speed adjustable
Cascade ControlMaster-slave bus strings up to 32 steps on one signal line
Dimming & CCT0–100% dimming, 2700K–6500K tunable (dual-white strips), remote/app set
Smart Delay10s–10min hold time, gentle fade-out, auto night-light mode
Project ReadyDry-contact fire linkage, RS485/KNX interface for hotel & BMS projects

FAQ
What does a 16-step system cost?
For 16 steps + master, BOM cost lands around USD 45–90 depending on strip power and options. We support full BOM quoting; factory-direct pricing is sharper.
Will my cat trigger the lights?
Radar versions support sensitivity and height gating to filter targets below 40cm — measured false-trigger rate < 3%.
Is wiring complicated for retrofits?
Standard setup uses one 4-wire bus through the staircase with plug-in slaves; a battery slave option enables zero-wiring retrofits.
Does it work with smart home ecosystems?
Yes — BLE/Zigbee/WiFi module sockets for Mi Home, Tuya and HomeKit; project build supports RS485 BMS integration.
Can it meet hotel fire-code linkage?
The project master includes dry-contact input and forced-on mode for emergency lighting compliance, with project-level customization.
