ES32 32-Channel PIR Motion Sensor Stair Light Controller

The ES32 PIR Sensor Stair Light Controller is a 32-channel stair lighting controller with dual PIR motion sensing and a built-in daylight sensor. As someone approaches, the treads illuminate one by one in the direction of travel, then fade off after a set delay. In daylight it stays idle.

Unlike single-output controllers, the ES32 drives 32 independent constant voltage channels — one per step, at up to 1A each — so every tread is switched individually with ordinary single-colour LED strip. Two SPI outputs run alongside for an addressable accent strip on the handrail or stringer.

Key Features

• 32 constant voltage output channels, 1A per channel — one step per channel with standard single-colour strip
• Two SPI (TTL) outputs for addressable RGB pixel strip, run simultaneously with the step outputs
• Bi-directional PIR sensing detects approach from either end of the staircase
• Built-in daylight sensor with adjustable threshold (10–200 lux, or off)
• Four work modes: White Step, Colour Flow, Colour Step, and White Step + Colour Flow
• Two controllers can be cascaded for staircases over 32 steps
• Push switches can be wired in as a manual trigger, as an alternative or supplement to the PIR sensors
• Individual channels can be disabled in software if a strip run or output fails
• Over-heat and short circuit protection, with a built-in self-test function
• Two switch-off behaviours: all steps together, or sequentially from the far end
• Off-delay adjustable from 5 seconds to 10 minutes, or set to stay on
• OLED display with three-button setup — no app or programming required
• Wide 5–24V DC input suits 12V or 24V LED systems

Four Operating Modes

White Step — single-colour strip on each tread, 8 to 32 steps. Four sequence patterns: one-by-one, rolling five-step window, inverse one-by-one, or all on.

Colour Flow — one or two straight runs of addressable pixel strip, up to 960 pixels, with 12 colour effects.

Colour Step — addressable pixel strip laid step by step, up to 160 steps at 2–120 pixels each (960 pixels total).

White Step + Colour Flow — the common configuration: single-colour treads plus a continuous colour accent run along the stringer or handrail, both triggered together.

Specifications

Sizing Your Installation

Strip required for the treads = (number of steps × step width) ÷ roll length. A 20-step staircase at 1.5 m per tread needs 30 m of strip — six 5 m rolls, cut to 1.5 m sections.

Your power supply must match the strip voltage and be rated at least 1.25× the total connected load. For 180W of strip, specify a 225W supply or larger.

Installation Notes

• Mount PIR sensors at least 700 mm above floor level, with the sensing holes perpendicular to the direction of travel
• Keep sensors clear of direct sunlight, air conditioning outlets, heaters and sources of moving warm air
• The daylight sensor head must see ambient light — don't conceal it in shade
• Connect step strips in channel order and observe polarity
• The upstairs PIR connects to DW PIR INPUT; the downstairs PIR connects to UP PIR INPUT
• If the SPI strip runs at a different voltage to the step strip, power it from a separate supply
• Use 0.3 mm² or heavier wire to extend single-colour runs, 0.8 mm² or heavier for SPI

A 5–24V DC constant voltage LED driver, LED strip and connecting wire are required and sold separately. Use our Power Supply Calculator to size the driver, or get in touch and we'll spec the whole run for you.
