What is a sensor-light sensor?
A sensor-light sensor is the detection module inside a luminaire that switches lighting on and off from motion. It is either a 5.8GHz doppler (microwave) type that works through the cover, or a PIR type that reads body-heat infrared. How 5.8GHz doppler compares with PIR →
BIO Electronics designs and manufactures these sensors in-house for parking, factory and ceiling-mount luminaires. See the sensor light guide for how the detection types compare.

Which sensor should you choose?
The right answer depends on the installation environment. Here is how our three flagship products compare.
Sensor must hide behind the cover → 5.8GHz doppler
Radio waves pass through plastic and glass, so the sensor can be fully embedded inside the luminaire — clean looks, no temperature sensitivity.
Rows of fixtures (parking, factory) → AI group control
JA58K1(G)-3123 lights fixtures ahead of a moving vehicle using BLE Mesh and self-learning groups.
Short range, cost-sensitive (stairs, corridors) → PIR
BIO-24AD-IRF is a smart PIR controller with 2–8 m detection, 10–90 s hold, 0–30% standby PWM and an optional 40-group RF network.

Three things to check before replacing a sensor
If you are keeping the existing luminaire and swapping only the sensor module, these three points decide compatibility.
1. Cover material
5.8GHz doppler radio waves pass through plastic and glass, so the sensor can be fully concealed inside the cover. Metal covers shield the signal — use an exposed PIR type instead.
Hidden sensor luminaires explained →2. Required detection range
For wide areas such as parking garages and factories, use the 5.8GHz doppler modules (0.3–7 m radius, 15 m linear, 120°). For stairs, corridors and entrances, the 2–8 m PIR controller is the better fit.
Compare doppler vs PIR →3. Mechanical and electrical fit
Compact ceiling-mount fixtures take the 18 × 18 mm BIO58K1-1818. Hold time (10–90 s) and standby PWM (0–30%) can be tuned to your existing driver. All models are KC-certified.
