Summary
The OS11 Z-Wave occupancy sensor uses 24 GHz Doppler technology to detect human presence, including subtle movements and breathing. It integrates smoothly with Z-Wave controllers to automate lights, alarms, and other devices. Offering reliable detection up to 8 meters and fast response, it works well in various environments and supports secure, low-power operation with direct device activation via an internal relay.
Advanced Z-Wave Human Presence Sensor
This advanced Z-Wave occupancy sensor uses 24GHz millimeter-wave Doppler technology to accurately detect human presence, distinguishing between motion, minor movements, and even breathing patterns. It interacts seamlessly with lights, blinds, fans, air conditioners, security alarms, and other electrical appliances through your home automation network. Suitable for homes, holiday rentals, hotels, offices, and various other environments, it remains unaffected by temperature, humidity, noise, airflow, dust, or light conditions.
Compatible with any Z-Wave network and certified devices, the sensor also features an internal relay that allows direct activation of connected equipment without additional controllers.

Detection Range and Operating Areas
The sensor features a horizontal beam angle of up to 80° (3 dB) and a vertical beam angle of up to 85°, providing high accuracy and a wide detection range. Presence or absence is detected with a switching time of under 0.5 seconds.
The maximum detection range for movement presence covers a diameter of 5 to 8 meters, while minor presence detection extends to a diameter of 3 to 4 meters.

Technical Overview: OS11 Presence Sensor
The OS11 model uses 24 GHz Doppler radar technology and communicates via Z-Wave Plus (800 series) with S2 Security. It operates on 90–250 V AC, with an optional 12 V DC version available. The relay output supports up to 5 A.
Detection ranges include breathing within 2–3 meters, micro-motion within 3–4 meters, and large motion within 5–8 meters. It has a detection angle of up to 85° vertical and 80° horizontal, with a response time under 0.5 seconds.
RF transmission power is up to +13 dBm with ultra-low emissions. The device works in temperatures from –10 to +50 °C and humidity levels of 20–85% RH (non-condensing). Its dimensions are 85 × 85 × 41 mm.
