Introduction to the PS05-Pro Recessed Ceiling Presence Sensor

In today’s smart home solutions and automated electrical systems, optimizing lighting systems and saving electricity are always important priorities. Therefore, the high-tech PS05-Pro recessed ceiling presence sensor was developed. This is a premium new-generation power management device from Kawasan.

The device has been significantly upgraded with dual technology combining PIR and 24GHz Radar. This combination provides highly accurate motion detection. The device supports continuous human presence detection even when a person is standing still. To explore more high-quality smart solutions, you can refer directly to the category KAWASAN Smart Electrical Products.

This smart switch operates based on a 2-step data management mechanism:

• Step 1 – PIR infrared circuit activates: When body-heat movement is detected entering the area, the infrared sensor (PIR) immediately turns on the light, fan, or electrical device.

• Step 2 – 24GHz Radar circuit maintains the power supply: After the connected load has been successfully turned on, the high-frequency presence sensor continues operating continuously. The sensor closely detects the breathing and heartbeat of the person sitting in the room. This feature helps keep the light steadily ON without turning off unexpectedly.

Thanks to this smart and sensitive combined mechanism, the PS05-Pro is not falsely triggered through thick walls. It completely eliminates the drawback of detecting through glass or wooden partitions found in older microwave sensor models. This helps prevent unwanted light activation in the building. The product is especially suitable for bedrooms, bathrooms, or offices.

3. Outstanding Features

Dual Technology for False Alarm Prevention (PIR + 24GHz Radar)

• PIR only turns on the light when a person actually enters the area.
• The 24GHz Radar then maintains extremely high sensitivity to detect human presence even without movement → the light stays ON whenever someone is present.

This solution completely eliminates situations such as:

• The light turning on because someone walks outside the door,
• Interference through walls or glass (a drawback of microwave sensors).

No Detection Through Glass – Wood – Plasterboard

PIR detects from inside → the sensor only turns on the light when a person actually enters the room.

Sensitivity Adjustment (SENS)

• “+” → wide 6m range for large rooms
• “–” → small 2m range for small rooms, helping reduce unwanted activation

Day/Night Detection (LUX)

• 24/7 operating mode
• Or only operates in dark environments (<3 LUX)

Automatic Time-Delay Reset

If movement is detected during the waiting period, the sensor automatically resets the countdown time → ensuring stable and accurate operation.

Smart Start-Up

The device requires a 30-second “warm-up” period before operation to stabilize the sensor.

IP54 Water Resistance – Suitable for Bathrooms

Helps prevent moisture from interfering with the sensor.

4. Applications

PS05-Pro is designed for areas that require high sensitivity inside – prevention of outside activation, especially:

• Household and hotel bathrooms

• Meeting rooms, waiting rooms
• Offices, workspaces

• Bedrooms (keep the mechanical switch to turn the system off while sleeping)

• Entrances near busy hallways

• Spaces with glass doors, wooden partitions, or thin walls

Benefits of Using PS05-Pro:

• Does not turn on the light when someone walks outside the hallway.
• Does not turn off the light when a person remains still (reading, working, showering, changing clothes, etc.)
• Saves electricity while increasing convenience and safety.

Special Application: Can be installed for air conditioners (with an additional KWC1-25A mini contactor) in children’s rooms, meeting rooms, bedrooms, hotel rooms, and offices. When no one is in the room, the air conditioner will turn off after 10 minutes. This helps prevent electricity waste caused by forgetting to turn off the air conditioner (each air conditioner can save approximately VND 300,000–500,000/month).

Note: For Inverter air conditioners, turning the unit ON/OFF does not increase electricity costs or affect the lifespan of the air conditioner. When using the sensor with an air conditioner, keep the air conditioner in ON mode so that it automatically starts when power is supplied, without needing to restart it using the air conditioner remote control.
