Room Occupancy Sensors
Automatically detect occupancy in meeting rooms, offices or workspaces
Get accurate, reliable room utilisation data
Our wireless motion sensors detect and monitor the presence of people, in real time.
The small, battery-powered sensors simply stick to the ceiling, enabling you to detect presence and continually monitor room occupancy.

Product Features & Specifications
- Sends instant updates when occupancy is detected
- The sensor continues to monitor the workspace and send you regular updates on whether it’s occupied or not. Status updates can be configured between 10 minutes and 5 hours
- They can be configured to allow for short ‘absences’ from the desk
- GDPR and privacy-compliant solution: no images or personal information stored or transmitted
- No recurring fees. Access the data through your chosen platform, without any additional costs from Pressac
- Manufactured in the UK to high-quality and high-safety specifications, they are subject to rigorous testing procedures
- Passive infrared (PIR) sensor detects motion within 360-degree field of view, up to 6 meters distance
- Field of view will depend on ceiling height Based on a typical 2.5m ceiling height, approx. 64-degree detection angle resulting in estimated 5m detection
- Transmit data wirelessly and securely – using AES-128 encryption – via EnOcean wireless protocol, which uses internationally approved, licence-free ISM bands
- 868 MHz for Europe (RED)
- 902 MHz for North America (FCC) and Canada (IC)
- EnOcean Equipment Profile (EEP): A5-07-01
- Transmit up to 30 metres in buildings and 300 metres in free field
- Battery powered
- Battery life typically 5+ years
- 93 x 65 x 29 mm (approx)
Monitor room utilisation for better office space management
Instant room occupancy updates
The room sensors send an instant update when room occupancy is detected. You can configure ongoing occupancy updates every 10 minutes to 5 hours to maximise battery life.
Accurate, reliable workspace monitoring
The wide-angle, 360-degree radius PIR motion sensors detect passive infrared radiation (PIR) emitted by a person, so no interference from glass reflections. No cameras. Fully anonymous.
Real-time local or cloud data
Data can be sent securely to a local network or the cloud — via Ethernet, LTE (4G) or WiFi through an MQTT broker or ready connections to AWS and Microsoft Azure. No subscriptions or recurring fees.

Room Occupancy Sensor FAQs
Pressac’s room occupancy sensors use passive infrared (PIR) technology to detect motion. They sense changes in infrared radiation within a 360-degree field of view, typically covering a 6-meter diameter area when mounted on a 2.5-meter-high ceiling. Upon detecting movement, the sensor immediately sends a wireless signal indicating presence.
Our room occupancy sensors are designed for easy installation. They can be mounted on the ceiling using the provided screws for permanent installation or sticky pads for temporary setups. Proper positioning ensures optimal detection, with the primary detection zone offering the most accurate sensing.
No. Our room presence sensors are pre-configured to detect motion out of the box. However, users can configure settings such as absence timeout and repeat telegram intervals using Pressac’s ProComm software.
Our sensors are battery-powered with an estimated battery life of over 5 years under typical usage conditions. Battery life can vary based on reporting frequency and environmental factors. A USB-powered variant is also available.
Data is transmitted wirelessly using the EnOcean protocol over license-free ISM bands (868 MHz for Europe). The sensors can send data to a local network or cloud platforms via Pressac’s smart gateway, which supports Ethernet, LTE (4G), or WiFi connections.
Yes, data from our room occupancy sensors can be integrated with various cloud platforms. The smart gateway publishes data in JSON format using MQTT protocol, allowing integration with platforms like AWS, Microsoft Azure, IBM Watson IoT, Google Sheets, or Node-RED applications.
Yes, the reporting frequency is configurable. Users can set the interval for repeat occupancy telegrams between 10 minutes and 5 hours to balance data granularity and battery life. These settings can be adjusted using the ProComm software.
The absence timeout is the period the sensor waits after the last detected movement before sending an "absence" signal. This duration is configurable between 2 and 60 minutes, allowing customization based on room usage patterns.
Yes, our sensors support secure communication. When secure mode is activated, all device communications are encrypted using AES-128 encryption. Users can toggle secure mode by pressing the sensor's button for at least 10 seconds.
Yes, our room occupancy sensors are designed with privacy in mind. They do not capture images or personal data, ensuring anonymity. The company adheres to the UK GDPR and the Data Protection Act 2018, implementing appropriate technical and organizational measures to protect data.
No, there are no ongoing costs associated with using our room occupancy sensors. Users have full control over their data and can access it through their chosen platform without any additional fees.
How do our room occupancy sensors work?
Our occupancy sensor technology is system agnostic, meaning the data from our sensors can be used in any way you need and can be easily accessed and integrated in near real-time.
There are different options to choose from, making it easy to get your data in the way that’s right for you.
