RoomSense IQ allows smart-home enthusiasts to automate household infrastructure based on their physical presence. It makes your heating, cooling, ventilation, lighting, entertainment, air-filtration, home-security, and emergency-alert technology—among other essential services—smarter, easier to manage, and more efficient. Create a truly harmonious living environment that knows where you are, and has a pretty good idea what you’re up to, but does not share that information with a third party unless you tell it to. You remain in control without having to manage so many…controls.

If indoor air-quality monitoring isn’t on your list of priorities for home-automation, it probably should be. Poor air quality can lead to respiratory issues such as asthma and allergies, and carbon-monoxide buildup can be life threatening. Our ClimateSense Pro hardware expansion module (sold separately) integrates seamlessly with RoomSense IQ to monitor indoor-climate conditions like temperature, humidity, CO₂ levels, smoke, and other such indicators. ClimateSense Pro provides actionable insights to help you keep your living and working spaces healthy, comfortable, and productive.

Smart Presence Detection Thanks to mmWave Radar & PIR sensors

RoomSense IQ is built around the the powerful ESP32-S3 SoC, which supports Wi-Fi connectivity and enables seamless integration with existing IoT networks and other systems that facilitate realtime data transmission and remote monitoring. It utilizes mmWave radar to detect presence and movement, within a 120° arc, at ranges of up to six meters. To ensure precise detection and reduce false positives, RoomSense IQ is also equipped with a passive infrared (PIR) sensor that filters out non-human activities such as spinning fans and wind-blown curtains.

By accurately measuring ambient illumination, the built-in light sensor can automatically adjust lighting conditions to optimize energy consumption and create a more comfortable environment. A multi-purpose RGB LED conveys at-a-glance status information, and a USB Type-C interface draws power and handles serial communication. Finally, our ball-mount enclosure allows you to orient the sensors in any direction. Maximize coverage by positioning RoomSense IQ in a corner of the room it’s monitoring or accommodate unique deployment with custom placement.

Don’t Compromise on Your Family’s Well Being

We designed our ClimateSense Pro hardware expansion module (sold separately) to help you maintain optimal indoor climate conditions. It provides unprecedented insights into your environment by monitoring temperature, humidity, dew point, and crucial contaminants such as airborne chemicals (TVOC), carbon dioxide (CO₂), carbon monoxide (CO), dust, and smoke. This level of comprehensive monitoring allows for the intelligent control of purification, humidification, and ventilation systems, which can reduce your energy consumption while enhancing the comfort and safety of your family members, coworkers, or tenants.

Introducing SightSense, our Web-Based Dashboard

SightSense is a web application that adds a whole new layer to this powerful ecosystem by giving you an intuitive interface through which to manage the various RoomSense IQ sensors. Unlike some other platforms that tend to be too complex or too limited (or both), SightSense is equipped with basic, easy-to-use settings and advanced configuration options. Examples include CalSense for baseline calibration, MoveSense for movement classification, ProxiSense for proximity-based automation, and BedSense for sleep optimization. All together, these features give you exceptional control over the spaces you inhabit.
