HALO Smart Sensor 3C-PC

Smart Building Sensor • Air Quality & Vape Detection • Privacy-Safe People Counting • Panic-Button Ready

The HALO Smart Sensor 3C-PC is an all-in-one safety, air-quality, and occupancy monitor for spaces where privacy matters — restrooms, locker rooms, hotel lobbies, schools, and corporate floors. It uses heat-sensing technology to count people without capturing video or personal data, while watching for vape/THC, CO, CO2, particulates, NO2, temperature, and humidity in real time. Surface-mount installation gets it live fast, and it pairs naturally with a two-way radio fleet so your team can respond the moment an alert fires.

Compatible Radios

The HALO 3C-PC is a standalone smart sensor that reports through the HALO Cloud dashboard via email and mobile push — it is not tied to a specific radio model. For an alert-to-radio response workflow, it works alongside any of our business two-way radios. Want to connect HALO alerts to your team's radios or build a complete safety setup? Call 1-800-984-1534 or contact our radio experts and we'll spec the right pairing for your site.
