QingPing LoRaWAN CO2 Monitor with Temperature & Humidity Display

The QingPing LoRaWAN CO2 Monitor uses NDIR sensing to measure CO2 and pairs it with temperature and relative humidity—three signals that, together, tell you whether a room is properly ventilated and comfortable. Values are visible on the display, while LoRaWAN lets you collect data across floors or multiple buildings without relying on Wi-Fi at every location.

Where it really shines is in spaces where occupancy changes quickly and “guessing” doesn’t work: in meeting rooms, CO2 reveals when air quality drops and productivity starts to suffer; in gyms and studios, it helps keep the environment consistent during peak classes; in clinics and waiting areas, it supports healthier indoor conditions by highlighting ventilation gaps. It’s also useful for hotels and conference venues where you want to avoid both under-ventilation and unnecessary HVAC runtime—data makes those patterns obvious.

The built-in buzzer can provide an immediate local prompt when thresholds are exceeded, and notifications can be triggered when readings hit limits, the device goes offline, or the battery is running low.
Practical note: it’s not recommended for long-term use in environments with humidity above 90%.
