Compact CO2 Detector with Alarm Function

A dedicated CO2 air quality detector engineered for agricultural and indoor cultivation environments. It measures CO2 in the range of 400–5000 ppm with 1 ppm sensitivity, and concurrently monitors ambient temperature and relative humidity. Its 2.8-inch backlit LCD presents all three parameters clearly, supported by a dynamic colour-coded ring that reflects current CO2 conditions. Weighing only 165 g and measuring 140 × 125 × 42 mm, it is highly portable and powered via USB-C. With 240–360 minutes of standby time and automatic detection from startup, it requires no calibration. Suitable for greenhouse management, educational labs, warehouse air monitoring, and home-based horticulture applications.
