1. Carbon dioxide detector: split probe sensor external probe sensor, greenhouse planting CO2 alarm. 2. Large screen display, intuitive reading: large LCD display clearly shows carbon dioxide, temperature, relative humidity and real-time clock. 3. Carbon dioxide concentration automatic control: carbon dioxide affects the photosynthesis of vegetables, installing carbon dioxide sensors in the greenhouse can ensure that the carbon dioxide concentration is insufficient in the case of timely replenishment. 4. High-precision probe sensor: Split probe sensor external probe sensor, highly sensitive measurement of carbon dioxide content. 5.
