The LT-M9500 is air temperature and humidity, infrared CO2, and TVOC sensors are internally configured with MEMS specialized modules for measuring air temperature and humidity.
The LT-M9500 is air temperature and humidity, infrared CO2, and TVOC sensors are internally configured with MEMS specialized modules for measuring air temperature and humidity.
They can also accurately measure CO2 sensor data using the NDIR principle. The TVOC uses an imported semiconductor measuring probe, which can measure gas concentrations above 0.01PPM.
It has higher sensitivity, especially for volatile gases such as formaldehyde, benzene, and toluene, which have a greater impact on human health, and can be used for qualitative measurement of air quality.
Using LoRaWAN wireless communication technology that is compatible with the standard LoRaWAN protocol,it provides flexible and convenient networking, and can be widely used in the field of atmospheric environmental monitoring in the Internet of Things, such as intelligent breeding, smart homes, factories, and shopping malls.
Using 1 section 2# lithium battery powered, with sleep wake up function, long battery life, no wiring, construction convenient.Import CO2 low power probe, unique NDIR dual channel measurement technology immune to outside interference, accurate measurement, long battery life.
