                        With Display Board ID: 1677424

                        Overview :

                        The SM300D2 seven-in-one sensor module is a cost-effective digital serial output sensor module. It uses both RS485 data bus and UART serial port TTL level output modes, collecting CO2, formaldehyde, TVOC, laser PM2.5, PM10, temperature , Humidity in one. It can carry out real-time comprehensive detection of the environment in which it is located, and has good stability.

                        Features :

                        ● Simultaneous output of carbon dioxide, formaldehyde, TVOC, PM2.5, PM10, temperature, humidity seven sets of data
                        ● High sensitivity and stable data
                        ● At the same time, it adopts two output modes of RS485 bus and UART TTL level, which is convenient for customers to choose and use independently.
                        ● The temperature is accurate to 0.1 ℃, and the humidity is accurate to 0.1% RH
                        ● Automatically output these seven sets of monitoring data via RS485 interface every second
                        ● With power supply anti-reverse protection function

                        Application :
