| S0=1 (default) | Serial UART mode, Pin2 is TX, Pin3 is RX, TTL level |
| S0=0 (when connected to GND) | MCU_IIC mode, Pin2 is SCL, Pin3 is SDA |
(2) PinB (S1) uses only the sensor chip ME280+MAX44009 mode to select whether the MCU participates in data processing
| S1=1 (default) | MCU+ chip mode, Pin7, Pin8, please do not have any connection |
| S1=0 (when connected to GND) | Chip mode only, Pin7 is the chip SCL bus, Pin8 is the chip SDA bus |

Data analysis of computer software
Name: 4 in 1 weather station module(light intensity + temperature and humidity + atmospheric pressure module)
Model: GY-39
Using chip: MAX44009+BME280+MCU
Power supply: 3-5v
Module size: 24.3*26.7mm
Communication mode:MCU_IIC/MCU_Serial / sensor chip IIC bus
Introduction:
GY-39 is a low cost, air pressure, temperature and humidity, light intensity sensor module. The working voltage is 3-5V. The power consumption is small, and the installation is convenient. The working principle is that the MCU collects various sensor data, performs unified processing, and directly outputs the calculated result. This module has two ways to read data, namely serial UART (TTL level) or IIC (2 line). The baud rate of the serial port is 9600bps and 115200bps, configurable, continuous, and two output modes are requested, and the settings can be saved after power down. It can adapt to different working environments, and connect with single-chip computer and computer. The module can also set a separate sensor chip operating mode. As a separate sensor module, the MCU does not participate in data processing. Provide , 51, stm32 MCU communication program, does not provide schematic and internal MCU source code. This GY39 module also gives Android mobile phone software app to view data, and supports wifi LAN connection, mobile phone and computer display data at the same time.
