Description On Board Sensors: BMP280 Pre-mounted on the board. BMP280 -> Barometer, altitude: Barometric pressure measurement range: 300 to 1100 hPa (half pascals) Pressure measurement error: ±1hPa Resolution: 0.16Pa BMP280 -> Temperature: Temperature measurement range: 0°C～65°C Temperature measurement error: ±0.5°C ~ ±1°C Resolution: 0.01°C BH1750 Light Pre-mounted on the board: Illumination range:0-65535 lx Sensor built-in 16bitAD converter Direct digital output, omitting complex calculations, omission of calibration Does not distinguish between ambient light sources Spectral characteristics close to visual sensitivity High-precision measurement of 1 lux for a wide range of brightness AM2322 NOT Pre-mounted on the board, optionally mounted by yourself: AM2322 -> Tempearture: Range: 40 ~ 80 degree C Error: - 0.5 C Resolution: - 0.1 C AM2322 -> Huminidty: Range: 0~99.99 %RH Error: - 3 %RH Resolution: 0.1 % RH Board Features: On board 5V to 3.3V regulator, can supply power 5V or 3.3V. LDO supply up to 500mA/16V. On board logic shifter, logic level complaint 5V or 3.3V signal. IIC interface, cascadable design, can connect as many IIC devices as you want. All module fully tested before send. Interface: 3.3V GND, SCL, SDA (3.3V logic) CS CS|5 ADR: chip select pin, address pin of BMP280 5V GND, SCL SDA (5V logic) another group – 3.3V GND, SCL, SDA (3.3V logic) Documentation please see on this page.
