The Multifunctional Environmental Sensor Breakout is a compact and versatile device that combines several sensors into one, providing five different environmental parameters - temperature, humidity, barometric pressure, ambient light, and UV light. It is equipped with professional sensor chips for each type of measurement, and the circuit design has been carefully optimized to ensure the accuracy of the data.
The sensor has an onboard MCU processing chip that converts the raw sensor data into standard units, such as degrees Celsius or Fahrenheit for temperature, percent for humidity, Kpa for barometric pressure, lx for light illuminance, and mw/m² for UV light. It supports two communication methods - UART and I2C - and is available in two versions - Gravity and Fermion (breakout). Complete Arduino and Python libraries are also provided to make it easy to use this sensor in your projects.
