This multifunctional environmental sensor integrates the SHTC3 temperature & humidity sensor, BMP280 barometric pressure sensor, VEML7700 ambient light sensor, and LTR390 UV sensor (V1.0: ML8511, V2.0: LTR390-UV-01) into one, offering five environmental parameters. Professional sensor chips are chosen for precise measurements, with careful consideration given to the circuit design for optimal heat conduction and layout, ensuring data accuracy.

An onboard MCU processing chip converts raw sensor data into standard unit values, including ℃ and °F for temperature, % for humidity, Kpa for barometric pressure, lx for light illuminance, and mw/cm² for UV light.

This environmental sensor supports UART and I2C communication methods, available in two versions: Gravity and Fermion (breakout). Complete Arduino and Python libraries are provided for easy integration.

Exquisitely designed and compact, it simplifies the wiring and coding in your projects, making it suitable for indoor and outdoor environmental monitoring systems. The V2.0 update replaces the UV sensor model from ML8511 to LTR390-UV-01, enhancing the sensor's capabilities.
