About the Product

This multifunctional environmental sensor comprises 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 and offers 5 kinds of environmental parameters. Professional sensor chips are selected for each kind of parameter measurement. The reasonable layout and heat conduction of main chips are carefully considered in the circuit design, which effectively guarantees the accuracy of the data.

The product has an MCU processing chip onboard that converts the sensor raw data into values in standard units so you can directly use them. For instance, ℃ and °F for temperature, % for humidity, Kpa for barometric pressure, lx for light illuminance, and mw/cm² for UV light.

The environmental sensor supports two communication methods (UART and I2C) and provides two versions: Gravity and fermion (breakout). Complete Arduino and Python libraries are also provided.

Exquisite and small, you can use it to make indoor and outdoor environmental monitoring systems, or for your environmental monitoring topics. This DFRobot environmental sensor can greatly simplify the wiring and codes of your project.
