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.
Description: V2.0 changes the UV sensor model compared to V1.0, the UV sensor in V1.0 is ML8511, and the UV sensor in V2.0 is LTR390-UV-01.

Project 1. How UART Protocol Works - Gravity: UART Fiber Optic Transceiver Module
Introduction:
In this video, we will talk about the UART protocol. We're using Gravity: UART Fiber Optic Transceiver Module, which runs at 2000000 baud at any time within a distance of up to 10km, to make a weather station.

Project 2. Make a Weather Station Using Environmental Sensor Introduction:However, it only tells temperature in a relatively large range. Sometimes we need environmental parameters in a specific place like a fishpond, greenhouse, an open field, etc. Here I want to know the exact temperatures during a day on my terrace. So I decide to make a weather monitoring station that outputs the real-time data I need.
