This multifunctional environmental sensor comprises SHTC3 temperature & humidity sensor, BMP280 barometric pressure sensor, VEML7700 ambient light sensor, and ML8511 UV sensor 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 the 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 with the 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/m² for UV light. The environmental sensor supports two communication methods(UART and I2C) and provides two versions: Gravity and Fermion(breakout), also Complete Arduino and Python libraries are 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. Applications:
  1. Home indoor and outdoor environment detection system.
  2. Environmental monitoring work.

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
