Fermion - Multifunctional Environmental Sensor - DFRobot SEN0500

The environmental sensor module consists of SHTC3 temperature and humidity sensor, BMP280 pressure sensor, VEML8511 ambient light sensor and ML8511 UV radiation sensor. The environmental sensor uses two communication interfaces UART and I2C. It is powered by 3.3 V. The sensor can be used to create indoor and outdoor environmental monitoring systems.

Fermion - multifunctional environmental sensor - DFRobot SEN0500.

The multifunctional environmental sensor comes with two 6-pin single row goldpin strips.

• The module has leads in the form of solder fields to which the included goldpin connectors should be soldered
• Choice of two communication interfaces I2C and UART
• Highly integrated module, can monitor different data at the same time (temperature, humidity, barometric pressure, altitude, ultraviolet intensity, ambient light intensity)
• The module guarantees the accuracy of the data thanks to the sensors selected.

• Indoor air quality monitoring
• Element of a weather station
• Used in smart home projects

The sensor should be connected with the microcontroller according to the diagram. The UART connection is on the left side and the I2C connection is on the right side of the illustration.

• 3V3 - power supply
• GND - ground
• RXD - receiving UART
• TXD - transmitting UART
• SCL - I2C clock line
• SDA - I2C data line
• RST - Reset pin

Multifunctional environmental sensor - connection (UART on the left, I2C on the right) with FireBeetle ESP32-E.
