Fermion: Multifunctional Environmental Sensor - module with environmental sensors

Description

Multi-functional environmental sensor consisting of SHTC3 temperature and humidity sensor, BMP280 pressure sensor, VEML7700 ambient light sensor and ML8511 UV sensor. The module has a built-in microcontroller that converts raw data from chips to values ​​in commonly used units (℃ and ° F for temperature,% for humidity, kPa for atmospheric pressure, lx for illuminance and mw / m² for UV light). The user has two communication interfaces (UART and I2C) and complete Arduino and Python libraries at his disposal.

The BMP280 is a pressure and temperature sensor. It allows you to read the atmospheric pressure in the range from 300 to 1100 hPa with an accuracy of ± 1 hPa and the temperature in the range from -40 to 85 ℃ with an accuracy of ± 1 ° C. It is an ideal solution for home temperature measurements as well as for measuring altitude when flying at high altitudes.

The SHTC3 from Sensirion is a digital temperature and humidity sensor. It is characterized by high reliability and stability with low energy consumption, fast response and resistance to interference. It offers a high accuracy of ± 2% RH and ± 0.2 ° C.

ML8511 is a UV light sensor. Enables the measurement of the intensity of UV radiation. It is equipped with an internal amplifier. The module can measure the intensity for both the UV-A (320 - 400nm) and the UV-B (280 - 320nm) waves. It generates an analog voltage at its output that is linearly related to the measured intensity of UV radiation.

The VEML7700 is a light intensity sensor. It has a large measuring range (0-120Klx) and an accuracy of 0.0036 lx / ct.
The high accuracy and small size of the module make it suitable for indoor and outdoor environmental monitoring systems. Full documentation with examples of use is available on the product page.
