Enviro Indoor - module with environmental sensors and Raspberry Pi Pico W

Description

Module with environmental sensors and Raspberry Pi Pico W board. It is equipped with a gas, pressure, temperature and humidity sensor BME688 and a color and light intensity sensor BH1745. The set is controlled by the RP2040 microcontroller board equipped with two ARM Cortex-M0 + cores operating at 133 MHz, 264 KB RAM and 2 MB of external QSPI flash memory. In addition, the board is equipped with the Infineon CYW43439 system, extending the board with wireless connectivity.

The BME688 is a chip specially developed for mobile applications where low energy consumption is a key requirement. The gas sensor on the BME688 can detect a wide range of air quality gases, including volatile organic compounds (VOCs) from paints (such as formaldehyde), varnishes, paint strippers, cleaning products, furniture, office equipment, adhesives and alcohol. In addition, it allows you to measure pressure, temperature and air humidity. The BH1745 chip is a color and light intensity sensor. It offers a wide detection range, suppression of light noise 50/60 Hz. These types of sensors are widely used to detect the ambient light temperature and adjust the brightness of, for example, the display. Additional sensors can be connected by the user thanks to the Qwiic/Stemma QT connector available on the board.

The device is designed to work well on battery power. The Enviro board has a built-in RTC (real time clock) so you can periodically wake the microcontroller from sleep mode, read (and optionally connect to Wi-Fi), and then sleep again, giving you months of unlimited battery life. The set is dedicated to projects of indoor air control stations. Examples of use along with the instruction manual are available on the project website.
