Overview

The Pico-Environment-Sensor gives Raspberry Pi Pico the ability to collect environment data like temperature & humidity, air pressure, ambient light intensity, VOC, UV ray, etc. It can also be used to build a robot that can detect motion and orientation.

Features

  • Standard Raspberry Pi Pico header, supports Raspberry Pi Pico series.
  • Onboard TSL25911FN digital ambient light sensor, for measuring IR and visible light.
  • Onboard BME280 sensor, for measuring temperature, humidity, and air pressure.
  • Onboard ICM20948 motion sensor, accelerometer, gyroscope, and magnetometer.
  • Onboard LTR390-UV-1 sensor, for measuring UV rays.
  • Onboard SGP40 sensor, for detecting ambient VOC.
  • I2C bus, allows retrieving data by just using two wires.

Setup environment

Please refer to Raspberry Pi's guide: https://www.raspberrypi.org/documentation/pico/getting-started/

python

1. Refer to Raspberry Pi's guides to setup Micropython firmware for Pico.
2. Download the codes with commands. 

sudo apt-get install p7zip-full
cd ~
sudo wget  https://www.waveshare.com/w/upload/f/f9/Pico-Environment-Sensor-code.7z
7z x Pico-Environment-Sensor-code.7z -o./Pico-Environment-Sensor-code
cd ~/Pico-Environment-Sensor-code

3. Open the Thonny IDE, and select the board (MicroPython(Raspberry Pi Pico)) and the port (ttyACM0).
