Overview

The Pico-Environment-Sensor gives Raspberry Pi Pico the ability to collect environmental data like temperature & humidity, air pressure, ambient light intensity, VOC, UV rays, 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.
