Environment Sensor Module for Raspberry Pi Pico

Now your Raspberry Pi Pico can monitor your environment with this fantastic Environmental Sensor Module from Waveshare!

This Pico HAT can monitor the following aspects of your local environment using its range of onboard sensors:

• Visible light
• IR light
• UV rays
• Temperature
• Humidity
• Air Pressure
• Air Quality/VOC (Volatile Organic Compounds)
• Motion and position
  • 3-axis Accelerometer
  • 3-axis Gyroscope
  • 3-axis Magnetometer

The HAT comes pre-assembled with female headers allowing you to slot your Pico in place, ready to use the online resources and example code to get you up and running quickly and easily. The stacking headers allow you to connect other components to your project with ease.

Raspberry Pi Pico not included. You’ll need a Pico with male headers soldered to it. You can grab a Pico here and Pico male headers here, or buy a Pico with pre-soldered headers.
