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
