Environment Sensor Module
Features At A Glance
The environmental sensor expansion board specially designed for Raspberry Pi is equipped with rich resources such as ambient light, VOC, infrared, ultraviolet, gyroscope, accelerometer, magnetometer, barometer, temperature and humidity sensor, etc., and uses I2C interface for communication.
As long as you use your hands, you can easily DIY the Raspberry Pi into a robot that can detect the movement posture and orientation, or you want the Raspberry Pi to collect the temperature and humidity, atmospheric pressure, ambient light, VOC, infrared, and ultraviolet of the surrounding environment. Wait for the sensor data, then take him!
- Based on Raspberry Pi 40PIN GPIO interface design, suitable for Raspberry Pi series motherboards
- Onboard TSL25911FN digital ambient light sensor, which can measure infrared light intensity and visible light of the human eye
- The onboard BME280 temperature, humidity and air pressure sensor can measure temperature, humidity, and air pressure
- Onboard ICM20948 motion attitude sensor, which can measure acceleration, gyroscope, magnetometer
- On-board LTR390-UV-1 ultraviolet sensor, which can measure the intensity of ultraviolet light
- Onboard SGP40 gas sensor, can detect environmental VOC
- I2C interface communication, two wires can be read
- Provide complete supporting information manual (Raspberry/Arduino/STM32 sample program)
