1Onboard TSL25911FN digital ambient light sensor can measure infrared light and human visible light. 2The onboard BME280 temperature, humidity and air pressure sensor can measure temperature, humidity and air pressure. 3With onboard ICM20948 motion attitude sensor, this can measure acceleration, gyroscope, magnetometer. 4Onboard Si1145 red ultraviolet sensor can measure infrared and ultraviolet. And onboard SGP40 gas sensor can detect environmental VOC. 51.3in OLED onboard can realtime display of environmental measurement data. 6With I2C interface communication, just two wires can be read and displayed. 7For nano motherboard can collect the temperature and humidity, atmospheric pressure, ambient light, VOC, infrared, ultraviolet and other sensor data of the surrounding environment, which can also easily DIY a robot that can detect movement posture and orientation. Item Type: Environmental Sensor Expansion Board Material: PCB Purpose: ForJetson Nano motherboard, it can collect the temperature and humidity, atmospheric pressure, ambient light, VOC, infrared, ultraviolet and other sensor data of the surrounding environment. It can also easily DIY a robot that can detect movement posture and orientation.
