{"title":"Gravity: I2C Oxygen Sensor","handle":"gravity-i2c-oxygen-sensor","url":"/products/gravity-i2c-oxygen-sensor","description":"The Gravity: I2C Oxygen Sensor is based on electrochemical principles and it can measure the ambient O2 concentration accurately and conveniently. With high anti-interference ability, high stablility and high sensitivity, this arduino-compatible oxygen sensor can be widely applied to fields like portable device, air quality monitoring device, and industries, mines, warehouses and other spaces where air is not easy to circulate.This compact dfrobot oxygen sensor supports I2C output, it can be calibrated in the air, can accurately measure the oxygen concentration in the environmentit. It is compatible with many mainboards like Arduino Uno, esp32, Raspberry Pi and so on. Its effective range is 0~25%Vol, and resolution can reach to 0.15%Vol. It supports wide range input voltage: 3.3V to 5.5V. Moreover, the lifetime is as long as 2 years. With simple Gravity interface and practical sample code, you can build your own oxygen concentration monitor easily and conveniently.FEATURES\nHigh sensitivity\nI2C Interface\nCompatible with both 3.3V and 5V micro-controllers\nPolarity protection\nSPECIFICATION\nDetection of Gas: oxygen\nOperating Voltage: 3.3 to 5.5V DC\nOutput Signal: I2C output\nMeasurement Range: 0~25%Vol\nMaximum Measurement limit: 30%Vol\nResolution: 0.15%Vol\nSensitivity: (0.10±0.05) mA (in the air)\nStability: <2% (Every month)\nRepeatability: <2%\nResponse Time: ≤15 seconds\nOperating Temperature: -20～50℃\nOperating humidity: 0～99%RH (no condensation)\nPressure Range: standard atmospheric pressure ±10%\nLifetime:> 2 years (in the air)\nDimension(L x W x H): 37 * 27 * 24.5 mm/1.46 * 1.06 * 0.97 inches\nWeight:0.037kg\nDOCUMENTSProduct wikiMore Documents","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3970,"title":"Default Title","sku":"DF-SEN0322","price":91.27,"on_sale":false,"in_stock":true,"available_quantity":396,"option1":"Default Title"}]}
