DFRobot SEN0321 Gravity ozone sensor I2C, electrochemical

Viss par produktu

Electrochemical ozone sensor for accurate measurement of O3 concentration in the environment. Compatible with Arduino and Raspberry Pi, the module can be used in portable measuring stations and disinfection rooms. Measurement range from 0 ppm to 10 ppm. Communicates via I2C interface and has a built-in Gravity connector, making it easier to connect to the main module. The sensor is powered from 3.3 V to 5.5 V. The sensor has a service life of 2 years.

Notes:

• Do not connect or disconnect the module sensors
• It is forbidden to interfere with the module electronics.
• Avoid contact with organic solvents (silicones and other adhesives), pharmaceutical products, oils and high concentrations of gases
• The module must not be completely immersed in resin or in an anaerobic environment.
• The module cannot be used for a long time in an environment with corrosive gases.
• The device must be protected from excessive shock and vibration.
• The module warm-up time after the first start-up is 24–48 hours.
• Do not tear the white membrane from the sensor.
• The module should not be installed in a highly convective environment.
• Do not place the module in high concentration organic gases for a long time.
