Feature:1. Short Response Time: The gas sensor module has a short response time, which enables it to detect gas concentration quickly and stably and grasp the gas content of the environment.2. Double Panel Design: The gas sensor module adopts double panel design with power indicator and TTL signal output indicator.3. DO Switching Signal: O3 gas sensor module with DO switching signal (TTL) output and AO analog signal output, analog output voltage changes with concentration TTL output high and low levels.4. High Sensitivity: Ozone gas sensor module with high sensitivity and accuracy can effectively detect ozone in air without external calibration and can be calibrated automatically.5. Simple Structure: The gas sensor module has a simple structure and can be used in a variety of environments with a wide range of applications to meet the needs of a variety of applications and a good use experience.Specification:Item Type: Gas Sensor ModuleMaterial: PCB, ABSInput Voltage: DC5V (Maximum24V) Power Consumption (Current): 150mADO Output: TTL digital 0 and 1 (0.1V and 5V)AO Output: Analog levels signalOperating Temperature: -10 - 50 (Nominal Temperature )Humidity: 95% RH (Nominal humidity 65% RH).Package List:1 x Gas Sensor ModuleNote:1. After the sensor is powered on, it needs to warm up about 20S, the measured data is stable, the sensor heating is normal, because the internal electric heating wire, if it is hot, it is not normal.2. Long term exposure to harsh environments. Whether the sensor is energized or not, if exposed to high humidity, high temperature, high pollution and other adverse environments for a long time, will seriously affect the performance of the sensor.
