Feature: 1. Fast Detection: This ozone gas detection module has a fast response time and a short response time, enabling fast and stable detection of gas concentrations and ensuring timely and accurate information on the gas content of the environment. 2. Double Panel Design: This ozone gas detection module has an excellent double panel design with power indicator and TTL signal output indicator. 3. Voltage Varies With Concentration: The ozone gas detection module has a DO switching signal (TTL) output and an AO analogue signal output, the analogue output voltage varies with concentration, and TTL output high and low level can be directly connected to microcontroller or relay module. 4. High Accuracy: This ozone gas detection module is highly sensitive and accurate, enabling effective detection of ozone in the air. 5. Automatic Calibration: The ozone gas detection module does not require external calibration and can be calibrated automatically, reducing operational difficulties and providing a better experience during use. 6. Wide Application: This ozone gas detection module has a simple structure and can be used in a variety of environments, with a wide range of applications for household, environmental gas and ozone gas detection. Specification: Item Type: Ozone Gas Detection Module Material: PCB ABS Input Voltage: DC5V (Maximum24V) Power Consumption (Current): 150mA DO Output: TTL digital 0 and 1 (0.1V and 5V) AO Output: Analogue level signal Detection Range: 10 to 1000PPB Operating Temperature: -10 to 50°C (nominal temperature °C) Humidity: 95% RH (nominal humidity 65% RH) . Package List: 1 x Ozone Gas Detection Module Note: 1. After the sensor is powered on, it needs to warm up for about 20S before the measured data is stable. It is normal for the sensor to be hot because there is an electric heating wire inside, if it is hot it is not normal.2. Long term exposure to harsh environments. Whether the sensor is energised or not, if exposed to high humidity, high temperature, high pollution and other unfavourable environments for a long time, the performance of the sensor will be seriously affected.
