SIMPLE STRUCTURE: The gas detection module has a simple structure and can be used in various environments. Specification: Item Type: Ozone Gas Detection Module Material: PCB Power Consumption (Current): 150mA DO Output: TTL Digital Quantities 0 and 1 (0.1V and 5V) AO Output: Analog Level Signal Detection Range: 10ppm to 1000ppm Working Temperature: -10℃ to 50℃ (Nominal Temperature 20℃) 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 be preheated for about 20s to stabilize the measured data. The sensor heating is normal because there is an electric heating wire inside, but if it is hot, it is considered abnormal.2. Long term exposure to harsh environments. Regardless of whether the sensor is powered on or not, prolonged exposure to adverse environments such as high humidity, high temperature and high pollution will seriously affect the performance of the sensor.
