MQ131 Ozone Gas Sensor Module��is a compact and highly sensitive sensor designed for detecting ozone levels in the ambient air. It utilizes��tin dioxide (SnO2)��as the sensing material, which has low conductivity in clean air but becomes more conductive in the presence of ozone. The module can detect ozone concentrations ranging from��10-1000 ppb��for low concentrations and��10ppm-1000ppm��for high concentrations. It features both��analog output��and��TTL level digital output, making it compatible with microcontroller-based systems for direct integration.

Key Features:

1. Wide Detection Range: Capable of detecting ozone concentrations from��10PPB to 1000PPB��10ppm to 1000ppm��(high concentration).

2. Dual Signal Output:

   • Analog Output: Provides a voltage signal that varies with ozone concentration.

   • TTL Level Digital Output: Can be directly connected to a microcontroller's I/O port.

3. Quick Response and Recovery: The sensor quickly responds to changes in ozone levels and recovers to baseline values efficiently.

4. Trimmer Potentiometer: Allows setting of threshold levels for the digital output.

5. Long Life and Low Cost: Built for durability with a long operational lifespan and cost-effective design.

6. LED Indicators: Equipped with LEDs that indicate signal outputs and sensor status.
