1. Introduction
The AC Infinity CO2 + Light Sensor (Model AC-COS3) is designed to monitor carbon dioxide (CO2) levels and light intensity within controlled environments. This sensor integrates exclusively with AC Infinity AI+ Controllers to provide precise data for automated environmental management, optimizing conditions for plant growth through adaptive programming.

2. Safety Information
- Ensure the sensor is installed in a dry environment, away from direct water exposure or high humidity, to prevent damage.
- Do not attempt to open or modify the sensor. This may void the warranty and cause malfunction.
- Keep the sensor away from extreme temperatures or direct heat sources.
- Use only with compatible AC Infinity AI+ Controllers as specified.
- Handle the sensor and its cable with care to avoid physical damage.

4. Setup
4.1. Compatibility
The AC-COS3 sensor is designed to work exclusively with AC Infinity AI+ Controllers. It is not compatible with older AC Infinity controller models.
4.2. Physical Installation
Mount the sensor in a central location within your grow space, ensuring it is not obstructed by plants or equipment that could interfere with CO2 or light detection. Avoid placing it directly in the path of air currents from fans or CO2 dispersal systems, which could lead to inaccurate readings. The sensor can be mounted on a wall or other flat surface using appropriate fasteners (not included).

4.3. Connection
Connect the integrated UIS cord from the AC-COS3 sensor to an available UIS port on your AC Infinity AI+ Controller. Ensure the connection is secure. The controller will automatically detect the sensor upon connection.
5. Operating Instructions
5.1. Initial Pairing and App Integration
Once connected to your AI+ Controller, the sensor will begin transmitting data. For advanced control and monitoring, pair your AI+ Controller with the AC Infinity Wi-Fi enabled app. The app provides real-time data, historical tracking, and access to advanced programming features for the CO2 and light sensor.

5.2. CO2 Monitoring and Control
The sensor precisely detects CO2 levels. Through the AI+ Controller and app, you can set target CO2 levels. The system will then dynamically activate connected CO2 dispersal equipment (e.g., CO2 generators or tanks connected via UIS plugs) to maintain desired concentrations. This programming also optimizes Fresh Air Exchange (FAE) by coordinating fan operation based on CO2 levels.

5.3. Light Cycle Management
The integrated light sensor allows the AI+ Controller to detect ambient light conditions. This enables automated light cycles, ensuring CO2 dispersal and fan operations are synchronized with the plant's day and night phases for optimal photosynthesis.
5.4. Advanced Programming Features
Utilize the AC Infinity app to access advanced programming options:
- Day & Night Scheduling: Configure distinct CO2 and fan settings for light and dark periods.
- Precision Cycling: Implement specific on/off cycles for CO2 dispersal and fan activity.
- Environmental Data Tracking: Monitor and log historical CO2 and light data for analysis and optimization.
- Minimum Intake Speed: Set minimum fan speeds to maintain air circulation while optimizing CO2 levels.

6. Maintenance
- Cleaning: Periodically wipe the sensor's exterior with a soft, dry cloth to remove dust or debris. Do not use harsh chemicals or abrasive materials.
- Sensor Vents: Ensure the CO2 sensor vents are clear of obstructions to allow for accurate air sampling.
- Cable Inspection: Regularly check the UIS cable for any signs of wear or damage.
7. Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Sensor not detected by controller. | Loose connection, incompatible controller, faulty sensor/port. | Ensure UIS cable is fully inserted. Verify controller is an AI+ model. Try a different UIS port. Contact support if issue persists. |
| Inaccurate CO2 readings. | Sensor obstructed, placed near CO2 source/vent, dirty vents. | Relocate sensor to a central, unobstructed area. Clean sensor vents. Allow time for sensor to stabilize. |
| Light sensor not responding. | Sensor obstructed, direct light not reaching sensor. | Ensure the light sensor component is exposed to ambient light. Check for physical obstructions. |
| App connectivity issues. | Wi-Fi interference, controller not connected to Wi-Fi, app error. | Verify your AI+ Controller is connected to Wi-Fi. Restart the AC Infinity app. Check your network connection. |
