Introduction
The Spider Farmer GGS Sensor Pro Kits provide comprehensive environmental monitoring for indoor growing. This system integrates a 4-in-1 sensor for VPD, PPFD, Temperature, and Humidity, along with a dedicated CO2 sensor. Designed for precision and ease of use, these sensors help optimize your growing environment for enhanced plant growth and yield. This manual provides detailed instructions for setup, operation, maintenance, and troubleshooting.
Safety Information
- Read all instructions carefully before operating the device.

Product Overview
The Spider Farmer GGS Sensor Pro Kits consist of two primary sensors: the 4-in-1 Sensor Pro and the GGS CO2 Sensor. These devices work in conjunction to provide comprehensive data on your growing environment.
4-in-1 Sensor Pro
This sensor integrates four critical measurements: Temperature, Humidity, PPFD (Photosynthetic Photon Flux Density), and VPD (Vapor Pressure Deficit). It provides real-time data to help you maintain optimal microclimate conditions for plant growth.

GGS CO2 Sensor
The CO2 sensor is capable of detecting carbon dioxide concentrations from 0 to 5000 PPM, providing swift and precise data crucial for CO2 supplementation strategies in controlled environments.

Setup and Installation
Follow these steps to properly install and connect your Spider Farmer GGS Sensor Pro Kits:
- Sensor Connection: Connect the GGS 4-in-1 Sensor Pro and the CO2 Sensor to your Spider Farmer controller (e.g., AC5 or AC10) using the provided RJ12 cables. Ensure a secure connection.
- Important Note on Existing Sensors: When using the SensorPro, it is crucial to disconnect any original temperature and humidity sensors from your controller or power socket. This ensures that only one sensor is providing readings, preventing interference and inaccurate data.
- PPFD Bracket Installation: Attach the PPFD Bracket to the 4-in-1 Sensor Pro using the provided screw. This bracket allows for optimal positioning of the PPFD sensor for accurate light intensity readings.
- Mounting: Position the sensors in your growing environment where they can accurately measure the desired parameters. The PPFD sensor should be placed at canopy level for precise light readings.

Data Notes and Troubleshooting during Setup:
- If PPFD shows "---": This indicates no device is connected. Check your RJ12 cable connections to the controller.
- If PPFD shows "0": Open the cap on the 4-in-1 Sensor Pro to expose the white detection ring.
- Abnormal VPD readings: If the moisture window is wet, dry it or allow it to air dry for 30 minutes.
Operating Instructions
The GGS Sensor Pro Kits are designed to work seamlessly with Spider Farmer controllers (AC5, AC10) and the Spider Farmer APP, providing comprehensive control and monitoring of your grow environment.
Compatibility and Control Options
The GGS Sensor Pro is compatible with the GGS Controller, AC5, or AC10 power strip kits. This allows you to monitor and adjust multiple devices through a single interface, streamlining your plant management.

Monitoring Environmental Parameters
The sensors provide real-time data for:
- Temperature: Accurate readings within -4°F to 140°F (-20°C to 60°C) with ±1.8°F (±1°C) accuracy.
- Humidity: Measures 0 to 100% RH with ±3% RH accuracy.
- PPFD: Detection range of 0~4000 µmol/m²/s with ±5% accuracy, covering the 400nm-700nm response spectrum.
- VPD: Calculated from temperature and humidity, crucial for plant transpiration.
- CO2: Detects concentrations from 0 to 5000 PPM with ±50 PPM accuracy.
Data refreshes up to every 1 second, ensuring you always have the latest information.
PPFD Mode Intelligent Control
Utilize the Spider Farmer APP to enable PPFD mode and set target values for smart dimming based on your plant's growth stage. This allows for precise growth management and intelligent adjustment of light intensity to simulate natural light environments.

Maintenance
Proper maintenance ensures the longevity and accuracy of your sensors:
- Cleaning: Gently wipe the sensor surfaces with a soft, dry cloth. Do not use abrasive cleaners or solvents. For the PPFD sensor, ensure the detection ring is clean and unobstructed.
- Moisture Window: If the VPD moisture window appears wet, gently dry it or allow it to air dry for at least 30 minutes before taking readings.
- Storage: When not in use, store the sensors in a cool, dry place away from direct sunlight and extreme temperatures.
- Cable Management: Ensure all cables are neatly routed and not under tension to prevent damage.
Troubleshooting
If you encounter issues with your Spider Farmer GGS Sensor Pro Kits, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| PPFD displays "---" | No device connected. | Check all RJ12 cable connections between the sensor and the controller. Ensure they are securely plugged in. |
| PPFD displays "0" | The cap on the 4-in-1 Sensor Pro is closed, obstructing the detection ring. | Open the cap to expose the white detection ring on the 4-in-1 Sensor Pro. |
| Abnormal VPD readings | Moisture on the VPD window. | Dry the moisture window or allow it to air dry for 30 minutes. |
| Inaccurate Temperature/Humidity readings | Conflicting sensors or sensor obstruction. | Ensure all original temperature and humidity sensors are disconnected. Verify the sensor is not obstructed or placed in an area with poor air circulation. |
| CO2 readings are inconsistent or absent | CO2 sensor not properly connected or faulty. | Check the RJ12 connection for the CO2 sensor. Ensure it is clean and secure. If issues persist, contact support. |
