About this item
- Take the guesswork out of indoor gardening with the upgraded 4-in-1 Temp/Humidity/CO₂/Light Sensor. This all-in-one device tracks four key factors that affect plant growth: temperature, humidity, CO₂ levels, and light (ON/OFF), giving you real-time insights so your plants get exactly what they need. The built-in CO₂ sensor measures from 0 up to 655 ppm, working with fans or CO₂ systems to maintain optimal levels. This helps your plants photosynthesize efficiently and grow stronger, without wasting energy or CO₂.
- Build the Right Grow Environment: This 4-in-1 sensor tracks temperature, humidity, CO₂, VPD, and light in real time so you can understand what your plants are experiencing and adjust before growth is affected
- Turn CO₂ Data into Faster Growth: This climate sensor automatically works with fans or CO₂ systems to help keep levels in the optimal range and maintain the proper air balance, helping plants photosynthesize efficiently and grow stronger without wasting energy
- Make Confident Grow Decisions: A high-accuracy Swiss temp/humidity chip and NDIR CO₂ sensor deliver reliable data you can trust for daily adjustments and long-term grow planning; The white housing reduces heat absorption for more consistent readings
- Automate Your Grow: Seamlessly connects to GrowHub E42A+ so you can monitor conditions, set triggers, and manage your grow space remotely instead of constantly checking on it, helping your indoor plants thrive effortlessly
- Versatile for Any Indoor Setup: Ideal for grow tents, greenhouses, bedrooms, or cellars; Whether you're growing herbs, vegetables, or flowers, this sensor helps create a stable microclimate for healthier plants and more consistent harvests
