VIVOSUN 4-in-1 Temperature, Humidity, CO₂ and Light Sensor
Monitor temperature, humidity, carbon dioxide and light ON/OFF status in your indoor growing space. The VSE-CO2S4 connects to the GrowHub E42A+ for environmental monitoring and compatible automation, with VPD information to help guide daily adjustments.
About This Item
- Four environmental inputs: Track temperature, relative humidity, CO₂ and whether the light is on or off. Light detection is not a lux or PPFD measurement.
- CO₂ monitoring: An NDIR CO₂ sensor measures concentrations from 0 to 40,000 ppm.
- Temperature and humidity sensing: A Swiss temperature/humidity chip provides environmental data, while the white housing helps reduce heat absorption.
- GrowHub E42A+ integration: Connect to the compatible controller to monitor conditions and configure supported triggers in the VIVOSUN App. Not compatible with the E42 controller.
- Flexible placement: The approximately 3 m cable and compact housing suit grow tents, greenhouses and other indoor monitoring spaces.

Application Guide
- Confirm your controller is the GrowHub E42A+ before connecting the sensor; it does not work with E42.
- Position the sensor where it can sample representative growing conditions and detect the relevant light state. Follow the manufacturer’s installation guidance.
- Use the controller and app to review readings and configure supported equipment automation. Controller, fans and CO₂ equipment are not represented as included.
