Connection

Replace the original temperature and humidity sensor connected via the 2.5 mm AUX interface with the CO2, temperature, humidity & light sensor.

Installation

Suggest to hang the sensor 4”(10cm) above the canopy of plants to monitor the canopy CO2, temperature and humidity more accurately.

Calibration

To maintain CO2 sensor accuracy, we recommend placing the sensor outdoors in a well-ventilated area with ambient CO2 levels of approximately 400 ppm once per month. Allow the sensor to stabilize for 3 minutes, then perform CO2 calibration using the E42A+ controller.
