Growlink ESM3 Climate sensor with CO2

Perfect climate control for professional results

The Growlink ESM3 Climate Sensor with CO2 is a high-end device that provides you with the most accurate environmental data in your growing space. By monitoring key parameters in detail, you can optimise the conditions for your plants and achieve professional results, whether you are growing herbs, chillies or other annuals.

Key features of the ESM3 with CO2 sensor

• Comprehensive measurement: monitors temperature, relative humidity (RH), vapour pressure (VPD), light level and CO2 concentration.
• High accuracy: Equipped with temperature and pressure compensation for accurate data at any altitude.
• Long-term stability: Designed for reliable, continuous operation with low power consumption.
• Durable design: High resistance to contamination ensures reliability even in harsh conditions.
• Easy integration.

Optimise every detail of your growing space with the easy-to-use, easy-to-follow automation system that is automatically integrated into the GrowLink system.

This sensor is the brain of your environmental management. It continuously collects data on all the key factors that affect the growth and health of your plants. Thanks to integrated pressure and temperature compensation sensors, CO2 measurements are extremely accurate, regardless of external conditions. Its low power consumption and resistance to dust and moisture make it a reliable partner for long-term cultivation.

For the most accurate results, place the sensor directly in the microclimate zone you want to monitor. The ideal position is at or just above the level of the plant tops. This will ensure that the data accurately reflects the conditions your plants are in.

Compatibility and easy installation

Before purchasing a sensor, make sure your controller is compatible. The ESM3 sensor works exclusively with Precision Irrigation Controllers (PICs) that have Bluetooth capability (designated as ESP PICs) and with Connect Controller units. Older PIC versions are not supported.

You can easily check compatibility by looking at the front door of your PIC unit - it must have a Bluetooth sticker on it. You can connect up to four of these climate sensors to a single PIC controller to get a perfect overview of the different zones.

Installation is very simple. First, check and update your controller firmware to the latest version via the Growlink app. Then plug the sensor into a free SDI-12 port. Within a few minutes, the sensor is automatically detected and its data starts to be displayed in the app.
