Apollo SCD40 | CO2 Module

CO2 Sensor suitable for Apollo MTR-1 / MSR-2 / AIR-1 / R-PRO-1

Discover the secret to a healthy indoor climate. High CO2 concentrations in your home can unknowingly lead to fatigue, headaches, and reduced concentration. The Apollo SCD40 CO2 module is the ideal solution for accurately monitoring the air quality in your home or office and taking your home automation to the next level. This compact add-on is specially designed for seamless integration with your existing Apollo equipment.

The CO2 Module is very easy to install, click here for the manual.

Key Benefits

• Ultra-accurate measurements : Unlike many other sensors that estimate CO2 levels (eCO2), the SCD40 uses a true NDIR (Non-Dispersive Infrared) sensor. This guarantees reliable and precise measurements of the actual CO2 concentration, so you can always rely on the data.
• Seamless integration : This module is designed as a direct upgrade for the Apollo MTR-1, MSR-2, AIR-1, and R-PRO-1. A simple I2C connection allows you to add a CO2 sensor to your existing multisensor.
• Perfect for Home Assistant and Homey : Apollo products are known for their excellent compatibility with Home Assistant and Homey. This SCD40 module is also easily configured via ESPHome, after which the measurements are immediately available for all your automations.
• Easy installation : Installation is surprisingly simple. Simply align the "X" on the sensor module with the "X" on the Apollo board, and you're good to go. After a quick 5-minute outdoor calibration, the sensor is ready to use.
• Compact and discreet : Thanks to the clever and compact design of the Apollo Multisensors, the sensor can be placed discreetly in any room, without becoming a disturbing element in your interior.

Practical application: automate your ventilation

Connect the SCD40 to your home automation system and create smart home automation. A practical example:

Set an automation that automatically switches your mechanical ventilation to a higher setting when the CO2 level in the living room rises above 1200 ppm. As soon as the level drops again, the ventilation switches back. This way, you always have fresh air without having to think about it, and you save energy when ventilation isn't necessary.
