Who is it suitable for and how to use it?
CO2 gas sensor module ideal for engineers, electronics enthusiasts and IoT project developers. Use the module in home automation systems, ventilation control according to air quality, laboratory experiments and environmental monitoring stations. Practical advice: set sensor in the room where people live provides real-time information on air quality and helps in decision-making on ventilation. Professionals use CO2 gas sensor module for energy efficient building management systems.
Buyer questions
Q: What CO2 level is safe to live?
The normal CO2 level in the living room should be below 1000 ppm. Exactly over 1000 ppm shows poor ventilation. TENSTAR the sensor accurately shows these values to you to help you make decisions about ventilation and air quality.
Q: Is this module combined with Raspberry Pi?
Yes, TENSTAR SCD40 / SCD41 uses standard I2C protocol and works well with Raspberry Pi, Arduin and other microcontrollers. Connection is simple: connect SDA and SCL wires to the corresponding I2C wires on your computer.
Q: What is product warranty and delivery time?
In our store TENSTAR modules are sent with standard 12 month warranty. Delivery time in Lithuania - 2-5 working days. If the module is not operational, we return the full amount within 30 days.
TENSTAR SCD40 SCD41 CO2 gas sensor module is a reliable and practical solution for those who seek to monitor air quality. Whether you are planning home automation, laboratory equipment or commercial systems, this sensor provides the required accuracy and reliability.

This sensor will always work the cost. Payments are fast, very active and stable, no noise at all. It can easily detect your presence in a room within a minute by raised co2 days. When window is opened, values drop immediately.
Customer –
Fast shipping, works as intended.

Original sense scd41
Alright –
Seems to be quite accurate, shows 430-440ppm outside, ~650 in room with 1 adult and slightly open window, up to 1100 in closed room with 2 adults. Works fine with esp32
Customer –
Product as described. Highly recommended.

I was a bit skeptical at first, but after setting the sensor to PI Zero, I am complete agreed: very precise and relative. I can only remember it!
C***e –
The price is a bit high, but the product works very well for small projects with esp32. it accurately results co2, temperature, and humidity. great for big electronics!
M***k –
Fast delay.
Scd connected to esp32 is monitoring co2 level in my daughter room. Accurate readings – topped to 3500 ppm when she refused to open door and window for whole night :/
