## Overview

The Teyleten Robot SCD41 is a cutting-edge CO2 sensor module featuring a wide 2.4-5.5V supply range, exceptional ±(40 ppm + 5%) accuracy, and integrated temperature and humidity sensors. Its low power consumption (<0.4 mA at 5V) and I2C digital interface make it ideal for intelligent indoor air quality management and energy-efficient IoT applications. Designed for professionals seeking reliable, cost-effective environmental monitoring.

## Description

The SCD41 has high accuracy and cost effectiveness, and the module leads the power supply and communication pins with 2.54mm pitch row pin interface. On-chip temperature and humidity compensation is achieved by built-in temperature and humidity sensors for humidity and temperature measurement. SCD41 enables intelligent adjustment of indoor ventilation system based on CO2 concentration, and indoor air quality helps to maintain a healthy and efficient environment with low CO2 concentration over a period of time.

Review: Great device. - This is a good sensor at half the price of the identical unit from other sources. Be careful when establishing the ground. In my test set up I used a separate power source from the Arduino and failed to use a common ground. This cost me two days of debugging until I figured out my mistake. Keep in mind that this Is a precision product. Grounding and shielding will be important if used in a field environment.
Review: Works well; be mindful of airflow - This sensor worked well with esphome and reported very plausible values out of the box even with self-calibration disabled. I believe it's a knock-off of the original sensor, but it seems to work well enough. If you have issues with noise, note that these sensors are sensitive to airflow and sound due to how they measure CO2. The sensor should be exposed to open air, but not directly forced airflow.

### ⭐⭐⭐⭐⭐ Very accurate
*by M***S on January 18, 2026*

I'm running Tasmota on an ESP32 with a 4000mAh battery and OLED display. Totally easy to use, just plug it in. Uses I2C, Tasmota sees it without any configuring.
