High-Precision CO2 Sensor Genuine Product [Sensirion SCD41]

Product Description

This is the latest CO2 sensor from a major sensor manufacturer.
It offers improved performance over the SCD40.
Operation has been confirmed.
Compatible with boards and microcontrollers such as Arduino, Raspberry Pi, ESP32, and m5stack.
This single sensor can simultaneously measure three values: CO2 concentration, temperature, and humidity.
With comprehensive official libraries, this is a recommended sensor for easily measuring CO2, even for electronics hobby beginners!
The pin header is already attached, so you can use it right out of the box!

Product Details

This sensor uses the high-precision PAS method to directly measure CO2, unlike the pseudo-measurement methods used by some other manufacturers.
Unlike cheaper sensors, it employs the physical photoacoustic method, ensuring excellent accuracy and reliability.
It connects via I2C, making it compatible with a wide range of boards.
This is a compact and easy-to-handle module.
A recent version update has drastically reduced power consumption, making it suitable for battery-powered applications. (SCD30: 19mA → SCD41: 0.5mA)

Background

I had planned to build a CO2 meter myself, but I no longer have the time to do so, so I am selling it.
It was opened for operation confirmation and pin header attachment. It has been used for approximately 10 minutes.
Major domestic retailers sell this item for ¥4,000 to ¥6,000, and it does not come with a pin header.

Shipping Information

As this is a precision instrument, it will be shipped in an anti-static bag and carefully packaged with bubble wrap or similar materials.
This listing is for the sensor unit only.
