CO2L

SKU:U104

Description

UNIT CO2L is a digital air CO2 concentration detection unit with a single-measurement low-power mode, built-in Sensirion's SCD41 sensor and power buck circuitry, and I2C communication. The unit is suitable for the measurement of air ambient conditions with a typical accuracy of ± (40 ppm + 5 % reading) for CO2 measurements over a measuring range of 400 ppm – 5000 ppm while measuring ambient temperature and humidity.

Features

• CO2 concentration detection
• Temperature and humidity measurement
• Low power consumption (single measurement supported)
• Integrated 5V -> 3.3V LDO
• HY2.0 4P interface
• 2x LEGO compatible holes

Applications

• CO2 concentration detection
• Temperature and humidity monitoring
