Product Description
SCD40 High - Performance 2 - in - 1 Gas Sensor Module for Indoor Air Quality Monitoring
The SCD40 Gas Sensor Module is a next - generation device designed for precise indoor air quality monitoring. It combines CO?, temperature, and humidity sensing capabilities in a single, compact unit.
Key Features:
CO? Sensing: Measures CO? concentrations from 400 - 2000 ppm with high accuracy of ±(40 ppm + 5%). This allows for intelligent regulation of indoor ventilation systems to maintain a healthy environment.
Integrated Sensors: Equipped with an on - chip temperature and humidity sensor. The built - in temperature and humidity compensation ensures accurate readings of relative humidity in the range of 0 - 95%RH with a typical accuracy of 6%RH.
Low Power Design: Operates at an average power consumption of less than 0.4 mA at 5 V with a measurement cycle of 1 measurement every 5 minutes. This makes it ideal for battery - powered applications and long - term continuous monitoring.
Digital I2C Interface: Features a digital I2C interface with a 2.54mm pitch pin interface for easy connection to microcontrollers, development boards, and other devices. The interface pins include GND (negative power input), VDD (positive power input), SCL (I2C clock port), and SDA (I2C data port).
Compact Size: Housed on a PCB 13.4 × 21.6mm, making it suitable for space - constrained applications.
