SCD40/SCD41 CO2 Carbon Dioxide Sensor I2C Communication Gas Temperature Humidity Sensor Temperature Humidity Sensor Module 2 in 1 for DIY Kits
Feature:
1. Benchmark Accuracy and Range: Temperature humidity sensor from Sensirion are next-generation miniature CO2 sensors that provide high precision within a specified range (SCD40: 400-2000 ppm, SCD41: 400-5000 ppm) making them ideal for indoor air quality monitoring.
2. Power Efficiency and Effective Communication: Operating within a power supply voltage range of 2.4-5.5 V, temperature humidity sensor deliver high accuracy (± (40 ppm + 5%)) and communicate via a digital I2C interface. They have a low power consumption, averaging <0.4 mA @ 5 V for one measurement every 5 minutes.
3. Integrated Temperature and Humidity Sensor: Flammable gas sensor feature an on-board temperature and humidity sensor which provides compensation and ensures more accurate measurements.
4. Easy Integration: With their compact size (22*14*8MM) and standard I2C interface, gas sensor modules can be easily integrated with controllers or microprocessors. The pin interface includes GND for power supply negative input, VDD for power supply positive input, SCL for I2C clock port, and SDA for I2C data port.
5. Broad Application Potential: By providing precise CO2 concentration measurements, gas temperature humidity sensor can intelligently regulate indoor ventilation systems, contributing to a healthier and more efficient environment over time. This makes them ideal for applications ranging from indoor air quality monitoring to greenhouse control and industrial process monitoring.
