SCD41-D-R2 Board

Rebuild of a SCD41 Board because I was happy to create it my self so save some bucks. (https://www.amazon.com/HiLetgo-Temperature-Humidity-Communication-Monitoring/dp/B0CDWXWCS5)

Description

SCD41 is the next generation of micro carbon dioxide sensor of Sensirion. SCD41 has high precision and high performance. The module leads out the power supply and communication pins with a 2.54mm spacing pin interface. On chip temperature and humidity compensation realizes humidity and temperature measurement through built-in temperature and humidity sensor. SCD41 can realize intelligent regulation of indoor ventilation system according to carbon dioxide concentration. Indoor air quality helps to maintain a healthy and efficient environment under low carbon dioxide concentration for a period of time.
