CO2L Unit with Temperature and Humidity Sensor (SCD41) photo

Unit CO2L is a digital air CO₂ concentration detection unit with a low power consumption mode for single measurements. It is equipped with Sensirion's SCD41 sensor and a power step-down circuit, utilizing I2C communication. This unit is suitable for measuring air environmental conditions, with a typical accuracy for CO₂ measurement of ± (40 ppm + 5% of reading), and a range of 400 ppm ~ 5000 ppm. It also measures ambient temperature and humidity. Features CO2 concentration detection… (M5Stack U104)
