STEMMA QT SCD-30 NDIR - module with CO2, temperature and humidity sensor

A sensor that detects the concentration of phosphine. Equipped with a factory calibrated probe. It communicates via the I2C interface, UART or analog output. DFRobot SEN0476

The module with the natural gas and LPG concentration sensor (modMQ-5) allows the measurement of the concentration of natural gas, carbon monoxide, alcohol and methane. The module has an analogue output and an output triggered by exceeding the threshold of sensitivity.

Digital gas sensor solution that senses a wide range of Total Volatile Organic Compounds (TVOCs), including equivalent carbon dioxide (eCO2) and metal oxide (MOX) levels, intended for indoor air quality monitoring in personal devices such as watches and phones, but we’ve put it on a breakout board so you can use it as a regular I2C device.
