The 7Semi SCD43 CO₂ Temperature & Humidity Sensor Breakout Board I2C Mini is a compact and reliable CO₂ sensor module designed for indoor air-quality monitoring and environmental sensing applications. Powered by Sensirion’s PASens® photoacoustic NDIR technology, it directly measures CO₂ concentrations from 0 to 40,000 ppm with an accuracy of ±(30 ppm + 3% of the reading).
Along with CO₂ measurement, the sensor also monitors temperature and relative humidity, providing useful environmental data through a single module. Its compact breakout-board design and I2C interface make it convenient to connect with microcontrollers and IoT development platforms. The SCD43 is well suited for HVAC monitoring, smart building systems, indoor air-quality monitoring, environmental sensing, and IoT applications.

I think OV3660 is a good module,but there should be an option for OV2640 too,cause esp32 cam performs better with OV2640. OV3660 will heat very fast and the streaming will be slow,but it has its own use like it has better resolution and better low light image processing.
It is Amazing and great item in this price
Veri usefull and cheap price from other shopping site, I use this module many project. Thank you robocraze
Nice products
