MH-Z14 or Z19. But this is just the sensor, you'll need an Arduino/ESP/Rpi too.

- AYBABTME 8y agoWhat's particular about these sensors? I've been researching technologies to monitor plant growth and haven't yet looked into CO2 sensors, hence my asking. Do they come in an IC package?
- gsich 8y agoThey use optical measurement, are reasonable in pricing. Outputs are UART, PWM and analoge. They have pins with 2.54mm spacing if that helps you.
