I'm a mushroom farmer working with Arduino and Raspi to build a climate controlled growing unit and was curious if anyone knows of a single sensor that will read temperature, humidity and CO2 ppm. If not, anyone have thoughts on the effort it would take to build one? Thanks!

What have you found with Google so far?

I've found a temp/humidty sensor and a CO2 sensor, but none that do all 3 in one sensor.
