#28640 - RE: low cost CO2 gas sensor |
For mushroom growing you require sensing around the 1500ppm area and it would be difficult to sense using an absense of O2.
Infrared sensors can be bought for around $100 us and are the only real solution, along with an solenoid air demultiplexer for multiple rooms. Chris |
