MH-Z19 CO2 Sensor - Home Assistant

The MH-Z19 is a small non-dispersive infrared sensor that can measure CO2 level. High CO2 levels can lead to drowsiness, poor concentration, loss of attention or increased heart rate. The CO2 level outside is around 400ppm, but inside levels can reach between 1000 and 5000 ppm. High CO2 levels indicate that you should increase ventilation.

Live Well Operation Z18 | Nitro & Tracker Boat Owners Forum

· With it open water will enter the livewell, 6" maybe, depending on your load in the boat since the inlet and bottom of the livewell are below the water line when on the water. At the back you have a drail and an inlet for the incoming water (should have a screen installed over that intake port). The other one is simply a drain. You shouldn't have to put a plug in the bottom of the livewell tank unless …
