CO2 and Pressure
CO2 and pressure control board is designed for measuring CO2 concentration in air and for keeping the positive air pressure in the button mushroom (champignon, agaricus) growing room.
The air with CO2 is pumped out of the growing room and supplied through the air tube and air filter to CO2 transmitter. CO2 transmitter measures the level of CO2 concentration up to 5000 ppm. The detected value is transformed into an analogue 4-20 mA (or 0-10 V on request) output signal and transmitted to a mushroom controller.
Functions
- Measurement the difference of the air pressure in a growing room and a corridor
- Automatic control of air overpressure in a growing room
- Noise filtering
- Alarm signal when the pressure is out of range
- Data transfer to a PC via RS485 communication interface
