Drying Room Monitoring and Humidity Control
Agrinovo measures air temperature and relative humidity at several points in each drying or curing room, sends an alert when a reading stays outside the range you set, and switches fans, heaters or dehumidifiers through a relay when humidity or temperature crosses a threshold.
Humidity in a drying room changes with the batch and with the position in the room
In controlled drying the product gives its water to the air, so relative humidity rises while a fresh batch dries and falls when the extraction fan runs. Temperature and humidity also differ between the floor, the ceiling and the air near the extraction point, so a single sensor on one wall describes one spot in the room.
Humidity that climbs overnight raises an alert
Most rooms are not checked between evening and morning. When humidity stays above the range you set for longer than you allow, the people on the account are alerted, and the history shows the hour the rise began.
Sensors at several heights show how even the room is
Temperature and humidity sensors share one RS-485 cable, each with its own address. One controller port reads a sensor near the floor, one under the ceiling and one by the extraction point.
Every batch keeps its own temperature and humidity record
Each reading is stored with its time. When one batch comes out better than the previous one, you compare the two drying records hour by hour.
What is installed in a drying room
-
Temperature and humidity sensors
THS-100 sensors measure -40 to +80°C and 0-100% RH, non-condensing, and report over RS-485 Modbus. Housings are available for dusty rooms and for rooms that are washed down.
-
The Omni Genesis controller
The Omni Genesis has 4 ports, and each port either reads sensors or provides a switched 12V or 5V output. It reports over 4G-LTE or Wi-Fi and runs on a rechargeable battery, so it keeps measuring during a power cut.
-
Fans, heaters and dehumidifiers on a relay
A port set as a 12V output drives an external relay, and the relay switches the fan, heater or dehumidifier. You set the humidity or temperature threshold for each output in the cloud. Sensors and outputs share the same ports, so the number of devices one controller switches depends on how many ports its sensors use.
-
A range and a reporting interval for each room
Each room gets a name, a minimum and maximum for temperature and humidity, and an allowed time outside them. The controller reports as often as you choose, down to once a minute.
Background on humidity targets and drying room equipment is in the drying room humidity control guide.
What the dashboard shows and who is alerted
Readings grouped by room
Current temperature and humidity at every measuring point, with each room shown separately.
Alerts by SMS, email, call or app
You decide in the cloud which readings raise an alert and who receives it: by SMS, email, phone call or app notification.
Export to Excel
Any room and any date range can be exported to Excel and filed with the batch paperwork.
Products dried in these rooms
Cannabis
Drying and curing rooms that hold humidity in a narrow range for a long period.
Dates
Hydration and drying rooms, where the target temperature and humidity change during the cycle.
Herbs and spices
Drying at low temperature, where excess heat costs colour and aroma.
Seeds and grain
Dried down to a storage moisture target and then held there without over-drying.
