What does the system measure in a drying room?

Air temperature and relative humidity, logged continuously. The THS-100 sensor covers -40 to +80°C and 0 to 100% RH, with an accuracy of ±0.3°C and ±3% RH. Multiple sensors can be placed at different heights and positions, because a drying room is rarely uniform from floor to ceiling.

Can it control the equipment or does it only record?

Both. The Omni Genesis controller supports up to four independent relay outputs, so it can switch a fan, a heater, a dehumidifier and a humidifier against your setpoints. You define the target and the hysteresis band, and the controller does the switching.

What happens if the internet connection drops?

The control logic runs locally on the controller, not in the cloud. Relays keep switching against your setpoints while the connection is down, and readings sync automatically once it returns.

Which crops is this used for?

Any produce dried or cured in a controlled room. That includes cannabis, dates, herbs, seeds, tobacco and hops. The hardware is the same; what changes is the setpoint and the tolerance band you choose for the crop.

How many rooms can one system cover?

Sensors are addressable on an RS-485 Modbus bus, so a single controller covers multiple points in a room, and multiple controllers report into one cloud account. Each room can carry its own targets, alert thresholds and logs.

Drying Room Monitoring and Humidity Control

A drying room is won or lost on humidity. Agrinovo measures temperature and relative humidity continuously, alerts the moment either leaves the band you set, and switches your fans, heater and dehumidifier through the controller. Used for cannabis, dates, herbs and seeds.

Measure both variables, then act on them

Recording a bad dry is not the same as preventing one. The controller does both.

One bad night costs the batch

Humidity climbing overnight is the failure nobody sees until the room is opened. Continuous logging plus an alert on the first reading outside the band turns that into a phone notification instead of a loss.

A record of every batch

Every reading is stored and exportable, so each batch carries a full temperature and humidity history. Useful for proving process consistency and for working out why one run came out better than another.

Rooms are not uniform

Temperature and humidity vary between floor and ceiling, and near the extraction point. Sensors are addressable on the Modbus bus, so a room can carry several measurement points rather than one and a hope.

Control that survives an outage

The control loop runs on the controller itself, not in the cloud. If connectivity drops, the relays keep working to your setpoints and the readings sync when the link returns.

How the control loop works

Four parts, wired once.

01

Sense

A THS-100 temperature and humidity sensor reports over RS-485 Modbus RTU. Probe housings are available for high dust and washdown environments.
02

Decide

The Omni Genesis controller compares each reading against your setpoint and hysteresis band, so equipment does not chatter on and off around the threshold.
03

Act

Up to four relay outputs switch the extraction fan, dehumidifier, humidifier and heater. Each output has its own rule.
04

Log and alert

Readings stream to the cloud dashboard, and anything outside the band raises an alert. History is exportable per room and per batch.

For the wiring detail, setpoint and hysteresis walkthrough, see the drying room humidity control guide.

What gets dried in these rooms

Same hardware, different targets.

Cannabis

Drying and curing rooms, where a narrow humidity band over a long hold decides the quality of the batch.

Dates

Hydration and drying rooms, where the target moves through the cycle rather than staying fixed.

Herbs and spices

Low temperature drying where overshooting costs colour and aroma.

Seeds and grain

Drying to a storage moisture target, then holding it without over-drying.
