Humidity Control: Sensor Placement
The placement of a sensor is very important and the importance of this consideration often neglected by many growers. So, growers need to consider this placement carefully as it will be how the system perceives and adjusts the environmental conditions.
Growers should determine what they think is the best placement and then observe the sensor and system in action and be willing to make adjustments if necessary. This is in part why this sensor has been mounted on a tall bamboo stake with a zip-tie as this can allow for easy adjustments if needed. Luckily this sensor has a 15ft. cord so there is a lot of freedom to ensure the “best” location is found.
As can be seen in the picture the sensor is place about 5ft in from the edge of the plant and not directly below a misting nozzle. In addition, it is also at plant height which is just above the leaf surface to ensure the environment the plant is being exposed to is closest to what the sensor is reading.
This sensor also has a photo sensor so it knows day vs night so placing it above the leaves and ensure it is not being blocked is especially important as different target humidity levels can be set for day vs night.
