e humidity
The bottom of the Greenhouse Sensor module board includes a
combination temperature and humidity sensor. Temperature is
measured on the Celsius, Fahrenheit, and Kelvin scales. Relative
humidity is reported as a percentage representing the ratio of the
partial pressure of water vapor to the saturated vapor pressure.
Light
Light
The top of the Greenhouse Sensor module board includes a light
intensity sensor. The sensor needs to be positioned near the center of
the EcoChamber lid to measure the light intensity provided by the
PASCO Grow Light (PS-3347). Light intensity is reported as a relative
percentage.
Soil moistur
Soil moisturee
Soil moisture is measured in units of volumetric water content (VWC)
percentage. Volumetric water content is the ratio of water volume per
unit of soil volume. The sensor provides VWC measurements for three
types of soil:
• Clay
Clay
Use this measurement for soil that is smooth to the touch and
easily compacted. This type of soil will be sticky and clump
together when wet but crack as it dries.
• Sand
Sand
Use this measurement for soil consisting of coarse and gritty
particles.
• Loam
Loam
Use this measurement for soil consisting of a mixture of sand, clay,
and silt. Loam is often high in dark, composted material and is
found in most commercial garden soils.
The entire probe must be covered in soil and it is best to maximize
contact between the probe and the soil. Any air gaps or excessive soil
compaction around the probe can affect the readings.
