Typical Applications

Applications include:

• Datalogger with multiple integrated sensors to measure PAR (SM-500) or ePAR (SM-600), air temperature, humidity, vapor pressure deficit and dewpoint, CO2 concentration, barometric pressure, daily light integral, and photoperiod.

• Accurate environmental measurements in controlled environments, such as greenhouses and growth chambers

• Monitoring specifications that are critical for plant health, growth rate, photosynthesis levels, plant morphology, and crop steering
