Short summary
Lower-cost optical sensors, which can be left outdoors, are often used to provide information regarding plant photosynthetic activity. A lower-cost sensor was compared with an expensive instrument to see if the data collected were comparable. Both instruments were able to track changes in photosynthetic activity, but the values recorded by each were different. This can cause difficulties when comparing data across space and time. We provide advice on how best to use these sensors in the field.
