Measures light intensity for frequencies relevant to photosynthesis. HOBOnet wireless sensors communicate data directly to the HOBO RX3000 or the HOBO MicroRX station or pass data through other wireless sensors back to the central station. These sensors are preconfigured and ready to deploy, and data is accessed through HOBOlink, Onset's innovative cloud software platform.
