DAVIS Pluviometer for HOBOnet network in inches RXW-RGE-868

The rain sensor HOBOnet records the precipitation by increments of 0.01 inch. Sensors wireless HOBOnet communicates the data directly to the HOBO RX3000 or to hOBO MicroRX station, or transmit data via other wireless sensors to the central station. They are preconfigured and ready to deploy, and data are accessible via HOBOlink, the innovative cloud software platform of'Onset.
