    Monitor conditions from anywhere with HOBOnet Temperature Sensor

    A cost-effective and scalable solution for web-enabled monitoring of air, soil, and water temperatures. 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. They are preconfigured and ready to deploy, and data is accessed through HOBOlink, Onset's innovative cloud software platform.
