The Onset RXMOD-W1 Water Level Sensor Module offers users the ability to monitor water level, pressure, and temperature, as well as barometric pressure, with the HOBO RX3000 Remote Monitoring Station. It is configured through HOBOlink, Onset's cloud-based software. For water level applications, a HOBO RX3000 station, water level sensor cable (CABLE-RWLMOD-XXX), and water level sensor (MX2001-0X-S or MX2001-0X-Ti-S) are required (and not included).
