The HOBO RX3000 Remote Monitoring Station is a research-grade data logging weather station that combines greater measurement flexibility and an on-board LCD display in a rugged, easy-to-deploy package. The RX3000 provides continuous logging for a broad range of energy and weather monitoring applications with up to ten smart sensors and optional relay and analog sensor modules. Supported measurements include temperature, relative humidity, dew point, solar radiation, PAR, rainfall, wind speed, wind direction, soil moisture, barometric pressure, leaf wetness, 4-20mA, voltage input, and pulse input.

Data from the RX3000 station is transferred at regular connection intervals to HOBOlink web-based software where you can check the latest conditions, view graphs, configure sensors and alarms, download your data, or schedule data delivery via email or FTP. Check out Instrumart's RX3000 HOBOlink for an example of what it will look like.

Inside its weatherproof enclosure, this durable station has a built-in LCD screen to check the current system configuration and status, start and stop logging, add and remove smart sensors, and connect to HOBOlink on demand. Up to three individual relays can be activated on the optional relay module while the optional analog module has four analog inputs that support excitation power, scaling, and statistics measurements. Both of these easy-to-install modules can be configured with HOBOlink.

The RX3003 cellular communication data logger is available as a weather station starter kit that includes a 1-year data plan (choice of Global Limited Plan or Global Max-Connect Plan).

Application Notes

Here's how some of our customers used this product.

Rooftop HVAC Monitoring

The Background: An engineering firm is conducting an analysis on a rooftop HVAC installation to monitor for energy efficiency.

The Problem: The firm needs a multiparameter logger to monitor temperature, pressure and power usage. Additionally, the information needs to be transmitted from the monitoring site to the firm's base 3 hours away.

The Solution: We suggested the HOBO RX3000 with a HOBO TMB Series 12-Bit Temperature Smart Sensor, HOBO T-MAG-SCT Series AC Transformer, HOBO T-VER-E50B2 Power / Energy Meter, and an AST46PT Sealed Pressure / Temperature Transmitter. The RX3000 is a multiparameter logger that can be configured with cellular, WIFI or Ethernet communications which satisfies all of the customer's concerns.
