HOBO by Onset MX1104 Analog/Temp/RH/Light
- BLE communications for wireless data offload
- 16-bit resolution for highly accurate measurements
- Stores 1.9 million measurements for longer deployments between offloads
- New Self-Describing sensors with automatic configuration for fast deployment
The HOBO MX1104 multi-channel data logger measures and transmits temperature, relative humidity, and light intensity data wirelessly. It also includes an external analog input to attach a variety of additional sensors.
This self-contained wireless data logger lets you use your mobile device and Onset’s free HOBOmobile® app for iOS to access data, at any time, over a 100-foot range via Bluetooth Low Energy (BLE) technology. You can configure the logger, read out data, view data in graphs, check the operational status of loggers, configure alarm notifications, and share data files – all with no dedicated equipment beyond a mobile device. And if used with the new MX Gateway, you can remotely access your data in Onset’s cloud-based HOBOlink® software.
Supported Measurements:
4-20mA, AC Current, AC Voltage, Air Velocity, Carbon Dioxide,Compressed Air Flow, DC Current, DC Voltage, Dew Point,Differential Pressure, Gauge Pressure, Kilowatts (kW), LightIntensity, Relative Humidity and Temperature
