HOBO MX1104 – Onset

Data logger with internal sensors for temperature, relative humidity, light and 1 multi-channel input (4-20 mA/0-2,5 V/0-5 V/0-10 V/0-24 V), which measures and transmits data wirelessly from a variety of sensors to your mobile device via Bluetooth technology

Pedak - Onset HOBO MX1104

The MX1104 wireless data logger can be used with your mobile device or Windows computer and the free HOBOconnect app to access data, at any time over a 30 metres range via Bluetooth Low Energy (BLE) technology. You can configure the logger, read out the data, view the data in graphs, check the operational status of loggers, configure alarm notifications and share the data files – all with no dedicated equipment beyond a mobile device. If the data logger is used with a MX gateway, you can remotely access your data in the cloud-based HOBOlink software.

This data logger has a 16-bit resolution for highly-accurate measurements and can store up to 1,9 million measurements for longer deployments between offloads. You can use the data logger with new self-describing sensors with intelligent configuration for fast deployment and it is compatible with existing sensors for a wide range of indoor monitoring. An audible and/or visual LCD-screen alarm will notify you if a sensor becomes unplugged or a reading exceeds set thresholds.

This is a data logger which operates in an indoor environment and the MX1104 data logger supports the following 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), light intensity, relative humidity and temperature.
