HOBO MX1104 Analog/Temp/RH/Light Data Logger

Product Options
MX1104

Overview

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 HOBOconnect app 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.

Specification

Temperature Sensor (MX1104)
Range -20° to 70°C (-4° to 158°F)
Accuracy ±0.20°C from 0° to 50°C (±0.36°F from 32° to 122°F)
Resolution 0.002°C at 25°C (0.004°F at 77°F)
Drift <0.1°C (0.18°F) per year
RH Sensor* (MX1104)
Range 0% to 100% at -20° to 70°C (-4° to 158°F); exposure to conditions above 95% may temporarily increase the maximum RH sensor error by an additional 1%
Accuracy ±2.5% from 10% to 90% (typical) to a maximum of ±3.5% including hysteresis at 25°C (77°F); below 10% and above 90% ±5% typical
Resolution 0.01%
Drift <1% per year typical
Response Time (MX1104)
Temperature 11 minutes in air moving 1 m/s (2.2 mph)
RH 30 seconds to 90% in airflow of 1 m/s (2.2 mph)
Light Sensor (M1104)
Range 0 to 167,731 lux (15,582 lum/ft2)
Accuracy ±10% typical for direct sunlight (see Light Measurement on page 4 for more details)
Logger
Operating Range -20° to 70°C (-4° to 158°F)
Radio Power 1 mW (0 dBm)
Transmission Range Approximately 30.5 m (100 ft) line-of-sight
Wireless Data Standard Bluetooth Low Energy (Bluetooth Smart)
Logging Rate 1 second to 18 hours
Logging Modes Fixed interval (normal, statistics) or burst
Memory Modes Wrap when full or stop when full
Start Modes Immediate, push button, date & time, or next interval
Stop Modes When memory full, push button, date & time, or after a set logging period
Restart Mode Push button
Time Accuracy ±1 minute per month at 25°C (77°F)
Battery Type Two AAA 1.5 V alkaline batteries, user replaceable
Battery Life 1 year, typical with logging interval of 1 minute and Bluetooth Always On enabled; 2 years, typical with logging interval of 1 minute and Bluetooth Always On disabled; and temperatures between 0° and 50°C (32° and 122°F). Faster logging intervals and statistics sampling intervals, burst logging, remaining connected with the app, excessive downloads, and paging may impact battery life.
Memory 4 MB (1.9 million measurements, maximum)
Full Memory Download Time Approximately 4 to 15 minutes depending on the mobile device; may take longer the further the device is from the logger
LCD LCD is visible from 0° to 50°C (32° to 122°F); the LCD may react slowly or go blank in temperatures outside this range
