EI-1050

Digital Temperature / Humidity Probe

The EI-1050 uses two digital lines on the LabJack U12 (IO0 and IO1) to retrieve temperature and relative humidity measurements. Featuring the Sensirion SHT11 sensor, it provides 14-bit temperature readings and 12-bit humidity readings. An enable line is provided allowing multiple EI-1050 probes to be connected to a single LabJack U12. Measurement range is -40 to 120 degrees C for temperature and 0 to 100% for humidity. Accuracy is +/-0.5 degrees C (@ 25 deg C) and +/-3.5%. With LabJack U12 firmware version 1.10 or higher (Feb 2003 or later), it takes about 230/75 milliseconds to get a temperature/humidity reading. With earlier firmware versions it takes about 2 seconds to get one temperature or humidity reading. For the LabJack U12 only.
