HOBO Weather Stations Aid the Gunnison Sage-Grouse

Conservation groups in Colorado are using a data logging weather station to help protect the rare and beautiful Gunnison Sage-grouse, a chicken-like bird known for its remarkable mating rituals.

A quick temp-accuracy check (ice bath)

We receive many calls requesting information on how to calibrate our data loggers. While our data loggers cannot be calibrated, you can certainly check to see if the data loggers are recording within their specifications. Ideally, testing should be done in a controlled environment. Unfortunately, not everyone has access to this type of environment.

Protecting data loggers from electrical discharge (ESD)

A discharge of static electricity may cause a running data logger to stop recording. Precautions should be taken to prevent this while handling the data logger. Discharges may occur when there is a charge difference between the data logger and a cable being connected to it or when a person touches an exposed jack.

Data loss and recovery

There are two common reasons for data loss:

Drying a wet circuit board

If possible, remove the board from the case and the battery from the board. Dry the board completely using a hair dryer. If the board was exposed to salt water, rinse the board with fresh water and then dry the board. You may try inserting a new battery and downloading the data. If you are unable to access the data, or see any sign of corrosion or tarnishing on the board, contact the place of purchase for a return number. The data may be retrievable, and the data logger may be repairable. Charges will apply and are dependent on the amount of damage.

Possibility of exposure to chemicals or chemical vapors

This is dependent on the data logger you are using and the chemical and/or concentration of the chemical to which the data logger is exposed. Many chemicals will have an adverse effect on the data loggers and/or the sensors that the loggers utilize. Contact your authorized sales representative with questions regarding specific chemical contact with the data logger that you are using.

Maximum sensor cable length

The entire network (all sensors combined) cannot exceed 100 meters. As long as your total cable length is below this, it does not matter how you designate the individual cable lengths. It is important to insure that the connections are weatherproof.
