-- Fast Data Collection and Retrieval for Remote Monitoring Applications
- To begin searching for the right product, always keep in mind your starting point–what do you want to accomplish? With such a wide range of options open to you, critical details such as knowing how many and what types of inputs are required along with how often readings need to be taken.
- You'll also want to take into account whether the data logger must be equipped with external sensors or utilize built-in sensors for temperature or humidity.
- The type of sensors being recorded is also critical in the decision process. For instance, if you're planning to use thermocouples, the remote monitoring logger must support TC inputs.
- Most data loggers can record at a rate up to about 1Hz (once per second), although many faster recording frequencies are available. This can be easily determined the amount of data storage required by multiplying the number of channels by the sample rate and recording duration, given in this quick formula:
Total Number of Points = Number of Channels x Sample Rate x Recording Duration
5. Where are you planning to use the logger? If the logger will be used in the field, you'll definitely want to consider a ruggedized device that can survive hazardous working conditions like dust, and dirt and also offers a wide range of operating temperatures.
6. If this is for remote monitoring, how the logger will be powered? Is there AC power at the site or will you need a solar panel or battery-operated device for extended operation? Systems such as the Infinite ADU provide very low power operation allowing extended operation – up to 5 years – from a single Li battery.
7. Does the system need some sort of local display? Some data loggers have a built-in LCD display with a backlight that shows status and measurement data whether underground or outdoors.
8. Is this going to be a permanent installation with static requirements or do you anticipate the need to expand to add more inputs or sensors in the future? If you anticipate future expansion or possibly re-using the logger after the project is complete, search for data loggers with a modular design so you can expand or add other capabilities when needed.
9. How remote is the location where you're collecting the data? If you just need to download data, a data logger with support for a USB memory stick serves as the fastest way to get your data.
10. When it comes to software, look for a user-friendly interface that enables an easy setup. Many loggers come with free software for configuration, monitoring, and data retrieval, such as the dEX program that comes with every dataTaker (https://dataloggerinc.com/products/datataker/) logger.
