Outdoor Environmental Monitoring


FilesThruTheAir™ data loggers can be used for many environmental research applications, ranging from individual loggers recording locally, to multiple devices used for large-scale monitoring. Their reliability and high memory capacity means they can be deployed for long-term data collection in remote areas.

Outdoor Environments

Monitor remote outdoor locations with a USB data logger, durable enough to withstand the elements and with a typical battery life of two years, the device can be left to record data without any further efforts. Once plugged into a PC, data reports can be constructed to show trends in conditions. 


FilesThruTheAir™ data loggers can be used to monitor the climate in the habitats of various wildlife. Monitoring temperature or humidity can reveal trends that might help in investigating animal behaviours in hibernation, nesting and relocation. 

USB Temperature & Humidity Data Loggers

The temperature and humidity range of USB connected devices are low-cost and hardwearing, ingress from water and dust to IP67. Simply leave to log in the desired outdoor space and plug the device into the PC. Once downloaded, data can be graphed, printed or exported for further analysis on a PC via the free EL-WIN-USBsoftware package. Data can also be downloaded directly onto the EL-DataPad touch screen data collector.

With screenless and LCD screen options, the EL-USB-2 and EL-USB-2-LCD devices log over a temperature range of -35 to +80°C with an accuracy of 0.55°C (high accuracy versions available, click below).

Carbon Monoxide Data Logger

The EL-USB-CO data logger measures and stores up to 32,510 Carbon Monoxide (CO) readings over a 0 to 1000 ppm measurement range and -10 to +40°C (14 to +104°F) operating temperature range. The high-accuracy version, the EL-USB-CO300, measures over a 0 to 300 ppm measurement range accurate to ±5ppm. The user can easily set up the logging rate and start time, and download the stored data by plugging the module straight into a PC's USB port and running the purpose designed software. The data can then be graphed, printed and exported to other applications.

Remote Temperature & Humidity Logging

The EL-MOTE-TH & TH+ are discreet, screenless data loggers that connect to the EasyLog Cloud for remote monitoring, ideal for outdoor applications due to its IP67 rating. Simply set up within a WiFi-range or cellular router and leave it to log automatically to the EasyLog Cloud and send email alerts to the user if certain temperature and humidity levels are breached. Ideal for single sensor systems, or a complex array of multiple sensors spanning various locations across the globe, all communicating with the same online account.
