The GP-BTDL Bluetooth SDI-12 Data Logger is wireless data logger that allows you to retrieve data through your Android device. It is left on site to reliably collect data from your GroPoint Soil Sensors or other SDI-12 sensors, allowing you to access the data when convenient. Our data logger will collect and store up to 4MB of environmental data, such as soil moisture, temperature, EC and more.

The free GP Reader app (available for Android devices only) is used to check current conditions, download data and set up the sensor sampling interval (from one minute to 12 hours). With the app open on your smartphone, simply push the button on the GP-BTDL Bluetooth SDI-12 Data Logger to wake it up and automatically establish a wireless connection. Tap the Download button in the app to download all logged data. You can also check the current battery level of the Bluetooth Data Logger.

The GP-BTDL Bluetooth SDI-12 Data Logger connects to up to 10 SDI-12 sensors (with the 4-Port SDI-12 Expansion Bar) with 200ft of cable as per SDI-12 specifications. For more information on sensor configurations, see our data logger user manual. Sensors must terminate in an M12 connector. Works with most V1.3 SDI-12 Sensors.

Data is stored in non-volatile memory and is retained even if the battery fails. The memory can hold up to 200,000 measurements.
