Description

From the listing uploaded by “appupdater”.

The SDI-12 explorer is designed to assist in configuration and testing of environmental monitoring systems and sensors that use the SDI-12 communications protocol. Using the SDI-12 explorer you can read sensor values, interrogate sensor identifications, scan the SDI-12 bus for sensors, change SDI-12 sensor addresses, send custom extended SDI-12 commands and snoop on SDI-12 communications between the data logger and sensors. NOTE: THIS APP REQUIRES A NIWA BLUETOOTH TO SDI-12 EXTENDER AVAILABLE FROM NIWA INSTRUMENT SYSTEMS. [email protected] The NIWA Bluetooth to SDI-12 Extender provides the hardware for communications between your Android device and the SDI-12 sensor using Bluetooth. The NIWA Bluetooth to SDI-12 Extender is fully self contained and features an internal Lithium-ion battery to provide power to the interface and also provide an external 12V supply for powering sensors under test. The NIWA Bluetooth to SDI-12 Extender also provides a true RS232 level serial output for communications with RS232 capable data loggers
