Adapter for external supply of IoT sensor with radio output to Sigfox network
The SP014 adapter is designed to be used as an accessory for battery powered transducer with radio output to Sigfox net (Wx8xx series).
When installed in place of an existing battery, the transducer will be extended with an external power input. The transducer can then be powered from a 5V DC power adapter, an external large capacity battery, or a suitable solar battery system with a backup battery. The transducer with mounted adapter is designed for indoor or covered environment.
Adapter can be used for models W0810, W0811, W0832, W0850, W3810, W3811, W7810
