» SX 13: Get Temperature

This example shows how to get the temperature value that this module provides.

Required Materials

1 x Waspmote PRO
1 x Battery
1 x MiniUSB wire
1 x SX1272 module (LoRa)

Notes

- The SX1272 module is provided with a special 4.5 dBi antenna, which enables maximum range. The only exception is Smart Parking; in this case the antenna is smaller, 0 dBi, to fit inside the enclosure.
- It is not recommended to work without an antenna screwed to the module. The module could be damaged due to RF reflections.
- The SX1272 module can only be used in special Waspmote units which have been modified to drive the SPI pins to SOCKET0. (only SOCKET0 is available for SX1272)
- This module does not save the configuration. So, the network settings as the mode or the channel MUST be configured every time it is switched on.
- This example can be executed in Waspmote v12 and Waspmote v15
