	78	+GroPoint Air must be used with [[GroPoint Profile>>https://www.gropoint.com/products/soil-sensors/gropoint-profile]]. There are different interface model from GroPoint, users need to choose the one:
	79	+
	80	+* Support RS485 Interface
	81	+* with M12 5pin connector.
	82	+
	83	+Such model in GroPoint Profile is: **2625-N-T-x-M-M **(Where x is different depending on how many levels it detects).
	84	+
	85	+
	86	+== Connect to LoRaWAN Network? ==
	87	+
78	78	Each GroPoint Air is shipped with a worldwide unique set of OTAA keys. To use GroPoint Air in a LoRaWAN network, user needs to input the OTAA keys in the LoRaWAN network server. So GroPoint Air can join the LoRaWAN network and start to transmit sensor data

	163	+GroPoint Air's sensors come in six models:GPLP-2，GPLP-3，GPLP-4，GPLP-5，GPLP-6，GPLP-8.
	164	+
	165	+The amount of temperature and humidity is different for each model, so the payload of each model is different.

	167	+Take GPLP-3 as an example：

	169	+Uplink Payload totals 21 bytes.
