What is it?

This AgroSense 4-Channel LoRaWAN® Relay is designed for LoRaWAN remote control from cloud via LoRaWAN Class C. It is based 4 high-load relays that support max 20A@125V AC, make it possible for users to control 4 channel loads, such as Fan/door/lights, On/Off, via standard LoRaWAN Class C from Cloud service. Also 2 channel analog inputs(0~5V) support common sensor inputs, and on-board temperature and humidity sensor(AHT20) for field application environment detection, for fire/dangerous detections.

Different with Class A, LoRaWAN® V1.0.3 OTAA Class C standard keep stable connection from nodes to gateway, suitable for applications that need long-term /stable connection and more frequent data uplink/ relative quick feedback, with disadvantage of higher power consumption. This AgroSense 4-Channel LoRaWAN® Relay supports common 2 data modes:

• Data Uplink: It uplink the relay status/analog inputs/ temp& humidity sensor data to gateway with dedicated time interval (default 10s and can be set to 24h max with data downlink)

• Data Downlink: Users can send downlink commands from cloud server, to control relays, adjust data reporting intervals, and perform scheduled tasks—making it highly adaptable to various automation needs.

This Module supports global frequency bands (EU868/US915) and works seamlessly with platforms such as TTN, Datacake, and CloudStutio to enable data upload and remote control.

Besides, it has Local storage for max 3,300+ records, ensures critical data is retained during connectivity gaps.

General Parameters

Wireless Parameters

Physical Parameters

AgroSense is a series of Makerfabs wireless LoRaWAN® sensors.

It can cover a transmission range of 2km in urban scenes and 5km in line-of-sight scenes while keeping lower power consumption during the transmission process. Together with a replaceable battery that supports up to 1 years of usage and an industrial IP68 enclosure. It supports -40 ~ 85℃ operating temperature and can be deployed in harsh environments. AgroSense is compatible with LoRaWAN® V1.0.3 protocol and can work with LoRaWAN® gateway.

With LoRaWAN® gateway, LoRaWAN® sensor report the result to LoRaWAN® networks, such as The Things Network and DataCake, with simply inputting DEV EUI/ APP EUI/ APP Key:

• DEV EUI: Unique identification of device，authorized by IEEE；
• APP EUI: Unique identification of application；
• APP Key: One of the join network parameters on OTAA mode, calculated by DEVEUI；
