Introduction
R720F series is a Class A device based on LoRaWAN
TM
protocol of NETVOX and is compatible with LoRaWAN protocol.
It is a wireless communication device that can detect the level of hand wash or the water leakage. The detected data will be
transmitted to other device for display via wireless network.
The hand wash detection devices
are R720FLO,R720FLD,R720FU. The devices are connected with two electrode rods.
The shape and orientation of electrode rod of can be selected according to the needs, and the electrode rode can be trimmed to
the required length by self according to the demand.
The water leakage detection device
is R720FW.
Hand Wash Detection
1.
Regularly check the current voltage and state of hand wash according to the configured time.
2.
When the device detects the change in the current state of the hand wash, it will report a data packet of the current
voltage and state of the hand wash.
3.
Press the function key to immediately detect the current voltage and state of the hand wash, and a currently detected
data packet will be reported.
Water Leakage Detection
1.
Regularly check the current voltage and state of water leakage according to the configured time
2.
When the device detects the change in the current water leakage state, it will report a data packet with the current
voltage and state of water leakage.
3.
Press the function key to immediately detect the current voltage and state of water leakage, and a currently detected data
packet will be reported.
LoRa Wireless Technology:
LoRa is a wireless communication technology dedicated to long distance and low power consumption. Compared with other
communication methods, LoRa spread spectrum modulation method greatly increases to expand the communication distance.
Widely used in long-distance, low-data wireless communications. For example, automatic meter reading, building automation
equipment, wireless security systems, industrial monitoring. Main features include small size, low power consumption,
transmission distance, anti-interference ability and so on.
LoRaWAN:
LoRaWAN uses LoRa technology to define end-to-end standard specifications to ensure interoperability between devices and
gateways from different manufacturers.
