1. Introduction
1.1 Profile
AN-203A is a wireless water level monitor complied with LoRaWANTM. It is
equipped with piezoresistive water level sensor and packaged with low-voltage
injection molding process. The performance is stable and reliable. With LoRa spread
spectrum communication technology, omnidirectional external antenna design can
better transmit and receive wireless signals and improve the communication distance
of wireless transmission. It has low power consumption. With built-in large capacity
battery, its lifespan is more than three years. The data gathering box is robust with
IP67 enclosure. It can be used in indoor and outdoor.
AN-203A is simple to install and maintain. It can be installed flexibly in the way of
pole-mounting or wall-mounting on the vertical pole, lamp pole and building wall.
Application
Water level measurement and control in property fire control, industry, petroleum,
power plant, mine, urban water supply and drainage, hydrologic exploration and etc.

3. How to work
3.1 Operation principle
The sampling interval time can be configured by user. When the water level data
gathered is higher than or equal to the upper threshold (400cm by default,
configurable) or lower than or equal to the lower threshold (100cm by default,
configurable), the current water level value will immediately trigger the alarm. And
the current water level value will be reported regularly according to the set alarm
reporting interval time. When the water level returns to normal, the water level value
will be reported immediately. The heartbeat packet interval time is calculated from the
time when the trigger event happens.

3.2 Turn on/off
Turn on: Gently touch inductive switch for 5s with your fingers, the buzzer will
keep ringing. Leave it for about 1s later. Then touch it twice with your fingers
until two Di sounds heard. At this time, the device boots up and can work
normally.
Reset: Touch the inductive switch with fingers for 5s to reset after it boots up.
Join network: The buzzer beeps 3 times indicating it joins network.

4. Configuration
4.1 Precaution
For device normal operation and detection accuracy, please pay attention to the
following matters before configuration:
Before configuration, please contact our technical staff for the relevant software
and manual.
For wireless configuration, it should be done within the signal coverage area of
the wireless serial port module.
4.2 Tool list
Note: For configuration, you can use wireless configuration tool (wireless
configuration) or USB to TTL cable (cable configuration), but here we choose to tell
customer how to do wireless configuration.
