1. Product Introduction
1.1 Introduction
The S2120 Weather Station monitoring Air Temperature, Humidity, Wind Speed/Direction,
Rainfall, Light, UV Index, and Barometric Pressure measurements provides you with
hyperlocal weather at your fingertips.
Perfect for home, office, or business use, this professional home weather station allows you
to monitor your backyard weather conditions from anywhere. Protect your family, the house,
and your garden with minutes updates in weather changes. Additionally, S2120 weather
stations also support applications in agriculture, meteorology, urban environmental
monitoring and other scenarios.
Smart and connected, the S2120 provides data on your phone, tablet, computer browser. We
provide the SenseCAP Mate App, users can quickly view data via the App. We also provide
SenseCAP Portal to manage your weather station through the Web page.
The S2120 is a standard LoRaWAN sensor that can be connected to any LoRaWAN
gateway and service.

precision screwdriver.
4.3 Install the Rain Gauge
Install the rain gauge funnel and rotate clockwise to lock the funnel to the weather station.
4.4 Power Supply Mode
Weather stations do not contain batteries, so additional batteries are required.
The sensor is powered by a combination of solar panels and batteries. When the solar panels
are working, the device is powered by the solar panels; When solar energy is low, it is
powered by batteries.
Different types of batteries affect the operating temperature range of the sensor. In addition,
Different number of batteries determinesthe battery life ofthe sensor.

Battery schemes
Advantage and disadvantage
3 * 1.5V AA alkaline battery,
built-in battery box
The operating temperature of the sensor depends on the
operating temperature of the battery. If the alkaline battery
is used, the operating temperature range is-20 ~ 60℃.
3 * 1.5V AA Lithium battery,
built-in battery box
If the alkaline battery is used, the operating temperature
range is -40 ~ 60℃.
6 * 1.5V AA alkaline battery,
external battery box
It will last twice as long as 3 x batteries.
6 * 1.5V AA alkaline battery,
external battery box
It will last twice as long as 3 x batteries.
Note:
The battery box does not have the charging capability. Therefore, non-rechargeable batteries
are recommended. If you choose a rechargeable battery, you need to take out the battery
and charge it separately after the battery is exhausted.
4.4.1 Install the battery with built-in box
Step 1: Unscrew the battery door at the bottom of weather station.
Step 2: Insert the 3 AA batteries according to the +/- polarity indicated. Then close the battery
door.

Step 3: Tighten the battery door screw. Once the installation completed, the red LED
indicator at the bottom of the weather station will be flashing.
4.4.2 Install the battery with external box
Step 1: Slide the battery box lock switch to unlock position. Push to open the battery box
door according to the arrow direction.
Step 2: Insert the 6 AA batteries according to the +/- polarity indicated.

Step 5: Insert the dummy battery to the battery compartment, make sure the “OUTSIDE”
marking faces outside and the+/- polarity in correct orientation.
Step 6: Replace with the battery door which come along with the external battery box, then
tighten the battery door screw. Once the installation completed, the red LED indicator at the
bottom of theweather station will be flashing.
Note:
If the dummy battery is not installed in correct orientation, battery power connection will be
failure and the LED indicator will not be flashing.
Step 7: Use the cable ties to mount the battery box onto the mounting pole.

6.3 Configure parameters through App
6.3.1 Select the Platform and Frequency
S2120 weather stations are manufactured to support universal frequency plan from 863MHz
~928MHz in one SKU. That isto say, every single device can support 7 frequency plans.
Platform
Description
SenseCAP for The
Things Network
Default platform.
It must be used with SenseCAP Outdoor Gateway
(https://www.seeedstudio.com/LoRaWAN-Gateway-EU868-p-
4305.html ). SenseCAP builds a proprietary TTN server that
enables sensors to be used out of the box when paired with an
SenseCAP outdoor gateway.
SenseCAP for Helium
When there is the Helium network around the user, data can be
uploaded using sensors. Devices run on a privateHelium console
of SenseCAP. Users do not need to create devices on Helium
console, right out of the box.
Helium
Connect Sensor to public Helium console.
The Things Network
Connect Sensor to your TTN(TTS) server.
Other Platform
Other LoRaWAN Network Server.
