1. Introduction
S31501 is a comprehensive detection device with temperature and humidity detection, door magnetic
switch detection, and glass breaking state detection. The S31501 device is suitable for flow control, data
collection, and other applications such as home intelligent terminals and industrial applications.
S31501 has great advantages of durability, nice compact design, multi-function integration, low power
consumption, and convenient installation and use.
The S31501 device integrates the Amazon Sidewalk wireless module KG100S to enable its low power
long range connectivity to the Amazon Sidewalk network over 2.4GHz Bluetooth® Low Energy and
Sub-GHz LoRa/FSK radio technologies. Customers can keep their S31501 device to stay connected on the
Amazon Sidewalk network at no additional costs. The integrated module also enables the highest level of
IoT security from Secure Vault™ technology implemented on the module’s microcontroller unit. Together
with multi layers of data encryption by the Amazon Sidewalk communication protocol, this has brought the
S31501 device to the next level of enabling a versatile sensing solution for person/family/asset protection
while highly securing customers data and protecting their privacy.
Amazon Sidewalk：
Amazon Sidewalk is a shared wireless network that uses Amazon Sidewalk Bridges, such as compatible
Amazon Echo and Ring devices, to enable communication among devices communicating on the network.
Amazon Sidewalk enables reliable, low-bandwidth, and long-range connectivity at home and beyond. It
connects IoT devices and applications such as outdoor lights, motion sensors, and location-based devices. It
uses Bluetooth Low Energy for short-distance communication and CSS and FSK radio protocols at 900
MHz frequencies to cover longer distances.

4. S31501 Sensor Function
(1) Reed Switch
Detect the opening and closing state of the reed switch.
Open: report 1
Close: report 0
➢The reed switch needs to be fixed when used, such as the double sided tape.
(2) Temperature and Humidity Sensor
Detection of temperature and humidity in ambient air.
Temperature unit: 0.01°C, signed value.
Humidity unit: 0.5%
(3) Glass Break
No broken glass detected: report 0
Broken glass detected: report 1
5. Set up Instruction
--- On/Off ---
Power on/Turn on Insert batteries.
Press function key until green indicator flashes once.
Turn off
(Reset to factory setting)
Press the function key for more than 8 seconds, and the green indicator
light will flash continuously.
Release the key after the flash starts, and the device will automatically
shut down after the flash ends.
(Indicator light display: the indicator light will flash once every 2s to
prompt the current pressing duration)
Note
On/off interval is suggested to be about 10 seconds to avoid the
interference of capacitor inductance and other energy storage
components.

--- Network Joining---
Never joined the network
Turn on the device to search the network.
The green indicator stays on for 5 seconds: Success
The green indicator remains off: Fail
Had joined the network (
without
factory resetting)
Turn on the device to search the previous network.
The green indicator stays on for 5 seconds: Success
The green indicator remains off: Fail
Fail to join the network The device should be close to the sidewalk gateway while joining the
network.
--- Function Key ---
Press the function key for more
than 8 seconds
Restore to factory setting/Turn off
The green indicator flashes for 20 times: Success
The green indicator remains off: Fail
Press once
The device is in the network: green indicator flashes once and sends a
report.
The device is not in the network: green indicator remains off
--- Sleeping Mode ---
The device is on and in the
network
Sleeping period: Min Interval.
When the reportchange exceeds setting value or the state changes: send a
data report according to Min Interval.
---Low Voltage Warning----
Low Voltage 2.4V

6. Data Report
Example#1 based on MinTime = 1 Hour, MaxTime= 1 Hour, Reportable Change i.e.
BatteryVoltageChange=0.1V
Note: MaxTime=MinTime. Data will only be report according to MaxTime (MinTime) duration regardless
BtteryVoltageChange value.
When the device is turned on, it will immediately send a version package.
Default setting:
Max Interval: 0x0E10 (3600s)
Min Interval: 0x0E10 (3600s) (Automatically checking the current voltage every Min Interval)
Battery Change: 0x01 (0.1V)
Temperature Change: 0x64 (1°C)
Humidity Change: 0x14 (10%)
Note:
The device report interval will be programmed based on the default firmware.
The interval between two reports must be the minimum time.

Note:
1. The device only wakes up and performs data sampling according to MinTime Interval. When it is sleeping,
it does not collect data.
2. The data collected is compared with the last data reported. If the data change value is greater than the
ReportableChange value, the device reports according to MinTime interval. If the data variation is not
greater than the last data reported, the device reports according to MaxTime interval.
3. We do not recommend to set the MinTime Interval value too low. If the MinTime Interval is too low, the
device wakes up frequently and the battery will be drained soon.
4. Whenever the device sends a report, no matter resulting from data variation, button pushed or MaxTime
interval, another cycle of MinTime / MaxTime calculation is started.

7. Important Maintenance Instruction
Your device is a product of superior design and craftsmanship and should be used with care. The following
suggestions will help you use the warranty service effectively.
•Keep the device dry. Rain, moisture, or any liquid might contain minerals and thus corrode electronic
circuits. If the device gets wet, please dry it completely.
•Do not use or store the device in dusty or dirty environment. It might damage its detachable parts and
electronic components.
•Do not store the device under excessive heat condition. High temperature can shorten the life of electronic
devices, destroy batteries, and deform or melt some plastic parts.
•Do not store the device in places that are too cold. Otherwise, when the temperature rises to normal
temperature, moisture will form inside, which will destroy the board.
•Do not throw, knock or shake the device. Rough handling of equipment can destroy internal circuit boards
and delicate structures.
•Do not clean the device with strong chemicals, detergents or strong detergents.
•Do not apply the device with paint. Smudges might block in the device and affect the operation.
•Do not throw the battery into the fire, or the battery will explode. Damaged batteries may also explode.
