1. Introduction

S31502 is a multi-sensor device based on Amazon Sidewalk. It can be used to implement door

magnetism switch detection, PIR detection, and glass breaking state detection.

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. S31502 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) PIR

Detect infrared

There are people: report 1

There are no people: report 0

➢Report follows IR disable time and IR detection time rules.

IR detection time rules:

IRDisableTime and IRDectionTime are parameters defining S31502’s behavior after it detects motion.

IRDisableTime is the sampling period while IRDetectionTime is detecting period.

By default, IRDisableTime is 30 seconds and IRDetectionTime is 5 minutes.

When S31502 is triggered, S31502 will be turned off for first 70% of IRDisableTime to save power and

then turned on for rest 30% of IRDisableTime.

If living creature is detected during the rest 30% of IRDisableTime, the IR delay time will be

extended for another IRDetectionTime until no infrared signal is detected.

If no living creature is detected during IRDetectionTime, S31502 will report un-occupied along with

other sensor status.

Example1:

While IRDetectionTime is 60 secs and IRDisableTime is 30 secs, no living creature is detected after

triggered.

S31502 will report un-occupied after 60 secs(IRDetectTime).

Example2:

While IRDetectionTime is 60 secs and IRDisableTime is 30 secs, living creature is detected during 25th sec.

S31502 will restart IR detect procedure(IRDetectionTime).

No living creature is detected during next IRDetectionTime and S31502 therefore report un-occupied.

(3) Glass Break

No broken glass detected: report 0

Broken glass detected: report 1

IRDisableTime = 30s

IRDetectionTime = 60s

5. Set up Instruction

--- On/Off ---

Power on/Turn on Insert batteries.

Press function key until the 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 devi

ce 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

Press and hold the key for 4

seconds

Turn off the infrared detection function.

*Applicable to device with PIR

--- 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 Voltage2.4V

6. Data Report

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)

Note:

The device report interval will be programmed based on the default firmware.

The interval between two reports must be the minimum time.

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.

Example#2 based on MinTime = 15 Minutes, MaxTime= 1 Hour, Reportable Change i.e.

BatteryVoltageChange= 0.1V.

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.
