1.2. Deployment
iWiscloud smart sensor can be deployed individually or paired together with other
iWiscloud smart home solution suite. If Wiscloud control center is deployed together,
user can do remote monitoring and alert via the Internet cloud.
1.3. Proposed deployed locations
Home, Office, Luxury Hotel, Industrial buildings, Precise engineering / clean rooms or
high-tech farms. Anywhere that you may require to monitor & alert or obtain precise
information of the environment.
1.4. Exterior design
Our smart sensors (square or circular) shaped exterior shells are made up from
Acrylonitrile-Butadiene-Styrene (ABS) plastic. It is strong, stable, durable, safe and
resistant to heat and corrosion. The hive inspired air vents enhances aerodynamic
flow and increases reading accuracy.
1.5. Color Options
Black, Silver, Pure White
1.6. Display Panel Standby
1. When the smart sensor detects continuous 5 minutes of low light (dark or
darkness), it automatically goes into display panel standby mode. The display
panel will emerge again when it detects visible light.
2. While in standby mode, if the smart sensor detects a quantitative change in
noise or sensatory value, the display panel will also emerge.
1.7. Product Feature Expansion
1. Each smart sensor carries one RS-485 port interface, used commonly for
industrial communication.

P a g e 4 | 9
2. Each smart sensor is designed with two optional power relays [see section
2.13 for details] which can be used to power control other electronic products.
These relays are activated whenever the smart sensor defined upper limit is
exceeded.
3. Each smart sensor (other than the PM2.5 model) also has an option to
provide a 4-20mA varying electric power source to a single target.
4. For the advanced smart sensor model, each smart sensor can also capture
and perform relay of 315/433Mhz control signals.
2. Configuring iWiscloud Smart Sensor
In this section, we would explain on the configuration options, following settings ->
configuration in chronological order.
2.1. Main display screen
1. The top value indicates the reading of the smart sensor detection attribute
(depending on smart sensor model)
2. The next row with a loud speaker icon indicates the detected sound level.
The higher the sound level detected, the more “_”would appear.
3. The last row indicates the luminosity level detected.
4. If the smart sensors are paired with iWiscloud control centre, the sensor
exact readings can be obtained from the cloud as seen in below diagram.

P a g e 5 | 9
5. The smart sensor will be occasionally blink in blue which indicate that it is
operational.
2.2. Version
In this section, the smart sensor installed firmware version is displayed.
2.3. Address Setting (Nebula)
In this section, the smart sensor can be configured to communicate with iWiscloud
control center. Each control center has its unique Nebula address value and the
iWiscloud smart sensor MUST configure MATCHING Nebula address value for linkage.
Please refer to iWiscloud control center operation manual in finding out the
iWiscloud control center’s unique Nebula address.
2.4. Room Setting
In this section, the smart sensor can be configured to be operating in one of the
default location zone (within home). This is to facilitate for the iWiscloud control
center in identifying the different smart sensors deployed in the different location
within the home. By default, all smart sensors are set as room ID zero (0). Refer to
below table for the other pre-defined zones.

2.5. Warning audio
In this section, the smart sensor can be configured to sound a warning audio when
the defined limits are breached. Default value is off, which meant warning audio is
off. Note: Regardless of the warning audio settings, the smart sensor will be blinking

P a g e 6 | 9
in red light when the defined limits are breached, assuming the Warning status is
turned on [see section 2.7].
2.6. 4-20mA output
In this section, the smart sensor can be configured for direct proportion or inverse
proportion for the 4-20mA output. For direct proportional, the constant power
provided is proportional to the smart sensor reading, starting with 4mA at zero
reading and 20mA at reading above the user defined threshold upper limit.
2.7. Warning
In this section, the smart sensor can be configured whether warning is activated
when defined limits are breached. Default value is “on”, which meant the smart
sensor will blink in red light when defined limits are breached. However, when this
setting is turned “off”, regardless if the warning audio selection, the smart sensor
will not indicate alert status. Also, when this setting is turned “off”, all the power
relays option will never be activated.
2.8. Relay 315M/415M
This option is only available for the advanced model. In this section, the smart sensor
can be configured to do mess network relays for 315/415Mhz control signals.
2.9. Exit
This option exits from the configuration menu.
2.10. Reset
When this option is selected, the smart sensor performs a factory reset and restore
all values to default.
2.11. Calibration
When this option is selected, the smart sensor performs an automated calibration of
measured value.

2.13. Setting up the electrical relays
Please note that the electronic relays only support up to ≤500W and it should be
installed only by qualified trained electrician. The electrical relays are only activated
when the user defined upper limit are met. (For the humiture model, the relays are
activated when either the upper or lower limit threshold are breached). Do note that
the warning option must be “ON”for this relay to be functional.
For power wiring connectivity, please connect up the devices with reference to the
diagram below.
3. Points to note

P a g e 8 | 9
For accurate readings, please avoid install smart sensor in enclosed area.
Please ensure the operating environment is between 0℃to 50℃
Please do not deploy the smart sensor within an enclosed metal cover as this
will affect its wireless communication capabilities
If multiple smart sensors are installed, please install them each at least 2cm
apart.
For best results, please install smart sensor 1.2m above floor level.
Avoid exposing the smart sensor in highly corrosive environment (e.g.
hydrosulfide, hydrochloric, alkali, halogenic, etc..)
Avoid wetting the smart sensor hive surface area as it will reduce in device
detection accuracy
Avoid frosting the smart sensor hive surface area as it would damage the hive
structure and permanently damage device capabilities.
