Wireless Ambient Humidity & Temperature Sensor is a combination of wireless sensor transmitter WS433-M12F and
sensor ATH, it utilises Digital capacitance humidity sensor to deliver high accuracy and stable measurement. The
wireless portion is Sub-GHz technology from Texas Instruments allows long range transmission at ultra-low power
consumption. It will connect 2-way wirelessly to the wireless co-ordinator WS433-CL to send data and receiving the
configuration. It can be configured the operation parameters like data sending interval, health check cycle...remotely
from Globiots platform or via ModbusRTU software (thru the WS433-CL). Its default data rate is 50 kbps, can be
switched to 625 bps to increase the communication range. It can last up to 10 years with a single AA battery. There are
a lot of applications as environment monitoring for office, warehouse, data center, hospital, agriculture...

Process of measurement
When the sensor sampling time interval is reached, for example 2 minutes, the node will wake up and switch ON the
power supply to supply the energy to external sensor to start the measurement. Depends on the type and
characteristic of external sensor, the sensor will take a certain time to finish the measurement.
For example, the measurement time is 200mS, after this time, the node will read the value of sensor using I2C, node
will switch OFF power supply to external sensor to save energy.
Once reading the sensor value, the raw data is X, it can be scaled to any engineering value by the following formula:
Y = aX + b
Where:
X: the raw value, reading from output of sensor before calibrated/validated;
Y: the calculated value, a desired output value of sensor, after calibrated/validated;
a: constant (default value is 1)
5. Operation principle

b: constant (default value is 0)
By default a= 1 and b=0 ==> Y=X
The Y value will be compared with Lo and Hi threshold.

Just exchange the sensor module but node has not been reset ==>
please take out the battery for 20s then install it again to reset node to
recognize the new sensor module

Logic status of parameters
Hi-Byte is Logic status of parameter 1
If parameter 1's value > high threshold 1 => Hi-Byte of Logic status = 1
If parameter 1's value < low threshold 1 => Hi-Byte of Logic status = 0
If parameter 1 is digital => Hi-Byte of Logic status = parameter 1's value
Timer up 1 = (Total time when Hi-Byte of Logic status = 1)
Timer down 1 = (Total time when Hi-Byte of Logic status = 0)
RisingEdge counter 1 = (Counter value when Hi-Byte of Logic status changes from 0 to 1)
FallingEdge counter 1 = (Counter value when Hi-Byte of Logic status changes from 1 to 0)
Lo-Byte is Logic status of parameter 2
If parameter 2's value > high threshold 2 => Lo-Byte of Logic status = 1
If parameter 2's value < low threshold 2 => Lo-Byte of Logic status = 0
If parameter 2 is digital => Lo-Byte of Logic status = parameter 2's value
Timer up 2 = (Total time when Lo-Byte of Logic status = 1)
Timer down 2 = (Total time when Lo-Byte of Logic status = 0)
RisingEdge counter 2 = (Counter value when Lo-Byte of Logic status changes from 0 to 1)
FallingEdge counter 2 = (Counter value when Lo-Byte of Logic status changes from 1 to 0)

for-long-range-wireless-co-ordinator-ws433-cl
Locate the place where the wireless sensor is mounted, from that locate the position to mount the bracket;
Placing the wireless module on bracket and secure it by 02 x M2 screws (supplied in accessory bag)
Note: The bracket can be mounted on the wireless module in both direction, upward or downward
The mounting bracket is made from hard metallic material. The following steps are for mounting this bracket;
6.1 Reset Sensor Node
6.2 Data rate configuration 625 kps
6.3 Wireless sensor configuration with co-
ordinator
7. Installation
7.1 Mounting bracket installation

The bracket will be fixed on the wall or surface by 2 x M4 screws (supplied by customer) or double-sided 3M tape
(included in accessory bag in carton box);
DO NOT install the wireless module inside a complete metallic box or housing. The RF signal can not pass
through metallic wall;
This wireless module would be installed a semi-metallic box, because the RF signal can pass through the non-
metal wall/are;
The best case is to install the wireles module inside or Non-metallic box;
Some non-metallic materials: plastic, glass, wood, leather, concrete, cement…
7.2 Installation location
7.3 IO Wiring & Sensor installation

The sensor module has M12-male connector which is matched with M12-female connector on wireless module;
Carefully plug the sensor module onto wireless module, using HAND to tighten slowly until stop;
Note: please DO NOT over tightening by hand or other tool, it can damages the M12 connector;
Steps for battery installation:
Using Philips screw driver to unscrew M2 screw at the side of housing
Carefully pull out the top plastic housing in the vertical direction
7.4 Power Supply & Battery installation

NOTE: Because of O-ring, it requires to have much pulling force at the beginning, therefore please do it carefully to
avoid the damage of circuit board which is very thin (1.00mm);
Insert the AA battery, please take note the poles of battery
Insert the top plastic housing and locking by M2 screw

No.
