2. Introduction
WS433-O2 is the Wireless Ambient Oxygen Sensor, it utilises galvanic cell type oxygen sensor which provides a linear
output voltage signal relative to percent oxygen present in a particular atmosphere. The sensor features no position
dependency, excellent chemical durability, and it is not influenced by CO. 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 cato 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, hospital, cleanroom...

5. Operation Principle 5.1 Process of measurement When the sensor sampling time interval is reached, For example 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. - Page 5 (add up to 40 nodes) . After 5 minutes Enb_auto_add_sensors will automatically = 0. Memmap resgisters You can download Modbus Memmap of WS433-CL with the following link: https://filerun.daviteq.com/wl/?id=WBbGm89AToHWyvIyMOc780N1KmjfUr3Y 5.2.2 Add sensor node into WS433-CL-04 (1) through intermediate WS433-CL-04 (2) and Modbus In case the sensor need to be added to WS433-CL-04 (1) has been installed in a high position, the sensor cannot be brought close to WS433-CL-04 (1).
