Installation Guide for Main Device

Check the Location for the best RF Signal

Make sure the site is good enough for RF signal transmission.

Tip: To maximize the transmission distance, the ideal condition is Line-of-sight (LOS) between the LoRaWAN sensor and the gateway. In real life, there may be no LOS condition. However, the LoRaWAN sensor still communicates with the gateway, but the distance will be reduced significantly.

Connect the external Pt100 sensor to Device and install the Device on the Wall/Housing/Structure

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;

DO NOT install the wireless sensor or its antenna inside a completed metallic box or housing because the RF signal can not pass through the metallic wall. The housing is made from Non-metallic materials like plastic, glass, wood, leather, concrete, and cement…is acceptable.

3. ADVANCED GUIDE

3.1 Principle of Operation

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, node will switch OFF power supply to external sensor to save energy.

The measured value is the raw value of the sensor. The measured value can be scaled according to the following formula:

Y = aX + b

• • • • • X: the raw value from the sensor
        • Y: the calculated value for parameter 1's value or parameter 2's value
        • a: constant (default value is 1)
        • b: constant (default value is 0)

So, if there is no user setting for a and b ==> Y = X

The Y value will be compared with Lo and Hi threshold. Please refer below the graph of alarm processing.
