Since this project implement the IOT platform in the water quality monitoring system in the fish farm, a portable WiFi device needs to be used to ensure the system is connected to WiFi the whole time. This is because WiFi connection is needed to ensure that the data collected from the sensors is transferred to the cloud server so that it can be accessed by the user.
For that reason, I'm using the Tenda portable WiFi device or known as Tenda pocket WiFi to solve the WiFi connection problem.

Any sim-card with active internet connection be plug into the Tenda pocket WiFi to enable the WiFi function of the device. However it only supports 3G and 2G connection which means it olnly connects to 3G connection even though 4G LTE supported sim-card is inserted.

The sim-card slot of the Tenda pocket WiFi is shown in the picture above. The WiFi Id and password can be found just below the barcode of the device near to the sim-card slot. After inserting the sim-card, the device needs to be set up first to fully enable the WiFi connection. The steps on the setup for the Tenda pocket WiFi can is as shown here. Despite of it compact size, the Tenda pocket WiFi use a powerful internal battery of 2000mAh that can lasts up to 6 hours which is ideal for extended hours of outdoor use.
