Basestations provide sensors a means to communicate with Mero servers. They are the intermediate between Mero BLE sensors and LoRa or WiFi networking equipment.
The sequence of events is important for proper Mero sensor functionality.
During regular operations, a Mero sensor will send data via BLE signal to the closest basestation at set time intervals. In turn, the basestation will transmit the data through a LoRA or WiFi signal to our router. The router then transmits the data to our modem over Ethernet. Finally, our modem transfers the data over the LTE network to our database in the cloud.
However, during the installation process, the process hierarchy is reversed. We will assume that the cloud services are operating normally. Hence, the priority sequence of installation begins with (1) setting up the modem and router to receive (listen for) data from a basestation. Next, (2) we will need to set up the basestation to receive (listen for) sensor data. Finally, (3) the sensor may be turned on and begin sending data.
Before installing basestations, make sure that the required networking equipment has been setup by familiarizing yourself with the following articles:
We generally have a few rule of thumb we like to use when lending our equipment:
- Install a basestation before setting up sensors in close proximity so that the sensors can confirm being in range using an LED indicator.
- Basestations require a constant 120V power supply within BLE (Bluetooth) range of all paper and traffic sensors. This means the basestation must reside within approximately a 5-7m radius of all sensors. If installation takes place in a washroom, the basestation is best hidden under the sink, in a closet, in a crawlspace, or in the ceiling wherever power can be provided/installed.
- The location should be out of sight and/or out of reach of facility users.
- BLE range is significantly impacted by three factors: concrete barriers, metal piping (especially water pipes), and high voltage/current such as 420V transformers.
- Installing basestations in electrical closets more than 5m away from a sensor will result in range issues (sensor will not be able to transmit data).
