A monitoring technology for large area with low-cost and high efficiency is highly demanded. Wireless Sensor Network (WSN) is the solution for a monitoring technology. However, not all monitoring must be continuous, there are some monitoring that can be carried out periodically. Therefore it is possible to invent a mobile sensor communication system on multicell networks. This research aims to implement a WSN system by collecting data from mobile sensors on multicell networks. The focus of research is on the design of mobile sensor communication with low-cost device as transceivers, namely NodeMCU. The design is implemented using 4 NodeMCU units, 3 of them are functioned as access points, while 1 unit is employed as a client connected to the sensor. The experimentation was conducted by varying transmission distances of sensors with and without barriers. Moreover, handover and blankspot areas are also included accordingly. The result of experimentation shows that the usage of low-cost devices has still possibility to built monitoring mechanism on multicell networks eventhough the transmission power was significantly influenced by the availability of barriers.
