Nowadays, the population growth increases significantly. Indonesian Statistic Agency in 2010, Indonesian population reaches 237.641.326 million people, and increase to 261.890.900 million people in 2017. Because of the large population number, it is necessary to increase the number of food. In this case, Greenhouse, as a modern technology is used to support the demand. Greenhouse is a modern way (or tools) in a farming technique. Farmers could use the greenhouse with any horticultural plants without considering the season. Wireless sensor network can used to monitor and control the greenhouse's temperature, air humidity as well as soil moisture. Multi-hop routing technique is designed to allow communication among nodes and communication between node and sink node. The BER (Bit Error Rate) value gained is 0.2 or 20% from 1000 times of data transfer with 200 times of error. In this research, NRF24L01 was used as the transmitter and receiver device in this research. The specification is 2.5 meter for maximum range, using a multi-hop routing for the communication, and the output power is 0 dBm. This is intended to minimize the chance of data transfer failures. © 2018 IEEE.
