Abstract Biochar is a kind of carbon-rich, highly aromatic and highly stable solid product produced by high temperature thermal cracking of biomass feedstock under complete anaerobic or partial anoxic conditions. It is pyrolyzed at 300~500 °C. Biochar can be prepared from rice straw. Based on the actual needs, this paper proposes a biochar carbonization temperature control technology based on the Internet of Things technology for straw carbonization. The SCADA data monitoring and control system consists of a Modbus-based, Web Access web database and a remote data transmission and local control network. With ADAM-4060 and intermediate relay as the control core, thermocouple, ADAM-4018 data acquisition module, MCGS industrial grade programmable human-machine interface and no Web Access webpage database, remote monitoring of carbonization furnace temperature parameters, and according to the alarm status and warning line alert the manager to control the operation of the blower. The purpose of this paper is to find the optimum carbonization temperature for rice and to control the internal temperature of the carbonization furnace near the optimum temperature.
