Temperature and humidity measurement for oil palm at tissue culture lab using SHT11 / Nurulanis Mohd. Yusoff

Tissue culture is often a generic term that refers to both organ culture and cell culture and the terms are often use interchangeably. Cell cultures are derived from either primary tissue explants or cell suspensions. Mass reproduction of high yielding palms is a major objective of oil palm tissue culturists. The factors such as temperature, humidity, liquid, phase and gas compositions are critical in producing quality clonal materials using tissue culture process. In Tissue Culture Lab at Malaysian Palm Oil Board (MPOB), users (lab workers) should monitor the young oil palm all the time to make sure it in good condition which in the appropriate temperature and humidity. SHT11 is a suitable sensor to detect temperature and humidity at the young oil palm in the vessel because it is very tiny and robust. This sensor will monitor critical parameters that will be linked to the database and analysis software for storing and analyzing the monitored data. This project are controlled remotely using a 40-pin Microchip 16F877A microcontroller at the monitor station that receives commands via RS232 and translates them into hardware control logic. The PIC connected with Zigbee transceivers that are wireless system for the communication protocol to transmit and receive the temperature and humidity data. The data display at the database and also in graph form in real time.
