Modern day population growth and global climate change requires high-yield agricultural systems that can function in harsh environments. Greenhouses can maintain temperature and humidity, while serving as a protective, nurturing alternative to vulnerable farm environments. With weather effects eliminated, greenhouses provide productive environments for experimental agriculture techniques such as hydroponics and aquaculture. These methods of agriculture, specifically aquaculture, require constant monitoring. The failure of electronic devices such as an air pump prove fatal to a fish population in a short time frame. In developing countries, agricultural locations may be a significant distance from a farmer’s home, with no internet or …

Radio Frequency Identification (RFID) systems use electromagnetic signals to wirelessly identify and track RFID-tagged objects. A reader transmits a carrier wave request signal to an RFID tag, which then transmits a unique identification signal back to the reader. Applications include supply chain inventory management, automated toll booth fee systems, sports event timing, restricted access control, pet monitoring and retail theft prevention. An RFID tag includes an antenna connected to a Radio Frequency Integrated Circuit (RFIC). RFID tags in the ultra-high frequency (UHF), industrial, scientific and medical (ISM) 902-928MHz band and global Electronic Product Code (EPC) 860‑960MHz band are powered passively …
