| According to the current large-scale pig farming characteristics, a piggery temperature and humidity monitoring system based on AVR microcontroller ATmega16 was designed. It consisted of multiple temperature and humidity monitoring points and the central control point. The temperature and humidity monitoring points used SHT15 to complete temperature and humidity data acquisition and processing in different locations Piggery, and then sent data to central control point through the RS485 bus. According to temperature and humidity alarm value, ATmega16 controlled fans and thermostat l devices work. The testing results show that: the system monitors the temperature range of -40~123.8℃, temperature accuracy of 0.2℃and measurement accuracy of 1.8%, fully meet the piggery environment. |
