An interface circuit for agriculture sensor

An interface circuit for agriculture sensor / Soh Yan Ying
Sensor memainkan peranan yang penting dalam pertanian moden. Pengunaan sensor dalam pelbagai sektor pertanian mengurangkan kejejasan cuaca dan persekitaran terhadap tanaman, meningkatkan hasil dan mengurangkan kos operasi. Industri cendawan merupakan sebuah industri yang baharu dan kecil berbanding dengan industri pertanian yang lain di Malaysia. Daya pengeluaran cendawan di Malaysia tidak mampu memenuhi permintaan pasaran. Pengimportan cendawan semakin meningkat setiap tahun dan jumlahnya telah mencapai 10 juta tan pada 2012. Oleh sebab kebanyakan ladang cendawan di Malaysia adalah secara kecil-kecilan, daya pengeluaran ladangladang tersebut telah dihadkan oleh sistem kawalan yang kurang sesuai dan kekurangan sumber kewangan. Projek ini membentangkan sebuah litar antaramuka sensor pertanian bagi memantau dan mengawal keadaan persekitaran dalam sebuah ladang cendawan. Projek ini dibina menggunakan sebuah sensor suhu dan kelembapan, sebuah sensor karbon dioksida, sebuah perintang peka cahaya, sebuah papan mikrokontroler Arduino Uno, dan sebuah modul Wi-Fi. Sistem ini mampu mendapatkan data daripada sensor yang diletakkan di ladang cendawan dan meghantar data tersebut ke awan ‘ThingSpeak’ untuk penyimpanan. Data tersebut boleh diakses oleh pengguna melalui ‘ThingSpeak’. Arduino Uno digunakan untuk proses data yang didapati, lalu mengawal peralatanperalatan di ladang cendawan seperti pelembap udara, kipas dan lampu untuk mengekalkan persekitaran yang optimum untuk pertumbuhan cendawan. Suhu, kelembapan, kepekatan karbon diosida dan keamatan cahaya yang diukur oleh sistem ini mempunyai peratusan ralat serendah masing-masing 0.4%, 1.5%, 2.2% and 1.34%. _______________________________________________________________________________________________________ Agriculture sensors play an important role in modern agriculture. The use of sensors in various agriculture sectors minimises the environmental impact on crops, helps in increasing yield and saving cost of operation. Among all agriculture industries in Malaysia, the mushroom industry is a comparatively new and small industry. The production of mushrooms in Malaysia is unable to meet the demand in local markets. Import of mushrooms has been increasing every year and the amount has reached 10 million tons of mushrooms in 2012. As most of the mushroom farms in Malaysia are small-scaled, their production capability is limited by inadequate environmental control system and the lack of financial resources to upgrade the systems. This project presents an agriculture sensor interface circuit to monitor and control the environmental conditions in a mushroom farm. It utilizes a temperature and humidity sensor, a carbon dioxide sensor and a light dependent resistor, the Arduino Uno microcontroller board, a Wi-Fi module. The system is able to acquire data from the sensors that are placed in the mushroom farm and send the data to ThingSpeak cloud for storage. The data can be accessed via ThingSpeak and an Android app designed alongside the project. Arduino Uno is used to process data acquired from the sensors and control the appliances such as humidifier, fan and light in the mushroom farm to regulate the environmental condition. The temperature, humidity, carbon dioxide and the light measured using the circuit developed have percentage error as low as 0.4%, 1.5%, 2.2% and 1.34% respectively.
