Alat pemantau kondisi udara lingkungan adalah perangkat yang mampu memantau kondisi udara lingkungan (temperature wet bulb (twb), temperature dry bulb (tdb), kelembaban realtif (RH) dan tekanan atmosfer) secara kontinyu dan real time melalui transmisi nirkabel. Perangkat ini sangat penting karena informasi kondisi udara lingkungan sangat dibutuhkan di berbagai aspek kehidupan manusia, misalnya bidang pertanian, peternakan, industri, laboratorium, manajemen perkotaan dan kesehatan. Sistem ini merupakan integrasi utama dari sensor-sensor elektronik (temperatur dan kelembaban-SHT11, barometrik pressure sensor-BMP180), mikrokontroler-Arduino Uno dan perangkat komunikasi nirkabel Bluetooth (Bluesmirf Gold). Dari hasil pengujian dan percobaan, perangkat ini mampu memonitor kondisi udara lingkungan dengan tingkat keakurasian 0.5⁰C untuk temperatur, 3.5% untuk kelembaban dan 700~900 hPa/±0.12 hPa untuk tekanan, resolusi 0.01⁰C dan 0.03% dan delay pengiriman data 5.8 detik. Kata Kunci: Sensor, Temperatur, Kelembaban Relatif, Tekanan Atmosfer, Mikrokontroler.

Ambient air condition monitoring device is a equipment that has capability to monitor ambient air conditions (wet bulb temperature (twb), dry bulb temperature (tdb), relative humidity (RH) and the atmosphere of pressure) continuously and real time through wireless transmission. This device is very important because the information of ambient air conditions is needed in the various aspects of human life, such as agriculture, livestock, industry, laboratories, urban management and health. This system is a major integration of electronic sensors (temperature and humidity-SHT11, BMP180 barometric pressure sensor), Arduino Uno microcontroller and Bluetooth wireless communication devices (Bluesmirf Gold). Based on results of the tests and experiments, this device was able to monitor the ambient air condition with accuracy rate is 0.5⁰C, 3.5%, 700~900 hPa/±0.12 hPa for temperature, humidity and atmosphere pressure respectively. Resolution is 0.01⁰C, 0.03% for temperature and humidity respectively and transmission delay is 5.8 second. Keywords: Sensor, Temperature, Relative Humidity, Atmosphere Pressure, Microcontroller.
