Development of a Multichannel Temperature and Humidity Monitoring Device

Environmental temperature and humidity levels have impacts on organisms and therefore care is taken to measure/monitor and maintain them at certain levels in daily life. In this study, a portable multichannel temperature and humidity monitoring device has been developed. The device houses multiple temperature sensors, a humidity sensor, a microcontroller, a display and a +9V battery. Tests with three temperature sensors show that the device is user-friendly and performs consistent measurements. The device is able to operate thirty-six sensors at maximum and can transfer measurement results to any personal computer or Bluetooth device with universal asynchronous receiver input.
