As a basis is used LPC812 microcontroller. Sensors implement communication with microcontroller via the I2C bus. For communication with the sensor device is used RS485 communication.CPU is associated status indication are 6 LEDs.
Remote Temperature, Humidity, & Airflow Sensor 12′ CordHumidity Sensor: Accuracy (normal range): +/- 2% RH at 25°CTemp Sensor +/- 0.5 °C accuracy – Range: -40°C to 85 °CAir Flow: 0 to 100 (relative value) – End user can calibrate
