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′ Cord
Humidity Sensor: Accuracy (normal range): +/- 2% RH at 25°C
Temp Sensor +/- 0.5 °C accuracy – Range: -40°C to 85 °C
Air Flow: 0 to 100 (relative value) – End user can calibrate
