4180 Mbed Mini Project-IOT Weather Station
.
Description
For ECE 4180 Lab4 we decided to do a mini design project on IOT Weather station. We used the mBed to do the computation and the BLE chip to send the data to the phone and display on the app.
Components
• mbed LPC1768 • Adafruit Bluefruit LE • HTU21D - Temperature and Humidity Sensor • TMP36 Analog Temperature Sensors • Photocell or Phototransistor
Hardware connections are as follow:
Temp36:
HTU21D: Temperature and Humidity sensor
Light Sensor: we use pin 10 Analog In
We use two Adafruit BLE The first first pin layouts is describe in the picture below. The second Adafruit BLE pin layout is same but this time we used TX to be pin13 and RX to be pin 14.
