So, I made an Environment Monitor.
What does it do?- Measures Temperature (in F)
- Humidity (in %)
- Barometric Pressure (in mb)
- Time since code first ran
It uses a DHT11 for humidity and temperature, and a BMP280 for barometric pressure.
How to build?Alright, I got you.
- Plug the DHT 11 into Pin 2
- Using the power rails, create an I2C Bus
- Plug both the BMP280 and the LCD into the I2C Bus
- Give everything a proper power and ground supply
It's how to connect multiple I2C devices to one board.
You can set it up by using the power rails on a breadboard.
Plug SDA into negative or positive, and SCL into the other.
Here's a picture:
The blue and green wires are the bus. The wires on the right go to the board, and the other sets of two go to the BMP280 and the LCD.
That's it!Happy building!
